Consider a loop in the standing wave created by two waves $($amplitude $5\mathrm{.}03$ mm and frequency $120$ Hz $)$ traveling in opposite directions along a string with length $4\mathrm{.}23$ m and mass $133$ g and under tension $37\mathrm{.}2$ N $.$ At what rate does energy enter the loop from $($a$)$ each side and $($b$)$ both sides? $($c$)$ What is the maximum kinetic energy of the string in the loop during its oscillation?
