The velocity y of a particle in a time t is given by the equation
y = 10 + 2t\(^2\)
Find the instantaneous acceleration after 5 seconds
A sonometer wire is vibrating at frequency fo. If the tension in the wire is doubled while the length and the mass per unit length are kept constant, the new frequency of vibration is
A transverse wave is applied to a string whose mass per unit length is 3 x 10-2kgm-1. If the string is under a tension 12N, the speed of the propagation of the wave is
