PHYS2014 Fall 2010 Benton OSU Physics Dept. 11-1 Physics 2014: General Physics I Homework Assignment 11 Due: Friday, 3 December 2009 at the beginning of your Recitation session. 1. A stone of mass M = 1.3 kg is suspended from a string on a 30 ° incline as shown above. If the length of the string is 75 cm and the mass of the string is 4 g, how long would it take a transverse wave to travel from one end of the string to the other? 2. What are the three lowest frequencies for standing waves on a wire that is 10 m long, has a mass of 0.10 kg, is stretched under a tension of 250 N, and is fixed at both ends? 3. A wave travels along the x -axis in the direction of decreasing x along a cable having a linear mass density of μ = 50.0 g/cm and under a tension of T = 60.0 N. The frequency of the wave is f = 20.0 Hz. a) Find the wavelength and period of this wave. b) If the amplitude of the wave is 1.5 cm, find the equation for the wave as a function of x and time, t . c) Determine the average power of the wave. 4. Like most dolphins, “Sparky the Wonder Dolphin” uses echolocation (or sonar) by emitting
