<h2>Answer:</h2>

<u>c. Solstice</u> describes days when sun's rays directly hit Tropic of Cancer and Tropic of Capricorn.

<h2>Explanation:</h2>

The solstices occur due to the declination of the Earth's orbital movement around the sun. During this declination, the axial tilt is 23.5°. Furthermore, solstice's occurrence is during time the sun's direction is overhead the moon.

In Northern hemisphere, the declination is towards Tropic of Cancer with the axial tilt of 23.5°N. It occurs on June 20 & 22 while in the south the normal period of occurrence is between December 20 and December 23. In the south, the solar declination hits Tropic of Capricorn at 23.5°S.

r-ruslan [8.4K]

Answer:

Check Explanation.

Explanation:

In order to be able to answer this question effectively and efficiently we have to consider the Newton's law of Universal gravitation which is given by the mathematical representation below;

Gravitational force, F = G (m1 × m2) / r^2.

Where G = Gravitational constant, m1 and m2 and the masses of body one and two respectively and r = distance.

So, we can deduce that the mass(in form of kinetic energy) increase at large distance and this makes the speed to reduce.
