A mass on an ideal spring and a simple pendulum have the same oscillation frequency on Earth. On Jupiter's moon Europa, the gravitational acceleration is about 1/9 that of Earth's. How would the frequency of the pendulum compare to the frequency of the mass-spring system if they were both oscillating on Europa? Group of answer choices The pendulum frequency would be 1/9 the mass-spring frequency. The pendulum frequency would be 1/3 the mass-spring frequency. The pendulum frequency would still be the same as the mass-spring frequency. The pendulum frequency would be 3 times the mass-spring frequency. The pendulum frequency would be 9 times the mass-spring frequency. None of the above are true
