Please write your work and answers on a sheet of paper that you can turn in. Thanks!
1. What factor(s) does the period of a pendulum depend on?
2. Draw the approximate shape of a graph of period vs. length for a pendulum.
3. The equation we've seen in class is the period of a "simple" pendulum. What do you suppose makes our pendulums "simple"?
4. Calculate the period of a 5-m long pendulum.
5. If the pendulum in #4 above were taken to Mars, where the gravity is roughly 40% Earth's gravity, how would the period be different (if at all)?
6. Consider a 261.6 Hz sound wave (this is approximately the note 'middle C'). Assume that the speed of sound at sea level is 340 m/s.
a. What is the wavelength of this sound wave?
b. Do you think the wavelength of this sound wave would be different on the Moon?
