  If the disk turns with constant angular velocity, which of the following statements about it are true? (There may be more than one correct choice.)
  A) P and Q have the same linear acceleration.
  B) Q is moving twice as fast as P.
  C) The linear acceleration of Q is twice as great as the linear acceleration of P.
  D) The linear acceleration of P is twice as great as the linear acceleration of Q.
  E) The angular velocity of Q is twice as great as the angular velocity of P.
