A direct current
  a) often changes direction as it flows through a conductor.
  b) may change in magnitude but always flows in the same direction in a conductor.
  c) must always remain constant in magnitude but can travel in any direction through a conductor.
  d) can be used in a circuit with a transformer to change the voltage in that circuit.

Question 2

A horizontal force of magnitude 6.5 N is exerted tangentially on a Frisbee of mass 32 grams and radius 14.3 cm. Assuming the Frisbee, a uniform disk, is originally at rest and the force is exerted for 0.08 s, determine the angular velocity of rotation about the central axis when the Frisbee is released.
