Answer:
This is the equation for elastic potential energy, where U is potential energy, x is the displacement of the end of the spring, and k is the spring constant.
U = (1/2)kx^2
U = (1/2)(5.3)(3.62-2.60)^2
U = 2.75706 J

Explanation:
Since the block is not moving, it only has potential energy and no kinetic energy.
energy = mgh = 8 x 9.81 x 20 = 1569.6J
Answer:
A
Explanation:
I'm just guessing I'll be honest I don't know
That is an example of a Law. Specifically, that is called as
Law of Magnetism. It is one of the physical laws or scientific laws we have. A
physical law is a theoretical statement is the conclusions of repeated scientific
observations and experiments over the year.
