Answer:
200 N
Explanation:
Given that,
A ball traveling at 15 m/s hits a bat with a force of 200 N.
We need to find the force that the bat moving at 20 m/s hit the ball with.
We know that, this probelm is based on Newton's third law of motion. The force that the ball exerting on bat should be equal to the force that the bat exerting in the ball but in opposite direction.
It would mean that the ball hits the ball with a force of 200 N. Hence, the correct option is (a).

The presence of potential energy between particles supports the shape of a heating curve.
<h2>Potential energy and heating curve</h2>
The existence of potential energy between particles supports the shape of a heating curve because potential energy causes the heating curve flat as well as in curve form. The heating curves show how the temperature changes as a substance is heated up.
The potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing so when the heating curve go flat it means there is potential energy so we can conclude that the existence of potential energy between particles supports the shape of a heating curve.

The natural light display called aurora borealis is located in the northern
hemisphere.
There are two types of aurora which are called aurora borealis and aurora
australis. The aurora borealis is located in the Northern hemisphere while
the aurora australis is located in the Southern hemisphere.
They receive their energy through the interaction of charged particles
on the Sun and Earth to produce the light display. An example
of the interaction involves solar wind with atoms of the upper atmosphere.
