The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
Temperature is a measure of the average kinetic energy of the particles of a substance.
Hope this helps! :)
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,

So, her kinetic energy right before she hits the water is equal to 2450 J.
Answer:
0.066m
Explanation:
use the formula
velocity= frequency × wave length
344m/s = 5200Hz× wavelength
wavelength = 344m/s/5200Hz
wavelength = 0.066m(to 2 sig fig)
The answer is C
