A rope, under a tension of 139 N and fixed at both ends, oscillates in a second-harmonic standing wave pattern. The displacement of the rope is given by $$y = (0.147 \text{ m})\sin(\frac{\pi x}{5.00})\sin(11.0\pi t),$$ where $x = 0$ at one end of the rope, $x$ is in meters, and $t$ is in seconds. What are (a) the length of the rope, (b) the speed of the waves on the rope, and (c) the mass of the rope? (d) If the rope oscillates in a third-harmonic standing wave pattern, what will be the period of oscillation?
