Answer:
The protons must feel a repulsive force from the other neighboring protons. This is where the strong nuclear force comes in. ... If they can't get that close, the strong force is too weak to make them stick together, and other competing forces (usually the electromagnetic force) can influence the particles to move apart.^o^
The spring constant, k will be 18 N/m.The ratio of force to one unit of displaced length is known as the spring constant.
<h3>What is the spring constant?</h3>
Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant,K=?
The formula for the spring constant when the spring is oscillate at the given amplitude A:

Hence, the spring constant, k will be 18 N/m
