According to the passage, how does longer collision time change the impact force on an object?

It spreads the force over a longer time.

It changes the velocity of the object.

It adds more padding to the object.

It makes the force on the object greater.

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.
