Answer:
A)friction
Explanation:
The friction of air resistance slows down the acceleration due to gravity for real-world objects.
Air resistance is a form of friction found in atmosphere.
Frictional force is a force that opposes the motion of a body. It acts in the opposite direction of motion. Friction slows down real-world objects moving through the air.
Without friction, motion will not be possible.
A, C, and D are true when a light spot appears, so those are false.
The answer is therefore B.
<span>The number of oscillations that a wave completes per unit of time is called "frequency".
Frequency represents in fact how many complete cycles of the wave are done in a single unit of time. It can be written also as
