If a tennis player's arm muscles are weak and unable to produce enough force with one hand to accelerate the ball sufficiently, he can create more total force by hitting with two hands. Which of the following principles best describes why this occurs?

a. Newton's law of action-reaction
b. An object will gain more momentum if more force is applied to it across a period of time.
c. Newton's law of inertia
d. Newton's law of acceleration

Newton's law of inertia

Explanation:

This states that, a body will continue to be at rest or moving at a constant speed in a straight line, unless it is acted upon by a force.

The force could be internal or external.

Since the player's one hand can't produce the desired effect on the tennis ball and his two hands can produce more force to put the tennis ball in motion, then the law of inertia is being obeyed here.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
