101) Which type of star is maintained by the pressure of an electron gas?
(a) Main Sequence Star
(b) White Dwarf
(c) Neutron Star
(d) Black Hole
Answer: (b)
White dwarfs are stars supported by pressure of degenerate electron gas. i.e. in their interiors thermal energy kT is much smaller then Fermi energy Ep. We shall derive the equations of structure of white dwarfs, sometimes called degenerate dwarfs, in the limiting case when their thermal pressure may be neglected, but the degenerate electron gas may be either non-relativistic. somewhat relativistic. or ultra-relativistic.

102) Which of the following first hypothesized that the Earth orbited the sun?
(a) Alexander the Great
(b) Copernicus
(c) Socrates
(d) Tycho Brahe

109) The precession of the Earth refers to the:
(a) change from night to day.
(b) Earth’s motion around the sun.
(c) change in orientation of the Earth’s axis.
(d) effect of the moon on the Earth’s orbit.
Answer: (c)
Precession is the change in orientation of the Earth’s rotational axis. The precession cycle takes about 19,000 – 23,000 years. Precession is caused by two factors: a wobble of the Earth’s axis and a turning around of the elliptical orbit of the Earth itself (Thomas, 2002). Obliquity affected the tilt of the Earth’s axis, precession affects the direction of the Earth’s axis. The change in the axis location changes the dates of perihelion (closest distance from sun) and aphelion (farthest distance from sun), and this increases the seasonal contrast in one hemisphere while decreasing it in the other hemisphere ( Kaufman, 2002). currently, the Earth is closest to the sun in the northern hemisphere winter, which makes the winters there less severe (Thomas, 2002). Another consequence of precession is a shift in the celestial poles. 5000 years ago the North Star was Thuban in the constellation Draco. Currently the North Star is Polaris in the constellation Ursa Minor.

(b) Kepler and Galileo in 1604.
(c) the Chinese in 1054 A.D.
(d) several ancient civilizations in 236 B.C.
Answer: (c)
The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 A.D., is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The Crab Nebula spans about 10 light-years. In the nebula’s very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

131) On the celestial sphere, the annual path of the Sun is called
(a) the eclipse path.
(b) ecliptic.
(c) diurnal.
(d) solstice.
Answer: (b)
The ecliptic is an imaginary line on the sky that marks the annual path of the sun. It is the projection of Earth’s orbit onto the celestial sphere.

132) The angular distance between a planet and the Sun, as viewed from the Earth, is called
(a) angle of inclination.
(b) elongation.
(c) latitude.
(d) opposition.
Answer: (b)
Elongation is the angular distance between the sun, and another object such a moon or a planet as seen from earth. There are several special names for these angular distances. The different names of these angles depend on the status, inferior or superior, of the planet. The planets closer to the sun than the earth are called inferior planets. The planets farther away from the sun than earth are called superior planets.
Elongation is measured from earth as the angle between the sun and the planet. Sometimes the apparent relative position of a planet in relation to the sun is called the aspect, or configuration, of a planet.

133) Which of the following has the highest density?
(a) Earth
(b) Venus
(c) Mars
(d) Jupiter
Answer: (a)
Earth has the highest density of any planet in the Solar System, at 5.514 g/cm3. This is considered the standard by which other planet’s densities are measured. In addition, the combination of Earth’s size, mass and density also results in a surface gravity of 9.8 m/s². This is also used as a the standard (one g) when measuring the surface gravity of other planets.

134) Which of the following planets is NOT a terrestrial planet?
(a) Earth
(b) Jupiter
(c) Mars
(d) Mercury
Answer: (b)
The term terrestrial planet is derived from the Latin “Terra” (i.e. Earth). Terrestrial planets are therefore those that are “Earth-like”, meaning they are similar in structure and composition to planet Earth. All those planets found within the Inner Solar System – Mercury, Venus, Earth and Mars – are examples of terrestrial planets. Each are composed primarily of silicate rock and metal, which is differentiated between a dense, metallic core and a silicate mantle.

135) Why do we see lunar eclipses much more often than solar eclipses?
(a) Lunar eclipses occur more often than solar eclipses.
(b) Lunar eclipses last longer than solar eclipses.
(c) The lunar eclipse is visible to much more of the Earth than a solar eclipse.
(d) The moon is closer to the Earth than the sun.
Answer: (c)
Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, we are more likely to see a lunar eclipse than a solar eclipse.

136) A star like object with a very large red shift is a
(a) Neutron star.
(b) Nova.
(c) Quasar.
(d) Supernova.
Answer: (c)
Quasars: In the 1930’s, Edwin Hubble discovered that all galaxies have a positive redshift. In other words, all galaxies were receding from the Milky Way.

