I need help with parts e and f please. I know that a) 0.288m, b) 180 m/s, c) 162 N, and d) 125Hz. 1. A string of length L = 0.720 m is fixed at both ends. It oscillates in a five-loop standing wavepattern at a frequency f, = 625 Hz . The mass of the string is m = 3.60 g .a. What is the wavelength of the five-loop pattern (the 5th harmonic), 15, for this string?b. What is the wave speed, v, on the string?c. What is the tension, 7 for this string?d. What frequency, f, is needed to excite the first harmonic?e. For a n = 3 standing wave on this string, what is the maximum transverse velocity,Max(u(x,t)) , at one of the anti-nodes if one of the two traveling waves that make upthe standing wave has an amplitude y, =1.75mm ?f. Sketch the envelope of oscillations for the 1$t through 4th harmonics (the shape of thewave function when cos(@ t) =1 and when cos(@t) =-1) and label the nodes (withthe letter N) and antinodes (with the letter A) on your sketch.
