Q2) A mercury thermometer having a time constant of 0.1 min is placed in a temperature bath of 100°F and allowed to equilibrium with the bath. At the initial time (t=0), the temperature of the bath begins to vary sinusoidally about its average temperature (100°F) with an amplitude of 2°F. If the frequency is (1i0/n ) cycle/min, find and plot the thermometer response (reading) on a graph paper.
