If a simple pendulum has significant amplitude (up to a factor of1//e of original) only in the period between `t-0s to t=tau s`, then `tau` may be called the average life of the pendulum. When the sphetical bob of the pendulum suffers a retardation (due to viscous drag) proportional to its velocity with b as the constant of propotional to average life time of the pendulum is (assuming damping is small) in seconds:

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

A simple pendulum is set into vibrations. The bob of the pendulum comes to rest after some time due t

A simple pendulum has a time period T. If the support and the pendulum fall freely, the time period will be
