A sinusoidal transverse wave travels on a string. The string has length 8.00 m and mass 6.00 g. The wave speed is 30.0 m>s, and the wavelength is 0.200 m. (a) If the wave is to have an average power of 50.0 W, what must be the amplitude of the wave? (b) For this same string, if the amplitude and wavelength are the same as in part (a), what is the average power for the wave if the tension is increased such that the wave speed is doubled?

Dudaie 1 Physics II Chapter 20 Electric Potential and Electric Potential Energy 1. Electric Potential Energy and the Electric Potential a. Electrical and gravitational forces have many similarities (both conservative forces) i. As a result there is an electric potential energy (U), similar to the gravitational potential energy; since U is equivalent to W done. 1. Associated with electrical force a. ΔU = W = qEd ii. As far as electrical potential (V) is the electrical potential energy per charge 1. Δ