137) The apparent magnitude of an object in the sky describes its
(a) Size
(b) Magnification
(c) Brightness
(d) Distance
Answer: (c)

138) The Van Allen belts are:
(a) caused by the refraction of sunlight like rainbows.
(b) charged particles trapped in the Earth’s magnetic field.
(c) caused by the reflection of polar snow.
(d) caused by precession.
Answer: (b)
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation.

139) A coordinate system based on the ecliptic system is especially useful for the studies of
(a) Planets
(b) Stars
(c) The Milky Way
(d) Galaxies
Answer: (a)

140) The mean distance of the earth from the sun in astronomical units is:
(a) 3.7 (b) 10
(c) 1 (d) 101
Answer: (c)
In astronomy, an astronomical unit is defined as the average distance from the Sun to the Earth, or about 150 million kilometers (93 million miles). You can abbreviate astronomical unit as AU.
Since the distances in astronomy are so vast, astronomers use this measurement to bring the size of numbers down.
For example, Earth is 1 au from the Sun, and Mars is 1.523 AU. That’s much easier than saying that Mars is 227,939,000 km away from the Sun.

141) What process produces a star’s energy?
(a) hydrogen and oxygen combustion
(b) nuclear fusion
(c) neutron beta decay
(d) nuclear fission
Answer: (b)
The enormous luminous energy of the stars comes from nuclear fusion processes in their centers. Depending upon the age and mass of a star, the energy may come from proton-proton fusion, helium fusion, or the carbon cycle.

142) What is the most distant object in the sky that the human eye can see without optical instruments?
(a) The Horsehead Nebula
(b) The Andromeda Galaxy
(c) The Sagittarius Constellation
(d) The Aurora Borealis
Answer: (b)
The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy. Andromeda is accompanied by 14 dwarf galaxies, including M32, M110, and possibly M33 (The Triangulum Galaxy).

143) Which civilization developed and implemented the first solar calendar?
(a) Babylonian
(b) Greek
(c) Egyptian
(d) Aztec
Answer: (c)
A solar calendar is a calendar whose dates indicate the position of the earth on its revolution around the sun and is based on the seasonal year of approximately 365 1/4 days, the time it takes the Earth to revolve once around the Sun. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star — Sirius, or Sothis — in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error.

144) What is the HOTTEST region of the sun?
(a) The core
(b) The photosphere
(c) The chromospheres
(d) The corona
Answer: (d)
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere) The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K. The corona cannot be seen with the naked eye except during a total solar eclipse, or with the use of a coronagraph. The corona does not have an upper limit.
A study published in 2012 in Nature Communications by researchers at Northumbria University found a possible mechanism that causes some stars to have a corona that is almost 200 times hotter than their photosphere (the star’s surface).

145) The same side of the moon always faces the Earth because:
(a) the moon is not rotating about its axis.
(b) the moon’s motion was fixed at its creation by the laws of inertia.
(c) tidal forces keep the moon’s rotation and orbiting motion in sync with each other.
(d) the moon’s magnetic poles keep aligned with the Earth’s magnetic field.
Answer: (b)

146) The resolving power of a telescope depends on the:
(a) focal ratio
(b) diameter of the objective
(c) magnification
(d) focal length
Answer: (b)
The resolving power of a telescope depends on the diameter of the telescope’s light-gathering apparatus, or objective. In a refracting telescope, the objective lens is the first lens the light passes through. In a reflecting telescope, the objective is the telescope’s primary mirror. In a Schmidt-Cassegrain telescope, the objective is also the primary mirror. As the diameter of the telescope’s objective increases, the resolving power increases.

147) On a clear, dark, moonless night, approximately how many stars can be seen with the naked eye?
(a) 300 (b) 1,000
(c) 3,000 (d) 10,000
Answer: (c)
On any clear dark moonless night a person can see about 3000 stars of our galaxy without the aid of a telescope

148) The study of the origin and evolution of the universe is known as:
(a) Tomography
(b) cystoscopy
(c) cryology
(d) cosmology
Answer: (d)
Cosmology is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is “the scientific study of the large scale properties of the universe as a whole.”

149) According to Kepler’s Laws, all orbits of the planets are:
(a) ellipses
(b) parabolas
(c) hyperbolas
(d) square
Answer: (a)
Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky.
1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus.
2. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.
3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
Kepler’s laws were derived for orbits around the sun, but they apply to satellite orbits as well.

Rules of Precis Writing

English, Guidelines / admin

Following are the rules of precis writing.

1) Read the given passage carefully at least three times in order to be able to grasp what the writer has said.

