4. A 10.0 m long string has a mass of 20.0 g. a. What speed will a wave pulse move along this string if is under 50.0 N of tension? b. Suppose this string is cut to a length and fixed between two points placed with 50.0 N of tension. A wave pulse is sent along the string and takes 0.030s to move from one end to the other. What is the length of the string? C. What is the fundamental frequency of the string (from part b)? d. Sketch the standing wave pattern for the fourth harmonic of the string (from part b). Calculate the wavelength of this mode.
