Yurem is pulling a wagon across the playground with a force of 10 N. He asks Elian a to help. She agrees and pushes the back of the wagon in the same direction with a force of 12 N. What is the net force acting on the wagon?

22N

Explanation:

Net force = F1 + F2

=12+10=22N

Both forces are applied in the same direction. So the net force 22N causes a change in the body's state of rest. When several forces act in a body, the body will move in the direction of the net force.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
