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

A string with a mass of 0.02 kg and a length of 2 meters is stretched between two fixed points. The tension in the string is 100 N. Calculate the speed of a transverse wave traveling through the string. (Note: Assume the string is massless, and there is no damping or energy loss during wave propagation.)

The depth to an unusual layer of rock is to be determined at a particular place by bouncing an artificially generated seismic wave off it and receiving the echo at the surface. When this is done, the depth is given by the equation, h = (1/2) v t, in which h is the depth, v is the average velocity of the seismic wave, and t is the time that it takes for the wave to go down to the rock layer and return to the surface. If t = 0.350 +/- 0.10, and v = 2,000 +/- 10. meters per second, what is the possible error in the depth. (Show your work, and remember to express your results in the correct number of significant figures.)

A string has a mass attached to it as shown in the figure. The length of the entire string is 2.4 m, and its mass is 12 gram. The hanging mass attached to the string is M = 4 kg. 1/4 of the length of the string is in the hanging part (vertical) and 3/4 is parallel to the table. The string in the horizontal part is plucked, and standing waves are observed in the third harmonic. Calculate the frequency of vibrations in the string (in Hz), and what will be the speed of the wave in the string? Enter the speed in m/s as your answer in canvas. |M kg
