Suppose that a pendulum has a period of 4.0 s at earth’s surface. if the pendulum is taken to the moon, where the acceleration due to gravity is much less than on earth, will the pendulum’s period increase, decrease, or stay the same? explain your answer.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
