Consta A 1.60-m string of weight 0.0128 N is tied to the ceiling at its upper end, and Part A the lower end supports a weight W . Neglect the very small variation in tension along the length of the string that is produced by the weight of the string. When you pluck the string slightly, the waves traveling up the string obey the equation How much time does it take a pulse to travel the full length of the string? y (x, t) = (8.50 mm) cos (172 rad . m x - 2730 rad . s-It) Assume that the tension of the string is constant and equal to W. ( EX ?? t = Submit Request Answer Part B What is the weight W ? W N Submit Request Answer Part C How many wavelengths are on the string at any instant of time? n= Submit Request
