Grandfather clocks are designed to have a period of exactly two seconds. Determine the following quantities for a perfect grandfather clock: 1. Length of the pendulum: ___cm 2. Frequency of the pendulum: ___Hz If this grandfather clock were brought to Neptune, where g=11.15 m s2 , would you need to make the pendulum longer or shorter to keep proper time? a. The pendulum would need to be shorter b. The pendulum would not need to change length c. The pendulum would need to be longer Suppose a different grandfather clock with a pendulum of length 137.00cm is brought on the next space shuttle to the moon. What would the frequency of the pendulum be when the astronauts take the pendulum onto the Moon, which has gravity of 1.62 m s2 ? a. 1.0874 Hz b. 2.3480 Hz c. 0.0173 Hz d. 6.8325 Hz e. 0.1731 Hz
