Web1. It is the highest surface part of a wave. 1. The equation of certain traveling waves is y (x,t) = 0.0450 sin (25.12x - 37.68t - 0.523)where x and y are in meters, and t in seconds. Determine the following: (a) wavelength. 1- An observer counts 4 complete water waves passing by the end of a dock every 10 seconds. WebIn physics, the energy stored in a stretched spring is determined by the equation E = 1 2 kx2 where Eis the energy, kis a constant (the “spring constant”), and xrepresents the distance that the spring has been stretched. (a) Find a formula for dE dt in terms of k, x, and dx dt.
