What happens when a dog pulls on a leash according to Newton's Third Law of Motion?

• The leash pulls back on the dog with equal strength in the opposite direction.

• The leash absorbs the force and does nothing.

• The leash pulls back on the dog with less strength in the same direction.

• The leash moves away from the dog.
