Aphysics 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 37 minutes.
a. what is the pendulum's time constant?
b. how much additional time elapses before the amplitude decreases to 25% of its initial value?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
