[NDA1995] They are meteors They are a kind of a star They emit light due to extremely high temperature caused by friction while they are passing through earth’s atmosphere They are the debris which got separated from a comet 2. Which of the following celestial bodies bear, ‘The Sea of Tranquility’ and ‘The Ocean of Storms’ ? Moon Venus Sun Mars 3. Comets are celestial bodies moving about the solar system in elliptical orbits usually accompanied by a long shining tail hyperbolic orbit without projecting any tail or head hyperbolic orbit always accompanied by a shining head elliptical or hyperbolic orbits, usually accompanied by a shining tail 4. The constellations of stars appear at different positions in the sky at different times during night mainly: because earth rotates about its axis because celestial bodies are changing their positions all the time because earth revolves round the sun because of optical illusion 5. The time required by moonlight to reach the earth is : 2.3 sec 2 sec 1 sec 1.3 sec 6. The ‘Solar Corona’ mainly consists of: gases ice molten lava cosmic rays 7. The same side of the moon always faces the Earth because: [Railways 1994] Moon and the Earth have gravitational force Moon cannot change its position the period of rotation of the Moon on its axis and period of revolution around’ the Earth is almost the same the period of rotation of the Moon is not equal to the period of rotation of the Earth 8. Match the following: Planet Gases in atmosphere A. Venus 1. Hydrogen and helium B. Mars 2. Hydrogen, helium, ammonia, methan C. Saturn 3. Carbon dioxide, amonia and methane D. Jupiter 4. Carbon dioxide and nitrogen A B C D 4 3 1 2 2 3 4 1 4 2 3 1 2 1 4 3 9. The Saturn rings were discovered by: Galileo Newton none of these Copernicus 10. The distance of the nearest star besides the sun from the earth is : 4.3 light years 4.9 x 1111m 95 x1015 m 4.2 light years 11. The radiant energy of the sun is transmitted in the form of: none of these short waves particles long waves 12.

If there is no Sun, the colour of the sky would be: orange blue black yellow 14. Foucault experiment is proof of which one of the following? [NDA 2008] Rotation of Earth Revolution of Moon Revolution of Earth Rotation of Moon 15. The strongest evidence that comets are members of our solar system comes from: [CDS 1992] the shape of their orbits their composition the shape and length of their tails their effect on the lives of man 16. While Venus is seen only for one to two hours either after sunset or before sunrise, Jupiter is seen for the whole night whenever it is visible in the sky. The reason for this is that: [CDS 2000] Venus reflects lesser amount of sunlight than Jupiter the orbit of Venus is inside the earth’s orbit whereas the orbit of Jupiter lies outside the orbit of the earth Venus is much smaller than Jupiter Venus is much closer to the earth than Jupiter 17. Consider the following astral bodies: 1. Sirius 2. Venus 3. Mars The correct sequence in decreasing order of their brightness is : [CDS 1999] 2, 3, 1 1, 2, 3 2, 1, 3 3, 2, 1 18. Twelve constellations referred to as zodiac are: [IAS 1989] a group of stars signs of Roman gods imaginary region that encompass the path of the planets none of these 19. Who of the following discovered the laws of planetary orbits? [Asstt Comm 2008] Johanries Kepler Isaac Newton Galileo Galilei Nicholas Copernicus 20. The exact time taken by the earth for single rotation on its own axis is: [RRB 1991] 24 hrs 23 hrs 50 minutes 7.2 sec 23 hrs 56 minutes 4.09 sec 24 hrs 35 sec Loading … Share this:WhatsAppTelegramTweet Related
