A horizontal disk rotates about a vertical axis through its center. Point P is midway between the center and the rim of the disk, and point Q is on the rim. If the disk turns with constant angular velocity, which of the following statements about it are true?

A) P & 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
