A student is experimenting with two sets of balls colliding in a closed system. In the first trial, two hard balls collide for 0.01 seconds.

In the second trial, two softer balls collide for 0.02 seconds.

The amount of force applied to each set of balls is equal.

Which statement is correct about these trials?

The momentum in the first trial is half the impulse in the second trial.

The impulse in the first trial is half the impulse in the second trial.

The momentum in the first trial is twice the impulse in the second trial.

The impulse in the first trial is twice the impulse in the second trial.

A

The momentum in the first trial is half the impulse in the second trial

Explanation:

Given that a student is experimenting with two sets of balls colliding in a closed system. In the first trial, two hard balls collide for 0.01 seconds.

In the second trial, two softer balls collide for 0.02 seconds.

The amount of force applied to each set of balls is equal.

Impulse = product of force and time.

While

Momentum = product of mass and velocity.

Impulse = momentum.

Since the force applied to the two balls are the same.

The impulse for the first experiment = 0.01F

The impulse for the second experiment = 0.02F

We can therefore conclude that: The momentum in the first trial is half the impulse in the second trial

ok

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
