Incomplete question. However, I provided a brief about Kinetic energy generation.
<u>Explanation:</u>
Interestingly, Kinetic energy in simple terms refers to the energy possessed by a body in motion.
It is often calculated using the formula E = 
A good example of creating even more kinetic energy is a hand crank toy car that moves after you wind it a little, when the car moves it is generating another measure of K.E.
Below are the choices that can be found from other source:
a. frequency
b. the Doppler effect
c. the resonance effect
<span>d. intensity
The answer is B.
