A pendulum is released from rest from at position A. Derive an equation to determine the centripetal force acting in the pendulum at point C in terms of H, g, and any present forces.

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
