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>
the answer to your question would be D.
I would say Solar Power Engineer.
1) The forces of molecules is how strong they are being held together. Now, we know that solid is the last one, because it's particles are held CLOSELY and VERY TIGHTLY together, which is why it has a definite shape.And last of all, a gas's particles are held freely, which is why it has no shape. So the answer would be:- gas, liquid, solid
3) The state of matter that does not have a definite shape, but has a definite volume is a liquid. So the answer is :- liquid
7) False, an endothermic reaction is when it absorbs energy, and as we know that in a chemical reaction as the following, it tends to be an exothermic reaction, meaning that is releases energy. So the answer is:- FALSE
8) Gases have particles that are far apart (freely) and move fast. So the answer is:- They are moving very fast and are far apart.<span> </span>
