The amplitude of oscillation of a simple pendulum bob diminishes slowly because
energy is applied by some external agencies
frictional forces dissipate the energy of motion
the frequency of oscillation increases with the mass of the bob
the frequency of oscillation varies with time
the period of oscillation varies with time.
Correct answer is D
