An action-reaction pair would be a pair in which one of the elements exerts a force on the other element (action), and then the other element would respond to this force by exerting another force in the opposite direction (reaction).
From the given choices, we will see that:
For choice A, the moon exerts a force on the earth by pulling it (action) and the earth responds to this force by pulling the moon (reaction in opposite direction of the action).
Therefore, the correct choice would be:
A. <span>The Moon Pulls on Earth, and Earth pulls back on the moon.</span>
Answer:
A
Explanation:
You did not list the options. However, knowing the possible options from having seen the material myself - I can infer that the answer option is A. I apologize sincerely if this is wrong.
Answer:
human potential energy
Explanation:
It is given that, before a ball rolls down a hill, it has gravitational potential energy.
Before a rubber ball bounces away from a surface, it has elastic potential energy.
Human potential energy allows us to throw a ball. While throwing a ball, we have to apply some force by our muscles in order to done some work.Also, we know that the capacity to do work is called energy.
Hence, the correct option is (D) " human potential energy ".
This high specific heat of water prevents abrupt changes in temperature and helps the body maintain temperatures that are relatively constant.
