Say that a string, with linear mass density of 0.020 kg/m, is connected to a mechanical oscillator on the left end and sent over a frictionless pulley on the right, as shown. A mass of 1.50 kg is hung from the string, and the mass remains stationary. The length of the string between the oscillator and the pulley, which act as fixed endpoints for a standing wave, is 3.0 meters. What would be the frequency of the 3rd mode (n=3)? M 13.6 Hz O 27.1 Hz O 4.33 Hz 10.0 Hz 9.04 Hz
