D

The altitude of the stars from various points on the earth's surface varies

Explanation

At the time of the solar eclipse it is not the shadow of the earth that is visible on the surface of the sun. The solar eclipse occurs when the moon comes between the sun and the earth. The shadow of the earth is visible during the lunar eclipse.

Q 21. The colour of the star is an indication of its

A

Distance from the earth

B

Distance from the sun

Temperature

D

Luminosity

Explanation

The color of the star Ls an indication of its temperature. The glowing is caused by something called Black-Body radiation, which has to do with the heat energy trying to radiate away in more and more energetic wavelengths. Red stars are relatively cool at only a few thousand degrees Celsius, white stars arc hot at about ten thousand degrees, and blue stars are the hottest.

Triton

Explanation

Ganymede is the largest satellite in solar system. Ganymede is a satellite of Jupiter and the largest moon in the Solar System. It is the seventh moon and third Galilean satellite outward from Jupiter. Completing an orbit in roughly seven days, Ganymede participates in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. It has a diameter of 5,268 km (3,273 mi), 8% larger than that of the planet Mercury, but has only 45% of the latter's mass.

Q 24. The principle of Black hole was enunciated by

A

C.V. Raman

B

H.J. Bhabha

S. Chandrashekhar

D

H. Khurana

Explanation

The principle of Black hole was enunciated by S. Chandrashekhar. A Black Hole is a region of space-time from which gravity prevents anything, including light, from escaping. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole, there is a mathematically defined surface called an event horizon that marks the point of no return. The hole is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.

Q 25. The distance of Moon from the Earth is

384 thousand kms.

B

300 thousand kms.

C

350 thousand kms.

D

446 thousand kms.

Explanation

The distance of moon from the Earth is 384 thousands kms. The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary, having 27% the diameter and 60% the density of Earth, resulting in 1/81 its mass.
