Simple Pendulum: A pendulum of length L is suspended from the ceiling of an elevator. When the elevator is at rest the period of the pendulum is T. How would the period of the pendulum change if the supporting chain were to break, putting the elevator into freefall?

A. The period does not change.
B. The period increases slightly.
C. The period decreases slightly.
D. The period becomes zero.
E. The period becomes infinite because the pendulum would not swing.

Light passes through three ideal polarizing sheets. Unpolarized light enters the first sheet and the resultant vertically polarized beam continues through the second sheet and third sheet

The second sheet has its transmission axis at 50° with respect to the first sheet, and the third sheet is at 70° with respect to the first sheet. (a) What percent of the original intensity emerges from filter #1? (b) What percent of the original intensity emerges from filter #2? (c) What percent of the original intensity emerges from filter #3?