2) Underline the important points to be included in your precis. A point is important if it is intimately connected with the main subject and if it is essential for a clear exposition of the theme.

3) Use your own language in the precis. While words and phrases from the original may be used in the precis. Whole sentences should never be lifted out of the original to be included in it.

4) The precis should be roughly one-third of the original passage. Always prepare a rough draft first and count the words. If you find that it is too long, shorten it by removing what seems essential and by condensing phraseology. If it turns out to be too short, read the original to see what more can be added to the precis.

5) Examples, illustrations, and comparisons should be left out of the precis. Figures of speech should be removed and the ideas expressed in clear, direct language.

6) Your own comments on the ideas of the precis are absolutely forbidden. Do not express any opinion, favorable or unfavorable, about the ideas in the original passage.

7) Be very careful about the language you write. Mistakes of Grammar and spelling are penalized as much in the precis as in other forms of composition.

8) See that your precis is a readable piece of English and that its ideas can be understood even by a person who has not gone through the original. This is very important.

9) Your precis should be connected whole. As such it should not be divided into paragraphs. ( THIS RULE DOES NOT APPLY TO VERY LONG ORIGINAL PIECES OF WRITING SUCH AS THOSE SET IN COMPETITIVE EXAMINATIONS).

10) Don’t use the direct form of speech in precis. If the author has written in the first person pronoun using “I” and “my”, you should write in thethird person pronoun: “he” and “his”.

Placement of Women in our society___are Women oppressed or dominant?

Articles, World / admin

What is Feminism?

Feminism is a literary movement of struggle, which endorses the set of ideologies and conviction systems. Feminists assert the equality between both sexes and the emancipation of oppressed women as an equal to men. The word ‘feminism’ can be a daunting and confusing word to some. Many people believe that feminism means hating men or wanting women to rule over everything– this could not be supplementary from the accuracy comas! Feminism simply means believing that men and women are equal, neither is better than the other and neither should be treated with more respect than the other – everyone should be equal on all levels, simple as that.

Why is Feminism important?

Feminism allows equal opportunities for both sexes. Gender roles (a set of conforming rules that say how a person should behave based on their gender) can be destructive to both men and women. The trendy belief is that women and girls are supposed to take care of the home while boys and men are meant to go out and supply for the family. Can you imagine not being allowed to go to school just because you’re a girl? Or being forced to stay at home and look after the house just because you’re a woman? This is the reality that many girls around the world face, even in this modern and urbanized era. Girls are not sent to school just because they are females and are not allowed to sustain the same rights and conveniences that boys hold. This implies the ideology of Patriarchy, means that women are innately inferior to men.

Even today when a woman gets pregnant, people anticipate and hope that it’s a baby boy. No one feels cheerfulness and joy on the birth of a baby girl. These are not biological but rather societal constructs. Feminists don’t deny the biological differences between men and women; but they don’t agree that how such differences as physical size, shape and body chemistry make men naturally superior to women.

What factors make women inferior and submissive to men.

There are abundant factors which chip into the inferiority and sedition of women in our society, but the foremost grounds are their women themselves have constructed their personalities as acquiescent and dependant on men. They have come to accept that they are good for nothing and therefore men have to look after them, be it their fathers, brothers or husbands. Submissive women their whole lives at first make themselves dependant on their fathers and then later in life on their husbands. They don’t even know the meaning of free sense of self, or how will it like to be free woman. Their personalities from the very start are skilfully constructed and they have been taught to internalize the societal norms. They have to deliver what society expects from them.

Effect of media:

Our media sadly is also showing the societal expectations from women, and under many circumstances they are oppressed to keep their mouths shut, no matter of how much pain she must be going through. Failures are expected from women, they’ll say: She couldn’t do it because she is a woman.

“Because I am a woman, I must make unusual effort to succeed. If I fail no one will say, “She doesn’t have what it take” in fact they’ll say, “A woman doesn’t have what it takes”.

Clare Bothe Luce.

On the other hand, Men are not permitted to fail at anything, because failure in any domain implies failure in one’s manhood.

To make this observable fact more lifelike, take the example of Disney’s renowned story Cinderella. It has been scrutinized that childhood stories like these make the young girls to live in the world of imagination and dystopia, because it equates femininity with submission, encouraging women to stomach abuse. Like Cinderella waits uncomplainingly for a man to come and rescue her, and view marriage as the only reward for “right” deportment. The character of Prince Charming which requires men to be wealthy rescuers of the poor beautiful girls is responsible to make their women happy.

“Women’s chains are forged my men, not by anatomy”

Jane Fonda.

