Answer:

Atmospheric refraction causes the Sun to be seen while it is still below the horizon. Light from the lower edge of the Sun's disk is refracted more than light from the upper edge. This reduces the apparent height of the Sun when it appears just above the horizon.

<h3>What is The Law of Gravity?</h3>

According to Newton's law of gravity, every particle of matter in the universe is attracted to every other particle with a force that varies directly as the product of their masses and inversely as their distance from one another.

Properties of Gravity -

  • It is a universal attractive force. It is directly proportional to the product of the masses of the two bodies.
  • It obey inverse square law.
  • It is the weakest force known in nature.

Examples of Gravity -

  • The force that holds the gases in the sun.
  • The force that causes a ball you throw in the air to come down again.
  • The force that causes a car to coast downhill even when you aren't stepping on the gas.

v₀=0 m/s

H₀=0 m

g=10 m/s²

t=7,2 s

H - ?

H= H_{0} + v_{0}t+\frac{gt^{2} }{2}   \\

H = 0 +0 × 7.2 + 10(7.2)²/2

H = 36m

What is inside of a blackhole ?
horsena [70]
We don't know. A black hole is a star that has collapsed into its own gravity. The gravity in fact, is so strong that even light cannot get through it. That's why it looks black to us.
