You want to create a pendulum clock (here on Earth) that will take 0.5 seconds to swing from one side to the other (which means it takes 1 second to go back and forth). How long should the pendulum be?
O 1m
O It depends on the mass of the pendulum bob
О 25 ст
9.8 m
6 ст
O It depends on the mass of the pendulum bob and the spring constant
О 50 сm
Continuing from the previous problem: You travel to Mars (where gravitational acceleration is 3.7 m/s-) and want to keep using your pendulum clock there (again, taking 0.5 seconds to swing from one side to the other). What adjustments do you need to
make?
O No adjustments are needed - the pendulum clock will still work properly on Mars.
It's impossible nothing you do can get this pendulum clock to work on Mars
Increase the mass of the pendulum bob
O Make the string shorter
Make the string longer
O Decrease the mass of the pendulum bob
O O O
