Question

A physics department has a Foucault pendulum, a long-period pendulum suspended from the ceiling. The pendulum has an electric circuit that keeps it oscillating with a constant amplitude. When the circuit is turned off, the oscillation amplitude decreases by 50% in 34 minutes. What is the pendulum?s time constant? Express your answer using two significant figures. tau = 49 min Correct Part B How much additional time elapses before the amplitude decreases to 25% of its initial value? Express your answer using two significant figures. t1/4 = 19 min