The singular rationale of women now is to get married; they don’t try to build their career because at the end they thought it is of no use since they’ll get married someday. After marriage the purpose of women shifted to their husbands. They try so hard to please their husbands and other people sometimes out of inevitability, that they forget their own self-esteem and reverence, whereas men never make women their sole spotlight, he has millions of other things to worry about. He always spends most of his time working and earning money, because it is his responsibility alone. Women’s soaring education (if she gets any) becomes useless after marriage if she doesn’t put it out practically.

It is only women who are told to make sacrifices and compromises, and in doing so they often settle for less than they warrant. Women have to be of specific age, colour and background to get a perfect match, while no such margins apply to men.

“Man endures pain as an undeserved punishment, while women accepts it as a natural heritage”

Anonymous

Solution to the problems:

Well, I am not saying that all women in our society are oppressed and not enjoying equal right as men does, but rather some are. Some husbands are that much supportive that they not only let their wives to do jobs, but they also fight for their feminist rights, and very evidence itself proves that Feminism is not gender biased. It is an ideology. It is a belief system which works for some people and not others. If a man is doing a job, then a woman also could. If a man is an educated doctor than a woman can also achieve that. If a man rides a motorcycle than a woman can also do so. Nothing in this world is gender biased, it is us, this society and our slender minded thinking that has made the matters that much complicated.

A woman should work, not because out of the need for money, but rather to keep herself busy and to focus her mind other than domestic issues. But nothing should be imposed on anyone if she wants to, than she should do whatever she wants because no society and nation as a whole can progress without their women participating in every field of life.

Gender should not be the hindrance in success.

(e) None of these
Answer: (c)
In the past, the title for “most frigid body” went to Pluto, as it was the farthest then-designated planet from the Sun. However, due to the IAU’s decision in 2006 to reclassify Pluto as a “dwarf planet”, the title has since passed to Neptune. As the eight planet from our Sun, it is now the outermost planet in the Solar System, and hence the coldest.

The moons of Mars are Phobos and Deimos. Both moons were discovered in 1877 by Asaph Hall Asaph Hall was about to give up his frustrating search for a Martian moon one August night in 1877, but his wife Angelina urged him on. He discovered Deimos the next night, and Phobos six nights after that. Ninety-four years later, NASA’s Mariner 9 spacecraft got a much better look at the two moons from its orbit around Mars. The dominant feature on Phobos, it found, was a crater 10 km (6 miles) wide — nearly half the width of the moon itself. It was given Angelina’s maiden name: Stickney.

69) This is the greatest amount of water vapor the air could hold at a certain temperature
(a) Absolute humidity
(b) Relative humidity
(c) Variable humidity
(d) None of these
Answer: (a)
Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3).
The maximum absolute humidity of warm air at 30°C/86°F is approximately 30g of water vapor – 30g/m3. The maximum absolute humidity of cold air at 0°C/32°F is approximately 5g of water vapor – 5g/m3.

(a) Orion
(b) Columbia
(c) Canis Major
(d) Taurus
(e) None of these
Answer: (a)
(Canis Major is a constellation in the southern sky. Its name means “the greater dog” in Latin.) Orion, which is located on the celestial equator, is one of the most prominent and recognizable constellations in the sky and can be seen throughout the world.

74) Which of the following explains the reason why there is no total eclipse of the sun? (CSS-2009)
(a) Size of the earth in relation to that of moon
(b) Orbit of moon around earth
(c) Direction of rotation of earth around sun
(d) Area of the sun covered by the moon
(e) None of these
Answer: (b)

75) Where do most of Asteroids lie? (CSS-2009)
(a) In asteroid belt between the orbits of Mars and Jupiter
(b) In asteroid belt between the orbits of Mars and Venus
(c) In asteroid belt between the orbits of Jupiter and Venus
(d) Everywhere in the sky
(e) None of these
Answer: (a)
Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter. Scientists estimate the asteroid belt also contains more than 750,000 asteroids larger than three-fifths of a mile (1 km) in diameter and millions of smaller ones. Not everything in the main belt is an asteroid — for instance, comets have recently been discovered there, and Ceres, once thought of only as an asteroid, is now also considered a dwarf planet.

76) The largest circular storm in our solar system is on the surface of which of the following planets?
(a) Jupiter
(b) Venus
(c) Uranus
(d) Earth
Answer: (a)
Jupiter boasts the largest storm in the Solar System . It is called the Great Red Spot and has been observed for hundreds of years that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth. Today, scientists know the Great Red Spot is there and it’s been there for a while, but they still struggle to learn what causes its swirl of reddish hues.

