Standing waves are produced by superposition of the following waves: y1(x, t) = 0.2sin π(2t – x) and y2(x, t) = 0.2sin π(2t + x) (i) Obtain the resultant displacement of the particle at x at time t. (ii) For what value of x will the displacement be zero at all times? (iii) What is the distance between two nearest values of x at which displacements are zero? Is this distance related to the wavelength of the standing wave?

A body of mass 0.2 kg is suspended from a spring of force constant 80 Nm^-1. A damping force is acting on the system for which γ = 4 Nsm^-1. Write down the equation of motion of the system and calculate the period of its oscillations. Now a harmonic force F =10cos10t is applied. Calculate a and θ when the steady state response is given by a cos(ωt − θ).
