PHYS 1051 Midterm: PHYS 1051 Fall 2011 Term Test 1
Document Summary
Instructions: there are four questions, each consisting of short theory part and a problem solving part. Answer all the questions: the amount of points awarded for each part in the bracket next to it, please use three signi cant gures in all calculations, relax. A)sketch a graph showing the restoring force f of an ideal spring as a function of displace- ment x of the spring from its unstrained length. [2 points: a mass m = 0. 180 kg is attached to a spring with spring constant k. the spring is then compressed to x = +4. 50 cm and released, oscillating around the equilibrium of x = 0. 00 cm. [2 points] b)a transverse wave on a string is described by the wave function y(x, t) = (0. 120 m) sin( [3 points: calculate the tension on the string. Question iii: a c- ute with all this holes covered (so with openings only at the ends) plays a middle.