77) The biggest asteroid known is:
(a) Vesta
(b) Icarus
(c) Ceres
(d) Eros
Answer: (c)
Ceres, a dwarf planet and the largest asteroid in the solar system yet known. Discovered in 1801 and first thought to be a planet and then an asteroid, we now call Ceres a dwarf planet. Gravitational forces from Jupiter billions of years ago prevented it from becoming a full-fledged planet. But Ceres has more in common with Earth and Mars than its rocky neighbors in the main asteroid belt. There may even be water ice buried under Ceres’ crust.

78) Rounded to the nearest day, the Mercurian year is equal to:
(a) 111 days
(b) 87.97 days
(c) 50 days
(d) 25 days

(a) Jupiter’s moon Callisto
(b) Venus
(c) Saturn’s moon Titan
(d) Mars
Answer: (d)
Olympus Mons is the largest volcano in the solar system. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption. Olympus Mons rises three times higher than Earth’s highest mountain, Mount Everest, whose peak is 5.5 miles above sea level.

80) One Jupiter day is equal to which of the following?
(a) 30 hrs 40 min
(b) 9 hrs 50 min
(c) 3 hrs 20 min
(d) 52 hrs 10 min

(a) a conjunction
(b) an opposition
(c) a sidereal period
(d) a synodic period.
Answer: (d)
Synodic period , in astronomy, length of time during which a body in the solar system makes one orbit of the sun relative to the earth, i.e. The synodic period of the moon, which is called the lunar month, or lunation, is 291/2 days long; it is longer than the sidereal month.

84) The Hertzsprung-Russel Diagram of stars DIRECTLY compares what TWO of the following properties of stars?
(a) size
(b) temperature
(c) luminosity
(d) Both b & c
Answer: (d)
One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their color (hence effective temperature). Independently in 1913 the American astronomer Henry Norris Russell used spectral class against absolute magnitude. Their resultant plots showed that the relationship between temperature and luminosity of a star was not random but instead appeared to fall into distinct groups.

The majority of stars, including our Sun, are found along a region called the Main Sequence. Main Sequence stars vary widely in effective temperature but the hotter they are, the more luminous they are, hence the main sequence tends to follow a band going from the bottom right of the diagram to the top left. These stars are fusing hydrogen to helium in their cores. Stars spend the bulk of their existence as main sequence stars. Other major groups of stars found on the H-R diagram are the giants and supergiants; luminous stars that have evolved off the main sequence, and the white dwarfs. Whilst each of these types is discussed in detail in later pages we can use their positions on the H-R diagram to infer some of their properties.

85) The Andromeda Galaxy is which of the following types of galaxies?
(a) elliptical
(b) spiral
(c) barred-spiral
(d) irregular
Answer: (b)
The Andromeda Galaxy also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kilo parsecs (2.5 million light-years) from Earth

86) About how many light years across is the Milky Way? Is it:
(a) 1,000
(b) 10,000
(c) 100,000
(d) 1,000,000
Answer: (c)
100 000 light years across
A light-year is precisely equal to a whole number of meters, namely 9460730472580800 m or approximately 9.46073 1015 m. That’s the distance traveled by light in a vacuum, at a speed of 299792458 m/s, during a “scientific year” of 31557600 s. All these numbers are exact… In particular, “Einstein’s Constant” is exactly c = 299792458 m/s, because of the latest definition of the meter, officially adopted in 1983.

87) Who was the first man to classify stars according to their brightness. Was it:
(a) Aristarchus
(b) Pythagoras
(c) Copernicus
(d) Hipparchus
Answer: (d)
The first person to classify stars by their apparent magnitude (brightness) was Hipparchus in about 130 BC. He divided the stars into classes based on how bright they appeared in the night sky. The brightest stars were classified as magnitude 1, those that were just visible to the naked eye as magnitude 6. In practice the intensity of a magnitude 1 star is 100 times that of a magnitude 6 star, so the 5 magnitude steps correspond to a multiple of 100. For a geometric series of magnitudes each magnitude must be a times the intensity of the previous one with a5 – 100. This means that going up one magnitude increases the intensity by a factor of a = 2.51. So magnitude 3 is 2.51 times as intense as magnitude 4 and so on.

88) For what reason was the Schmidt telescope specially built? Was it to serve as:
(a) a sky camera
(b) a radio telescope
(c) an optical telescope
(d) a solar telescope
Answer: (a)

A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.

