By Hubble theory in which universe is expanding,
Answer:
A
Explanation:
An object in motion will stay in motion unless acted upon by an external force.
Say you rolled a ball on the ground, eventually it will stop because of friction and gravity
Either 25% or 75%. does it to how much is wasted or the difference in the input and waste?
B. Gamma rays
Gamma rays have highest energy
Unclear/incomplete question. However, I inferred you need an explanation of the phenomenon of rainfall.
<u>Explanation</u>:
Basically, the phenomenon of rainfall follows a natural cycle called the water cycle. What we call <em>'rainfall'</em> occurs when water condensed (in liquid form) in the atmosphere is made to fall down on the ground as tiny droplets as a result of the forces of gravity.
<u>The water cycle makes rainfall possible:</u>
- First, water on the earth's surface is evaporated (or is absorbed into) the atmosphere.
- Next, it then condensed into liquid form; which later falls to the surface to the ground again. And the process continues.
