Both a mass-spring system and a simple pendulum have a period of 1.0 s. Both are taken to the moon in a lunar landing module. While they are inside the module on the surface of the moon,
A) the pendulum has a period longer than 1.0 s.
B) the mass-spring system has a period longer than 1.0 s.
C) both pendulum and mass-spring system have periods longer than 1.0 s.
D) the periods of both are unchanged.
E) one of them has a period shorter than 1 s.

The period of a pendulum depends on gravity, which is weaker on the moon, resulting in a longer period. The mass-spring system's period is independent of gravity, so it remains unchanged.