89) The greatest distance of a planet from the sun is called what? Is it the planet’s:
(a) aphelion
(b) perihelion
(c) helix
(d) eccentricity
Answer: (a)
The closest point to the Sun in a planet’s orbit is called perihelion. The furthest point is called aphelion

90) How is the atmospheric pressure of Mars as compared to the atmospheric pressure of the earth? Is it:
(a) about the same as the earth’s
(b) about 100 times as great as the earth’s
(c) about 1/200th that of the earth’s
(d) half as much as that of the earth’s
Answer: (c)
The atmosphere and (probably) the interior of Mars differ substantially from that of the Earth. The atmosphere is much less dense and of different composition, and it is unlikely that the core is molten.
The atmosphere has a pressure at the surface that is only 1/200 that of Earth. The primary component of the atmosphere is carbon dioxide (95%), with the remainder mostly nitrogen. Seasonal heating drives strong winds that can reach 100 mph or more, stirring up large dust storms. Clouds form in the atmosphere, but liquid water cannot exist at the ambient pressure and temperature of the Martian surface: water goes directly between solid and vapor phases without becoming liquid.

91) A typical galaxy, such as our Milky Way galaxy, contains how many billion stars? Is it approximately:
(a) 10 billion
(b) 40 billion
(c) 400 billion
(d) 800 billion
Answer: (c)
According to astronomers, our Milky Way is an average-sized barred spiral galaxy measuring up to 120,000 light-years across. Our Sun is located about 27,000 light-years from the galactic core in the Orion arm. Astronomers estimate that the Milky Way contains up to 400 billion stars of various sizes and brightness.
According to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.

92) A comet’s tail points in which direction?
(a) toward the sun
(b) toward the earth
(c) behind the comet in its orbit
(d) away from the sun
Answer: (d)
Comet tails are expansions of the coma. Comet tails point away from the Sun, regardless of the direction in which the comet is traveling. Comets have two tails because escaping gas and dust are influenced by the Sun in slightly different ways, and the tails point in slightly different directions.

93) Spectral line splitting due to the influence of magnetic fields is called:
(a) Boltzmann Effect
(b) Zeeman Effect
(c) Planck Effect
(d) Zanstra’s Effect
Answer: (b)
The Zeeman effect is the splitting of a spectral line by a magnetic field. That is, if an atomic spectral line of 400 nm was considered under normal conditions, in a strong magnetic field, because of the Zeeman effect, the spectral line would be split to yield a more energetic line and a less energetic line, in addition to the original line at 400 nm.

94) Which of the following is true for ORION? Orion is:
(a) the brightest star in the sky
(b) a constellation
(c) the name given to a NASA spacecraft

Answer: (a)

99) The Magellanic Clouds are
(a) irregular galaxies
(b) spiral galaxies
(c) elliptical galaxies
(d) large clouds of gas and dust
Answer: (a)

10 Important Climate Change Facts

Articles / admin

1) Temperatures are breaking records around the world:

The 21st century has seen the most temperature records broken in recorded history. 2016 was the hottest year on record since 1880, according to NASA, with average temperatures measuring 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean Since the 1950s, every continent has warmed substantially. NASA’s latest visualizations, above, make that reality stark.

2) There is no scientific debate about the reality of climate change:

Multiple studies show that a massive 97 per cent of researchers believe global warming is happening But climate change is considered only the third most serious issue facing the world by the world’s population, behind international terrorism and poverty, hunger and the lack of drinking water

3) Arctic sea ice and glaciers are melting:

Arctic sea ice coverage has shrunk every decade since 1979 by 3.5 to 4.1 per cent. Glaciers have also been in retreat, including in major mountain ranges like the Alps, Himalayas and Rockies. In 2017, Arctic sea ice reached a record low for the third straight running

4) Sea levels are rising at their fastest rate in 2,000 years:

Levels are currently rising at their fastest rate for more than 2,000 years and the current rate of change is 3.4mm a year. In July, a massive crack in the Larson C ice shelf finally gave way sending a 5,800 square km section of ice into the ocean. The newly formed iceberg is nearly four times the size of London.

5) Climate change will lead to a refugee crisis:

An average of 21.5 million people have been forcibly displaced since 2008 due to climate changed-related weather hazards, according to the United Nations High Commissioner for Refugees.

6) Two-thirds of the Great Barrier Reef has been damaged as a result of climate change:

In April 2017, it was revealed that two-thirds of Australia’s Great Barrier Reef has been severely damaged by coral bleaching. As a result, the coral loses its vibrant appearance, turns white and becomes weaker. Scientists say it will be hard for the damaged coral to recover.

7) The ocean is 26 percent more acidic than before the Industrial Revolution:

The pH of ocean surface water has decreased by 0.1, which makes them 26 percent more acidic now than at the beginning of the Industrial Revolution. The waters are more acidic now that at any other point in the last 300,000 years.

8) Global flooding could triple by 2030:

The number of people exposed to flooding each year is at risk of tripling from 21 million to 54 million by 2030, This would result in the economic costs of flooding increasing from £65 billion to around £340 billion.

