The correct explanation for the scenario of a swimmer pushing against the wall of a pool is:

For every action, there is an equal and opposite reaction.

This is Newton's third law of motion, which states that when the swimmer pushes against the wall (action), the wall exerts an equal and opposite force back on the swimmer (reaction), propelling them forward.

Ball A and Ball B are rolled so that they will collide. Data is collected and represented in the table below.

Does the data in the table demonstrate the law of conservation of momentum?

To determine if the data demonstrates the law of conservation of momentum, you need to verify if the total momentum before the collision is equal to the total momentum after the collision.

Based on the provided responses, the correct answer is:

Yes, because the total momentums before and after the collision are equal.

This response confirms that the momentum is conserved in the collision, which is what the law of conservation of momentum states. If the table data shows this equality, then it indeed supports the law. If it doesn't show this equality, then the momentum is not conserved.
