Answer: Option A. -> only along the peripheral regions of the totality trail.
Answer: (a)Diamond Ring is the phenomenon that occurs along the peripheral regions of the totality tail.As the last bits of sunlight pass through the valleys on the moon’s limb, and the faint corona around the sun is just becoming visible, it looks like a ring with glittering diamonds on it.

Answer: Option A. -> S. Chandrashekhar
Answer: (a)
Answer: (a)
Answer: Option D. -> 75° West and 30° East
Answer: (d) Beirut is in the east of G..M.T. and Lima is five hours behind the G.M.T.We know that 1° is equal to four minutesi.e., 2 hours = 30° East and Beirut is 75° West of G.M.T.

Question 74. Consider the following statements regarding asteroids:
- Asteroids are rocky debris of varying sizes orbiting the Sun.
- Most of the asteroids are small but some have diameter as large as 1000 km.
- The orbit of asteroids lies between orbits of Jupiter and Saturn.
Answer: Option D. -> 1 and 2 only
Answer: (d)Asteroids are rocky debris of varying sizes orbiting the Sun. Most of the asteroids are small but some have diameters as large as 1000 km.There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun’s solar nebula that never grew large enough to become planets.The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter. Asteroids vary greatly in size, from almost 1,000 km for the largest down to rocks just tens of metres across.

Answer: Option D. -> Chandrashekhar limit
Answer: (d)
Answer: (d)
Answer: Option A. -> either a (curvature) singularity or a horizon
Answer: (a)Black holes are regions of spacetime from which nothing, not even light, can escape.A typical black hole is the result of the gravitational force becoming so strong that one would have to travel faster than light to escape its pull.Such black holes contain a spacetime singularity at their centre.

Answer: Option A. -> Venus
Answer: (a)Venus is called the Evening star. Because it trails the Sun in the sky and brightens into view immediately after the Sun sets and when the sky is dark enough. When Venus is at its brightest, it appears visible merely minutes after the Sun has set.

Answer: (d)
Answer: (d)
Answer: Option D. -> Mercury
Answer: (d)There are four terrestrial planets in our Solar System: Mercury, Venus, Earth, and Mars.The terrestrial planets in our Solar System are also known as the inner planets because these planets are the four closest to the Sun.
