Stephen and andy are sitting next to each other on a bench. according to the law of universal gravitational there should be a gravitational force between them. why don't they feel this force?

A.) Universal Gravitational only applies to objects that are far from earth's surface

B.) The gravitational force is balanced out by the force of friction.

C.) The gravitational force between them is extremely small.

D.) The gravitational attraction is balanced by an equal and opposite gravitational repulsion

C.) The gravitational force is balanced out by the force of friction.

C. The gravitational force between them is extremely small.

Explanation:

The force of gravity is based off of the mass and distance of two objects. Stephen and Andy don't have large enough masses to feel an effect.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
