    Water drops are coming out of a tap as constant rate. A falling drop is observed at 4th 4^{\text{th~}} second after fall. Distance between that drop and next drop is 34.3 m34.3\text{ }m. Find the rate of water drops coming out of tap (drops/sec) [g=9.8 m/s2]\left\lbrack g = 9.8\text{ }m/s^{2} \right\rbrack

    A particle of mass 1 kg1\text{ }kg is hanging from a spring of force constant 100Nm−1100Nm^{- 1}. The mass is pulled slightly downward and released so that it executes free simple harmonic motion with time period TT. The time when the kinetic energy and potential energy of the system will become equal, is Tx\frac{T}{x}. The value of xx is

    The pulley shown in figure is made using a thin rim and two rods of length equal to diameter of the rim. The rim and each rod have a mass of M . Two blocks of mass of M and m are attached to two ends of a light string passing over the pulley, which is hinged to rotate freely in vertical plane about its centre. The magnitudes of the acceleration experienced by the blocks is ____\_\_\_\_ (assume no slipping of string on pulley.)
