31. The time required by earth in 360 degree rotation to make a star return to the same position is called …………day?
[A] Solar Day
[B] Sidereal Day
[C] Real Day
[D] Synodic day
Show Answer
Correct Answer: B [Sidereal Day]
Notes:
The spinning of the earth on its polar axis is in fact takes 23 hours, 56 minutes and 4.09 seconds for rotation through the 360 degree. This is called sidereal day. During the time needed by the Earth to complete a rotation around its axis (a sidereal day), the Earth moves a short distance (approximately 1°) along its orbit around the sun. So, after a sidereal day, the Earth still needs to rotate a small additional angular distance before the sun reaches its highest point. A solar day is, therefore, nearly 4 minutes longer than a sidereal day.
32. On Summer Solstice, Sun’s rays fall perpendicular on which among the following circles?
[A] Tropic of Capricorn
[B] Equator
[C] Tropic of Cancer
[D] None of them
Show Answer

Notes:The solstice refers to the events when the Sun’s apparent position in sky reaches its northernmost or southernmost extremes. Solstice happens twice a year, and twice a year happen the equinoxes. Altogether, the four are considered to start 4 seasons.
- At the time of northern solstice, sun is perceived to be directly overhead the 23.44° north known as Tropic of Cancer.
- Likewise, at the southern solstice the same thing happens for latitude 23.44° south, known as the Tropic of Capricorn.

Notes:
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It is named after the Roman goddess of love and beauty. It is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to Sun, and bulk composition. It has no natural natural satellite. But it is radically different from Earth in other respects. It has densest atmosphere of four terrestrial planets, consisting of more than 96% CO2. The atmospheric pressure at its planet’s surface is 92 times that of Earth

[B] Venus
[C] Earth
[D] Mars
Show Answer
Correct Answer: B [Venus]
Notes:
Venus rotates on its polar axis backwards compared to Earth, so a Venus sunrise occurs in the west and sunset in the east.
39. Where on the earth is located the Sirohi Point?

[B] Indian Ocean
[C] Caribbean Sea
[D] Antarctica
Show Answer
Correct Answer: D [Antarctica]
