Answer: The kinetic energy in physics can be defined as the energy possessed by the body when it is in motion relatively to the other bodies. This energy depends on the mass of the body and the square of the velocity. Its measurable unit is in Joules.
Answer and Explanation:
Given data:
The electric field is
E

Explanation:
The time in which the animal B overtake animal A according to the motion map is at 2 seconds.
<h3>What is a Motion map?</h3>
This is referred to as one-dimensional plots built off of a position line and depicts velocity and acceleration.
The time in which Animal B is ahead of animal A is at 2 seconds which therefore makes it the most appropriate choice.

<span>D. The speed of light, traveling in a vacuum, will not change if the light source is moving.
The speed of light in a vacuum is always constant regardless of the speed the source or you are travelling at.</span>
