Cameron and Morgan are each holding a bar magnet with opposite poles facing each other. They walk in opposite directions until they stop feeling their magnet pull towards the other one. What can they conclude about the distance between them when they stop feeling their magnets pull?
They are outside the magnetic field of their magnets.
The distance made the magnets' force stronger.
The magnetic fields are far enough apart to change direction.
The magnetic field was weaker when they were close.

A student claims that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the student's claim?
If the distance between two objects increases, the gravitational force between the objects will decrease.
If the distance between two objects decreases, the gravitational force between the objects will disappear.
If the distance between two objects increases, the gravitational force between the objects will increase.
If the distance between two objects decreases, the gravitational force between the objects will not change.
