Aiden and Michael are conducting an experiment with a pendulum apparatus. They have two pendulums, each with a "bob" at the end. "Bobs" a and b have masses of 20 g, while "bob" c has a mass of 10 g. Suppose Aiden and Michael pull "bobs" a and b back through an angle of 5°, how would their periods compare?

• The period of a is greater.

• The period of b is greater.

• The periods are equal.

• You can't tell because the lengths are different.

For the following question consider the pendulum apparatus shown below. "Bobs" a and b (the things hanging from the bottom) have masses of 20. g; "bob" c has a mass of 10. g. Suppose that you pulled "bobs" b and c back through an angle of 5°, how would their periods compare?

• The period of b is greater.
• The period of c is greater.
• The periods are equal.
• You can't tell because the lengths AND masses are different.
