1. The frequency of a simple harmonic oscillator is increased from 0.25 Hz to 0.60 Hz. What is the change in its period (final - initial)?

2. A 0.25-kilogram mass on a vertical spring oscillates at a frequency of 1.0 Hz. If a 0.45-kilogram mass were instead suspended from the same spring, what would be the frequency of oscillation?

3. A breeze sets in oscillation a lamp suspended from the ceiling. If the period is 2.5 s, what is the distance from the ceiling to the lamp at the lowest point? Assume the lamp acts as a simple pendulum.
