1. Suppose that it takes a simple pendulum 1.2 seconds to swing from its leftmost point to its rightmost point. What is the period of the pendulum?
O A 0.6 S
OB. 1.2 s
O C. 245
O D.3.6 5
2. Suppose a simple pendulum consists of a 3.5 m string and a 0.3-kg bob, and its period is 3.75 s. What would be the period of the pendulum if the mass of the bob
were doubled? (Assume that gravity remains unchanged.)
O A. 1.875 S
OB.3.75 s
O C. 7.5 s
O D. Cannot be determined.
3. A pendulum with a string of length 2 m has a period of about 2.8 s. What would be the period of the pendulum if the length of the string were increased to 8 m?
O A. 1.45
OB. 5.6 s
O C. 11.25
O D. 44.8 5
4. A pendulum with a period of 1.8 s on Earth is moved to another planet. On the new planet, its period is 2.5 s. What can you conclude about this new planet?
O A. The force of gravity on the new planet is less than it is on Earth.
O B. The force of gravity on the new planet is the same as it is on Earth.
O C. The force of gravity on the new planet is greater than it is on Earth.
O D. There is not enough information to answer the question.
5. A simple pendulum swings with a period of 1.5 s. What would the period of the pendulum be if the length of its string were doubled, the mass of its bob were cut in
half, and the force of gravity were doubled?
O A. 0.5 S
O B. 1.5 s
O C.35