9) More greenhouse gases are in our atmosphere than any time in human history:

The concentration of carbon dioxide in the atmosphere reached the milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016

10) Earth could warm by six degrees this century:

The Earth’s temperature will continue to rise so long as we continue to produce greenhouse gases. The estimates for how much temperature will increase by 2100 range from two degrees Celsius to as much as six degrees Celsius.

The universe, Galaxy, Light Year, Solar System, Sun, Earth, Astronomical System of Units

1) The biggest planet in our solar system is (CSS 2013)

(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (c)
In terms of mass, volume, and surface area, Jupiter is the biggest planet in our Solar System by a wide margin.
Size and Mass:
Jupiter’s mass, volume, surface area and mean circumference are 1.8981 x 1027 kg, 1.43128 x 1015 km3, 6.1419 x 1010 km2, and 4.39264 x 105 km respectively. To put that in perspective, Jupiter diameter is roughly 11 times that of Earth, and 2.5 the mass of all the other planets in the Solar System combined.

2) The universe is ———-. (CSS 1996)

(a) Stationary
(b) Expanding
(c) Contracting
(d) None of these
Answer: (b)
In June 2016, NASA and ESA scientists reported that the universe was found to be expanding 5% to 9% faster than thought earlier, based on studies using the Hubble Space Telescope

3) The atmosphere of moon consists of: (CSS 2013)

(a) . 90% Hydrogen, 10% Nitrogen
(b) . 80%Nitrogen, 20% Hydrogen
(c) 60% Nitrogen, 40%inert gases
(d) None of these
Answer: (d)
The Moon has no atmosphere. None. That’s why astronauts have to wear their spacesuits when they get outside of their spacecraft on the surface of the Moon.
Atmosphere of the Moon might be electro statically levitated moon dust. These tiny particles are constantly leaping up and down off the surface of the Moon.

4) Who gave the first evidence of the Big- Bang theory?

(a) Edwin Hubble
(b) Albert Einstein
(c) S. Chandrasekhar
(d) Stephen Hawking
Answer: (a)
The Hubble Space Telescope was named after astronomer Edwin Powell Hubble (1889–1953), who made some of the most important discoveries in modern astronomy. Dr. Hubble determined that the farther a galaxy is from Earth, the faster it appears to move away. This notion of an “expanding” universe formed the basis of the Big Bang theory, which states that the universe began with an intense burst of energy at a single moment in time — and has been expanding ever since.

5) Which one of the following planets has largest number of natural satellites or moons?

(a) Jupiter
(b) Mars
(c) Saturn
(d) Venus
Answer: (a)
In the Solar System, there are 179 satellites. A majority of those moons belong to the planet of Jupiter, the second most belonging to Saturn.

6) Which of the following planets rotates clock wise?

(a) Mars
(b) Jupiter
(c) Venus
(d) Mercury
Answer: (c)
Venus is the only planet that rotates clockwise. Venus (radius 3,760.4 miles) is similar to Earth (radius 3,963.19 miles) in size and structure but spins very slowly; a day on Venus is 243 Earth days long.

7) Which of the following order is given to the planets of solar system on the basis of their sizes?

(a) Jupiter, Saturn, Uranus, Neptune
(b) Saturn, Jupiter, Mercury, Earth
(c) Mercury, Earth, Jupiter, Saturn

Saturn (58,232 km / 36,184 miles) – 945% the size of Earth
Uranus (25,362 km / 15,759 miles) –400% the size of Earth
Neptune (24,622 km / 15,299 miles) – 388% the size of Earth
Earth (6,371 km / 3,959 miles)

8) The time taken by the Sun to revolve around the center of our galaxy is

(a) 50 Million years
(b) 100 Million years
(c) 250 Million years
(d) 365 Million years
Answer: (c)
the Sun is dragging us around the galaxy at around 800,000km/h, taking around 250 million years to complete a single orbit.
That means our Solar System has made around 18 complete circuits since it was formed around 4.5 billion years ago.

9): The planet having the largest diameter is

(a) Earth
(b) Jupiter
(c) Venus
(d) Uranus
Answer: (b)
Jupiter is composed primarily of gaseous and liquid matter. It is the largest of the four giant planets in the Solar System and hence its largest planet. It has a diameter of 142,984 km (88,846 mi) at its equator

10) The planet Mercury completes one rotation around the sun is (CSS 2010)

(a) 88 days
(b) 365 days
(c) 98 days
(d) 60 days
(e) None of these
Answer: (a)
A year on Mercury is just 88 days long. One solar day (the time from noon to noon on the planet’s surface) on Mercury lasts the equivalent of 176 Earth days while the sidereal day (the time for 1 rotation in relation to a fixed point) lasts 59 Earth days. Mercury is nearly tidally locked to the Sun and over time this has slowed the rotation of the planet to almost match its orbit around the Sun. Mercury also has the highest orbital eccentricity of all the planets with its distance from the Sun ranging from 46 to 70 million km.

