The two variables that affect the gravitational force between two objects are (1 point)

A. Mass and speed
B. Density and speed
C. Mass and distance
D. Velocity and distance

C. Mass and distance

The two variables that affect the gravitational force between two objects are mass and distance.

To understand this, you can refer to Newton's law of universal gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

So, the correct answer is option C: Mass and distance.

C. Mass and distance
