Answer:
8.33 minutes
Explanation:
First let us find out how much time it takes for the light for the sun to reach the earth
Distance between Earth and Sun is 1.5×10¹¹ m
Speed of light = 3×10⁸ m/s

Converting to minutes

So, it takes 8.33 minutes for the light from the sun to reach Earth.
This means that we would be receiving light for 8.33 minutes after the Sun turned off.
Answer:
Without this slack, a locomotive might simply sit still and spin its wheels. The loose coupling enables a longer time for the entire train to gain momentum, requiring less force of the locomotive wheels against the track.

C.
Because it’s falling it has acceleration in the y direction. If you have acceleration, you usually also have velocity, and since kinetic energy is KE= Mv^2 you know you have it. It also has potential energy because it has some height to it, and PE= Mgh.
