The increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.
Kinetic energy of a particle is directly proportional to its temperature.
A ball initially at rest acquires kinetic energy when an external force is applied to it. As the person strikes the ball with a bat, the ball gains momentum which increases its kinetic energy of the ball.
Temperature on the other hand, is the measure of the average kinetic energy of a particle. Consequently, as the kinetic energy of the ball increases, the temperature of the ball increases as well.
Thus, we can conclude that the increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.

Answer:
The Republican party was formed because they wanted??????
Explanation:
Visible light is safe for animals because it provides them with warmth.
Answer:
v2f = +15.8 m/s
Explanation:
Conservation law of linear momentum:
m1v1i + m2vi2 = m1v1f + m2v2f
Given:
m1 = 1.1 × 10^3 kg
m2 = 2.3 × 10^3 kg
v1i = +22.0 m/s
v2i = 0
v1f = -11.0 m/s
v2f = ?
Re-arranging the conservation law, we get
m1v1i = m1v1f + m2v2f
Solving for v2f,
m2v2f =m1(v1i - v1f)
or
v2f = m1(v1i - v1f)/m2
= (1.1 × 10^3 kg)(22.0 m/s - (-11.0 m/s))/(2.3 m/s)
= (1.1 × 10^3 kg)(33.0 m/s)/(2.3 × 10^3 kg)
= +15.8 m/s
Answer:
B-No change
Explanation:
Using Ohm's Law, V=IR, you can solve for the current and get V/R=I
Plugging in 1/2V and 1/2 R into the equation you will get 
=I. As a result, the 1/2s cancel out, leaving no change on the current.
