[NDA1995] They are the debris which got separated from a comet They are meteors They emit light due to extremely high temperature caused by friction while they are passing through earth’s atmosphere They are a kind of a star 3. The time required by moonlight to reach the earth is : 2 sec 1.3 sec 2.3 sec 1 sec 4. Consider the following astral bodies: 1. Sirius 2. Venus 3. Mars The correct sequence in decreasing order of their brightness is : [CDS 1999] 2, 1, 3 2, 3, 1 1, 2, 3 3, 2, 1 5. The Saturn rings were discovered by: none of these Copernicus Galileo Newton 6. 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 7. The strongest evidence that comets are members of our solar system comes from: [CDS 1992] the shape and length of their tails their composition the shape of their orbits their effect on the lives of man 8. If there is no Sun, the colour of the sky would be: black orange blue yellow 9. Comets are celestial bodies moving about the solar system in hyperbolic orbit always accompanied by a shining head elliptical orbits usually accompanied by a long shining tail hyperbolic orbit without projecting any tail or head elliptical or hyperbolic orbits, usually accompanied by a shining tail 10. 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 11. Which of the following celestial bodies bear, ‘The Sea of Tranquility’ and ‘The Ocean of Storms’ ? Venus Moon Sun Mars 12. The radiant energy of the sun is transmitted in the form of: short waves long waves none of these particles 13. 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 2 1 4 3 2 3 4 1 4 2 3 1 4 3 1 2 14. The same side of the moon always faces the Earth because: [Railways 1994] Moon cannot change its position Moon and the Earth have gravitational force the period of rotation of the Moon is not equal to the period of rotation of the Earth the period of rotation of the Moon on its axis and period of revolution around’ the Earth is almost the same 15. 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 16. The distance of the nearest star besides the sun from the earth is : 4.2 light years 4.3 light years 4.9 x 1111m 95 x1015 m 17. The constellations of stars appear at different positions in the sky at different times during night mainly: because celestial bodies are changing their positions all the time because earth revolves round the sun because earth rotates about its axis because of optical illusion 18. Foucault experiment is proof of which one of the following? [NDA 2008] Rotation of Moon Revolution of Earth Revolution of Moon Rotation of Earth 19. The term ‘meteor’ is applied to an interplanetary body: before it enters the earth’s atmosphere after it enters the earth’s atmosphere and explodes in mid air as a ball of fire after it enters the atmosphere of the earth after it enters the earth’s atmosphere and lands on the surface of the earth without exploding in mid-air 20. The ‘Solar Corona’ mainly consists of: molten lava cosmic rays ice gases Loading … Share this:WhatsAppTelegramTweet Related
