WebSolution. Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string. Weba) Power is a rate of energy transfer (or the rate of energy transfer per second) b) 1 watt is 1 joule of energy transferred per second c) energy transfer = power x time, or E = Pt Energy transfer is in joules (J), power is in watts (W) and time is in seconds (s) 5) 1,200 J 6) 108 kJ 7) a) 5,400 seconds b) 3 W 8) 17 minutes 9)
