One end of a horizontal string is attached to a small- amplitude mechanical 60.0-Hz oscillator. The string's mass per unit length is 3.2 x10-4kg/m. The string passes over a pulley, a distance l = 1.50 m away, and weights are hung from this end. Assume the string at the oscillator is a node, which is nearly true.

A string with a length of 1.65 m is fixed at both ends. It is then allowed to oscillate transversely such that there are 1 nodes between the ends, with an amplitude of 16.6 cm. What is the maximum transverse displacement of the string 0.967 m from one end? Please give answer in units of cm.
A bug on the surface of a pond is observed to move up and down a total vertical distance of 0.10 m , lowest to highest point, as a wave passes. What is the amplitude of the wave? If the amplitude increases to 0.20 m , by what factor does the bug's maximum kinetic energy change?
A person putting up power lines is told to stretch the wire between poles to a tension of about 800N. The person doesn't have a tension scale so they decide to measure the speed of a pulse created on the wire when they hit it with a wrench. The pulse travels from one pole 60m to another pole and back again in 2.6 s. The 60m long wire has a mass of 15kg. Should the wire be tightened or loosened? Explain how you decided. Thanks!

Expectant parents are thrilled to hear their unborn baby’s heartbeat, revealed by an ultrasonic motion detector. Suppose the fetus’s ventricular wall moves in simple harmonic motion with amplitude 1.80 mm and frequency 115 beats per minute. The motion detector in contact with the mother’s abdomen produces sound at precisely 2 MHz, which travels through tissue at 1.50 km/s. (a) Find the maximum linear speed of the heart wall. (b) Find the maximum frequency at which sound arrives at the wall of the baby’s heart. (c) Find the maximum frequency at which reflected sound is received by the motion detector. (By electronically “listening” for echoes at a frequency different from the broadcast frequency, the motion detector can produce beeps of audible sound in synchrony with the fetal heartbeat.)
