Nuclear power plant are used to generate electricity. In these power plant energy is produced by fission in the nuclear reactor.
The most common fuel used for the production of energy is U-235.

Their are things call solar tides which are the effects of the sun But it would be alot calmer with out the moon.
Answer:
a = -4/5 m/s^2
Explanation:
Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
a = (20 m/s - 60 m/s) / 50 s
a = -40 m/s / 50 s
a = -4/5 m/s^2
