Two forces act together on an object on a horizontal frictionless surface as shown. If the magnitude of the block’s acceleration is -5.0 m/s2, what is the net force acting on the object?

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?

Amaterial that provides resistance to the flow of electric current is called a(an) (1 points)

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
