PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.
P.E = m * g * h OR P.E. = mgh
m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.
K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.
K.E = 1/2 mv² where m = mass of the body; v = velocity with which the body is moving.
The wavelength<span> can always be determined by </span>measuring<span> the distance between any two corresponding points on adjacent </span>waves<span>. In the case of a longitudinal </span>wave, awavelength measurement<span> is made by </span>measuring<span> the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

Well both ends of the magnet have a diffrent magnetic force. i hope this was the answer you where looking for, and have a nice rest of the day
Answer:
About 2.19 seconds
Explanation:
Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:
Hope this helps!
