Two balls of different masses are dropped from a building, and they hit the ground at the same time. How does the force of gravity, exerted on each ball, depend on its mass?
A
It is independent of the ball’s mass.
B
It is directly proportional to the ball’s mass.
C
It is inversely proportional to the ball’s mass.
D
It is directly proportional to the ball’s mass squared.

speed and velocity, c would be my guess

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them
