Question

1. 
   A simple pendulum suspended in a rocket ship has a period T0. Assume that the rocket ship is near the earth in a uniform gravitational field. Give ALL correct answers, i.e., B, AC, BCD... .
   
   A) If the mass of the pendulum doubles, the period increases.
   B) If the ship moves upward with a constant velocity, the period decreases.
   C) If the ship accelerates upward, the period increases.
   D) If the length of the pendulum is doubled, the new period will be: the square root of two times T0.
   E) If the ship accelerates downward at 9.81m/s2, the pendulum will no longer oscillate.