11) The biggest planet in our solar system is (CSS 2013)

(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (c)
Jupiter is the largest planet in the solar system. Jupiter has a mean radius of 43,440.7 miles (69,911 kilometers), about a tenth that of the sun. However, its rapid rotation — it spins once every 9.8 hours

12) The atmosphere of moon consists of: (CSS 2013)

(a) 90% Hydrogen, 10% Nitrogen
(b) 80%Nitrogen, 20% Hydrogen
(c) 60% Nitrogen, 40%inert gases
(d) None of these
Answer: (d)
The Apollo 17 mission deployed an instrument called the Lunar Atmospheric Composition Experiment (LACE) on the moon’s surface. It detected small amounts of a number of atoms and molecules including helium, argon, and possibly neon, ammonia, methane and carbon dioxide.

13) Which of the following explains the reason why there is no total eclipse of the sun? (CSS 2009)

(a) Size of the earth in relation to that of moon
(b) Orbit of moon around earth
(c) Direction of rotation of earth around sun
(d) Area of the sun covered by the moon
(e) None of these
Answer: (d)
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface.

14) The sun produces most of its energy by (CSS 2012)

(a) Nuclear fusion which involves converting “H” to “He”
(b) Nuclear fission involving the burning of uranium & plutonium
(c) Nuclear fission involving the combining of uranium and palladium
(d) None of these
Answer: (a)
Sun, like all stars, is able to create energy because it is essentially a massive fusion reaction.
The core of the Sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into molecules of helium (He) This is possible thanks to the extreme pressure and temperature that exists within the core, which are estimated to be the equivalent of 250 billion atmospheres (25.33 trillion KPa) and 15.7 million kelvin, respectively.

15) Although the mass of a man on moon remains same as on the earth he will (CSS 2012)

(a) Be much happier there
(b) Weigh one sixth as much
(c) Weigh twice as much
(d) None of these
Answer: (b)
The Moon’s gravity is one sixth of the Earth’s gravity. A 120 kg astronaut weighs 1200 N on Earth. On the Moon they would weigh only 200 N. The astronaut’s mass is 120kg wherever they are.

(a) North to south
(b) South to north
(c) East to west
(d) West to east
Answer: (d)
The Earth rotates from the west towards east. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth’s axis of rotation meets its surface.

18): Name two planets which revolve around their axis from east to west

(a) Earth and Venus
(b) Mars and Earth
(c) Venus and Uranus
(d) Mars and Uranus
Answer: (c)
Planets have no light of their own and all of them expect Venus and Uranus, rotate upon their axis from west to east.

19) Our sun is classified as (CSS 2012)

(a) A Blue giant
(b) A Yellow dwarf
(c) Supernova
(d) None of these
Answer: (b)
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth’s atmosphere. Stars generally get bigger as they grow older

20): Name the planet which revolve approximately 90 degree with its orbital plane_.

(a) Neptune
(b) Venus
(c) Uranus
(d) Jupiter
Answer: (c)

(c) Ursa Minor
(d) Scorpio
Answer: (b)

23): All the stars appear to move from

(a) North to south
(b) South to north
(c) East to west
(d) West to east
Answer: (c)
Every day, the Sun, Moon, planets, and stars appear to rise in the east and set in the west. Actually, these celestial objects aren’t moving that fast, but Earth is. It spins on its axis from west to east approximately every 24 hours.
Because we are standing on Earth’s surface, we move along with it. To us, it appears as if everything in the sky is moving from east to west.

24): The body burning like a star and coming towards the earth

(a) Comet
(b) Meteor
(c) Ceres
(d) Satellites
Answer: (b)
Fleeting trails of light are called meteors or shooting stars and they are created by small particles, some no bigger than a grain of rice, as they are completely burned up high in the atmosphere: about 100 km (or 60 miles) above the Earth. They are over literally in the blink of an eye. Space debris is collectively termed meteoroids, those larger fragments that reach the ground are called meteorites. Very big meteoroids are also known as asteroids. If one collides with Earth it would cause a major catastrophe.

37) Orbital period of the planet Mercury around the sun is: (CSS 2009)

(a) 88 days
(b) 365 days
(c) 2 years
(d) 98 days
(e) None of these
Answer: (a)
Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. But here’s the thing. Because of Mercury’s slow rotation (once every 58.646 days) and its rapid orbital speed (47.362 km/s), one day on Mercury actually works out to 175.96 Earth days.
