Answer:

A substance that removes carbon dioxide gas

If the distance between two objects is cut in half what happens to the gravitational force?
Rina8888 [55]

Answer:

decreases

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
