Ashley made a paper boat and attached paperclips to the edges. in order to control her boat she used a horseshoe magnet. how is ashley able to control her boat without touching it? a) the boat is moving with currents in the water. b) the boat is attracted to the magnet by the force of gravity. c) the boat is attracted to the magnet by the force of magnetism. d) ashley would not be able to do this without touching the boat.

The true answer is C.

The boat is attracted to the magnet by the force of magnetism.

Let me explain. If Ashley made the paper boat and place it on the water, gravity will try to pull the boat down, however no magnets are used in this situation.

Now if magnets are used in this situation and the paper clip is attach to the boat, rather than gravity pulling it down, the magnet will be pulling paper clip, causing the boat to move, so instead of gravity, it's magnetism.

Note: Magnets=Magnetism

The answer is C

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
