1. What is the frequency of a pendulum, whose normal period is T, when it is in an elevator in free fall? Hint 1: What is the apparent value of g in this situation? Consider what a scale would show your weight to be if you were in free fall. Hint 2: Another way to think about this: how many times will a pendulum oscillate (frequency) if you cut the string?

a. 0

b. 1/T

c. T

d. infinite
