A disc of radius a and mass m is pivoted at the rim and is set in small oscillation. If a simple pendulum have the same period as that of the disc, then the length of the simple pendulum should be

Two pendulum have time period T and $ \frac{5T}{4} $ they start SHM at the same time form the mean position. What will be the phase difference between them after the bigger pendulum completed one oscillation

An open pipe of length 33 cm resonates with frequency of 1000 Hz. If the speed of sound is $ 333\,m{{s}^{-1}}, $ then this frequency is

A heavy brass sphere is hung from a weightless inelastic spring and as a simple pendulum its time period of oscillation is T. When the sphere is immersed in a non-viscous liquid of density 1/10 that of brass, it will act as a simple pendulum of period :
