[NDA1995] They are meteors They are the debris which got separated from a comet 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 2. The distance of the nearest star besides the sun from the earth is : 4.2 light years 4.9 x 1111m 4.3 light years 95 x1015 m 3. The strongest evidence that comets are members of our solar system comes from: [CDS 1992] the shape of their orbits the shape and length of their tails their composition their effect on the lives of man 4. The time required by moonlight to reach the earth is : 1 sec 2 sec 1.3 sec 2.3 sec 5. Consider the following astral bodies: 1. Sirius 2. Venus 3. Mars The correct sequence in decreasing order of their brightness is : [CDS 1999] 3, 2, 1 2, 3, 1 2, 1, 3 1, 2, 3 6. Foucault experiment is proof of which one of the following? [NDA 2008] Rotation of Moon Revolution of Moon Revolution of Earth Rotation of Earth 7. Which of the following celestial bodies bear, ‘The Sea of Tranquility’ and ‘The Ocean of Storms’ ? Moon Mars Sun Venus 8. The same side of the moon always faces the Earth because: [Railways 1994] the period of rotation of the Moon is not equal to the period of rotation of the Earth 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 9. 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 3 4 1 4 2 3 1 2 1 4 3 4 3 1 2 10. If there is no Sun, the colour of the sky would be: black yellow orange blue 11. The constellations of stars appear at different positions in the sky at different times during night mainly: because earth rotates about its axis because of optical illusion because earth revolves round the sun because celestial bodies are changing their positions all the time 12. 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 is much smaller than Jupiter Venus is much closer to the earth 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 reflects lesser amount of sunlight than Jupiter 13. The ‘Solar Corona’ mainly consists of: ice gases cosmic rays molten lava 14. The term ‘meteor’ is applied to an interplanetary body: after it enters the earth’s atmosphere and lands on the surface of the earth without exploding in mid-air 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 before it enters the earth’s atmosphere 15. Who of the following discovered the laws of planetary orbits? [Asstt Comm 2008] Nicholas Copernicus Galileo Galilei Isaac Newton Johanries Kepler 16. The Saturn rings were discovered by: Copernicus Newton Galileo none of these 17. Twelve constellations referred to as zodiac are: [IAS 1989] signs of Roman gods a group of stars none of these imaginary region that encompass the path of the planets 18. The exact time taken by the earth for single rotation on its own axis is: [RRB 1991] 24 hrs 35 sec 23 hrs 56 minutes 4.09 sec 23 hrs 50 minutes 7.2 sec 24 hrs 19. 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 elliptical or hyperbolic orbits, usually accompanied by a shining tail hyperbolic orbit without projecting any tail or head 20. The radiant energy of the sun is transmitted in the form of: particles long waves none of these short waves Loading … Share this:WhatsAppTelegramTweet Related
