A) No, because the moon moves at an unchanging speed.
B) No, because the moon is not accelerated.
C) Yes, because there must be a force to keep the moon moving.

Shown following are six different types of light that travel to Earth from sources in space. Rank these types of light from left to right based on the altitude in the atmosphere where they are completely absorbed, from highest to lowest (Earth’s surface). If two (or more) of the choices reach the same altitude or the surface, rank them as equal by dragging one on top of the other(s).
