Select the correct response that provides evidence to support the following claim.

Claim: Gravitational interactions are attractive and depend on the masses of interacting objects and the distances between them.

Options:

The Moon is too small to exert any gravitational force on the Earth.

,

The Sun exerts an equal amount of gravitational force on all objects in the solar system because it is the center of our solar system.

,

Jupiter is the center of our solar system because it is the most massive object in our solar system.

,

It takes Neptune longer to orbit the Sun than it takes for Mercury to orbit the Sun because the gravitational force exerted on Neptune is less than the gravitational force exerted on Mercury due to Neptune's distance from the Sun..

Back

It takes Neptune longer to orbit the Sun than it takes for Mercury to orbit the Sun because the gravitational force exerted on Neptune is less than the gravitational force exerted on Mercury due to Neptune's distance from the Sun..
