When we apply pressure on the one side of balloon the other side bulges out due to the movement of gas to other side.
<h3>What happen when we press one side of the balloon?</h3>
If we press one side of the balloon, the other side bulges out because the gas that present on one side moves to the other side where there is no pressure. The body of balloon is elastic so when we apply pressure the other side bulges out.
So we can conclude that when we apply pressure on the one side of balloon the other side bulges out due to the movement of gas to other side.

The purpose of an experiment is to LEARN the EFFECT of something.
The way you do that is to CHANGE the thing and see what happens.
You can change as many things as you want to. But If you change
TWO things and observe the result, then you don't know which one
of them caused the effect you see.
Or maybe BOTH of them working together caused it. You don't know.
So your experiment is not really much good. You need to do it again.
The answer is D, or Outer Space.
Explanation:
Sound is implemented through mechanical wave transferral, which requires a medium (solid, liquid, or gas) to travel through. Because sound is a mechanical wave, it cannot travel through vacuums (space).
Because the box keeps going straight at the same speed, while the seat under it speeds up, slows down, or changes direction.
