In the figure, a string, tied to a sinusoidal oscillator at P and running over a support at Q, is stretched by a block of mass m.Separation L= 1.2 m, linear density u = 1.6 g/m, and the oscillator frequency f= 200 Hz. The amplitude of the motion at P issmall enough for that point to be considered a node. A node also exists at Q.(a) What mass m allows the oscillator to set up the fourth harmonic on the string?(b) What standing wave mode, if any, can be set up if m 3 kg (Give 0 if the mass cannot set up a standing wave)?Oscillator(a) NumberUnits(b) NumberUnits

In the figure, a string, tied to a sinusoidal oscillator at P and running over a support at Q, is stretched by a block of mass m. Separation L = 0.8 m, linear density μ = 1.6 g/m, and the oscillator frequency f = 200 Hz. The amplitude of the motion at P is small enough for that point to be considered a node.

Observations of the water particle motions in a small amplitude wave system have resulted in major semiaxis=10cm and minor semiaxis=5cm for a total water depth of 1m. These observations apply for a particle whose mean position is at middepth. What are the wave height, period, and wavelength?
1(a) A damped simple harmonic oscillator has mass 2.0 kg, spring constant 50 N/m, and mechanical resistance 8.0 kg/s. The mass is initially released from rest with displacement 0.30 m from equilibrium. Determine the displacement x(t) as a function of time without assuming weak dissipation. Numerically compute all quantities. (b) The time for transients to become negligible is typically taken to be 5t, where the time constant t is the time required for the amplitude to decay to e-1 of its initial value. Taking the displacement amplitude to be approximately A = 0.30 m, (which holds for weak damping), determine the amplitude at time 5t. = Xoe¬Bt where xo
