A simple pendulum and a mass oscillating on an ideal spring both have period T in an elevator at rest.If the elevator now moves downward at a uniform 2 m/s,what is true about the periods of these two systems?
A)Both periods would remain the same.
B)Both periods would increase.
C)Both periods would decrease.
D)The period of the pendulum would increase but the period of the spring would stay the same.
E)The period of the pendulum would decrease but the period of the spring would stay the same.

The period of a simple pendulum depends on the length of the pendulum and the acceleration due to gravity, neither of which changes in an elevator moving downward at a constant speed. The period of a mass oscillating on an ideal spring depends on the mass and the spring constant, which also do not change in this scenario. Therefore, both periods remain the same.
