The acceleration due to gravity on the moon is 1/6 that on the earth. If you wanted a pendulum clock to tell the time on the moon the same as it does on the earth (i.e., have the same period), If the pendulum was originally 24.0 cm long on the earth, how long should it be on the moon? a. 16 cm b. 10 cm c. 8cm d. 144 cm e. None of the above

A siren starting from rest slides down a tall frictionless hill towards a biker. The biker travels at a constant velocity while the siren approaches him from behind. At the bottom of the hill, the siren will be traveling faster than the biker. How will the frequency of the siren change over time? It will start off lower than the original frequency of the siren, and increase in frequency'until it is higher than the original. It will be exactly the same original frequency emitted by the siren, for the entire time the siren rolls down the hill. It will be lower than the original frequency emitted by the siren, for the entire time the siren rolls down the hill. It will be higher than the same original frequency emitted by the siren, for the entire time the siren rolls down the hill.
