0-4 energy levels and 0-8 valence electrons please help

How is the gravitational force related to the distance between two objects?

How do you tell if someone actually cares about you? and just say they do?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
