Me on 7& 8. it would be really appreciated. : ) i will be giving brainiest.

The answer to your question is below

Explanation:

For question seven, from the posible solutions, the only one that has units of acceleration is the first one, 2.00 m/s², My answer is 6.00 m/s², but in the solutions 6.00 m/s has units of velocity not acceleration, so I would choose the first option.

The law of Newton that says that for every action there is and equal but opposite reaction is the third law,

the answer is a. hope this .

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
