Two different simple harmonic oscillators have the samenatural frequency (f=8.00 Hz) when they are on the surface of theEarth. The first oscillator is a pendulum, the second is a verticalspring and mass. If both systems are moved to the surface of themoon (g=1.67 m/s2),
1. What is the new frequency of the vertical spring and mass?
2. Calculate the new frequency of the pendulum.
