Hot air rises<span> because when you </span>heat air<span> (or any other gas for that matter), it expands. When the </span>air<span> expands, it becomes less dense than the </span>air<span>around it. The less dense </span>hot air<span> then floats in the more dense cold </span>air<span> much like wood floats on water because wood is less dense than water.</span>
Light energy is defined as how nature moves energy at an extremely rapid rate, and it makes up about 99% of the body's atoms and cells, and signal all body parts to carry out their respective tasks. An example of light energy is the movement of a radio signal.
Answer: Elastic
Explanation:
A collision means the event in which two or more bodies exert forces on each other in about a relatively short time. And only Elastic works with this definition.
Acceleration is the rate of change of velocity, and velocity is the change in displacement over the change in time so the answer would be A.
