1. What happens to the period of a mass-on-a-spring simple harmonic oscillator if the mass is doubled? What happens to the period if the spring constant is reduced by a factor of 3? How does the period depend on the amplitude of the oscillation?2. True or False: for a simple harmonic oscillator consisting of a mass on a spring, the period measured when the mass is hanging vertically is different than the period measured when the spring and mass are supported horizontally.
