The conflict between obedience to authority and personal conscience.

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. What astronomers mean when <span> they say that the sun makes energy by hydrogen burning is that, the Sun is fusing hydrogen into helium and releasing energy. Hope this helps.</span>
We can ignore all that business about resting on the rock and
rolling down part of the way and then resting on the moss.
Its potential energy right now doesn't depend on what happened
to it yesterday. We don't care.
All we care about is that we're walking along in the park and we
notice a 1.5kg rock lying in moss 10 meters above the ground.
Gravitational potential energy
= (mass) · (gravity) · (height)
= (1.5 kg) · (9.8 N/kg) · (10 m)
= 147 (kg · N · m / kg)
= 147 joules
During the period of constant acceleration, the car's average speed is (1/2) (16 + 32) = 24 m/s.
At that average speed, it covers 240 meters in 10 seconds.
