Determine how potential and kinetic energy changes at each position of the pendulum as the ball swings from A to E. Position A:
✔ is all potential

Position B:
✔ is losing potential and gaining kinetic

Position C:

Position D:
✔ is losing kinetic and gaining potential

Position E:

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
