In this image, matching north poles from two magnets are introduced. What do you predict will be the outcome?

• There will be no interaction.The poles of magnets do not have an effect on one another.

• The two magnets will combine and become one magnet

• The two north poles will attract each other

• The two north poles will repel each other

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity
