Answer:because some energy are lost due to friction
Explanation:some energy are lost due to friction
The variable that changes is the period of the motion.
<h3>What is simple harmonic motion?</h3>
The term simple harmonic motion refers to a regular repeating motion. The acceleration of the SHM is always directed towards the center. The spring is an example of a system undergoing simple harmonic motion.
From the description in the question, the variable that changes is the period of the motion.

Answer:Uniform between the plates
Explanation:
Electric Field due to infinite sheet with uniform charge is given by

Where
=charge density
=Space Permittivity
From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .
You can describe the motion of an object by its position, speed, direction, and acceleration
