5A. A teacher is demonstrating Newton's Third Law of Motion using a string, straw, and balloon. She blows up the balloon with air and attaches the balloon to the straw. Then, she lets go. The two objects that we will focus on are the air and the balloon. If this is the case, then what is the action and reaction force? The action force is .

The reaction force is
5B. How can you relate the balloon moving forward to Newton's Second Law of Motion?
6A. A student throws a ball against a wall. What are the action and reaction forces in this example?

you would expect a sound wave to speed up. - b)

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
