Imagine being somewhere in the universe free from all gravitational and frictional influences. While you are there, you throw a baseball. That ball will:

A.
Move forward, and gradually stop moving.

B.
The ball will not move at all.

C.
The ball will continue to move forward with the same speed and direction.

D.
None of the above.

It depends on what it’s asking. Answer B seems most likely because without friction you are unable to even through the ball, the force on it would throw you backwards and it wouldn’t move. However, if you are able to throw the ball it would be answer C because there’s nothing acting on the ball to stop the motion. It depends on the context of the problem and which you think applies better

We can infer that star y is closer but other factors must be considered including the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contain less heat.
