Answer:
a)
b)
c)
Explanation:
From the question we are told that
Mass of soft rubber
Spring compression
Stiffness constant
Ball Distance
Frictional force
a)Generally the equation for motion of the second ball according to Newton's law is given by
b)Generally for speed to be at maximum spring force must equal frictional force
At distance
Therefore
Ball is at maximum speed at
c)Generally maximum velocity is represented mathematically as
Answer; the free encyclopedia. In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.

Solution:
Assuming the potential is zero at infinite distance from the charge, then the potential at a certain distance r from a single point charge is
where
is the Coulomb's constant.
In our problem, we just have to superimpose the potential generated by every charge. The diagonal of the square is
, therefore the distance between each charge and the center of the square is
.
So, the total potential is:
Answer:
Multiple choice answer would be "None"
Explanation:
White dwarfs are radiating stored heat from earlier reactions.
Technically, it would be the last fusion stage the star went through
BEFORE it became a white dwarf, but that's nit-picking.
A is the answer to the question
