Answer:
See description
Explanation:
Frist we need to know the longitude of tape which is unwinding. Such relationship can be obtained with arc length. An arc length is the distance bewteen two points in a curve.
The relationship is:
Where 
is the arc length or distance, theta is the angle that results from the initial point of the measure to the final point, and r is the radius of a circumference.
Now let 
be length the unwinded tape. Change by and you ge the relationship:
if you unwind the tape by one revolution (
) you get the perimeter of a cricle 
, if you unwind it two times then 
and so on.
Then we have that the derivative of is 
so we replace:
the derivative of theta with respect to t is ω(t) by definition:
The result is the relationship between angular velocity and the velocity and tangential velocity at the point r
The closer objects are the more gravitational interaction between the two. The farther away the objects the less gravitational interaction between the two.

Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.
Chemical potential energy is position of electrons in specific substance bonds that can be broken (energizes).
