Two pendulums are in simple harmonic motion.  Pendulum A is longer than pendulum B.  Pendulum A has a larger mass than B.  The period of pendulum A is

• longer than pendulum B
• shorter than pendulum B
• the same as pendulum B
• not enough information

Two pipes of different length are resonating at their fundamental frequencies.  Which is true?

• The speed of sound is slower in the longer tube
• The speed of sound is slower in the shorter tube
• The frequency of the longer tube is higher
• The frequency of the shorter tube is higher

A pendulum's period is initially t. Changes are made to the system so that the new period is 2t. What may have been changed?

• The length of the pendulum was increased by a factor of 2.

• The pendulum was moved to a planet with 2 times the mass of Earth.

• The length of the pendulum was increased by a factor of 4.

• The pendulum was moved to a planet with 4 times the mass of earth.
