If a simple pendulum has a significant amplitude (up to a factor of 1/e of original) only in the period between t=0 s to t=τ s, then τ may be called the average life of the pendulum. When the spherical Bob of the pendulum suffers a retardation (due to viscous drag) proportional to it’s velocity, with b as the constant of proportionality, the average life time of the pendulum is (assuming damping is small) in seconds

An ideal gas enclosed in a vertical cylindrical container supports a freely moving piston of mass M. The piston and cylinder have equal cross sectional area A. When the piston is in equilibrium, the volume of the gas is V0 and its pressure is P0. The piston is slightly displaced from the equilibrium position and released. Assuming that the system is completely isolated from its surrounding, the piston executes a simple harmonic motion with frequency
