The middle c string on a piano is under a tension of 882 n


The middle C string on a piano is under a tension of 882 N. The period and wavelength of a wave on this string are 3.82 10-3 s and 1.26 m, respectively. Find the linear density of the string.

A wave traveling along the x axis is described mathematically by the equation y = 0.18 sin (8.4%u03C0t - 0.57%u03C0x), where y is the displacement (in meters), t is in seconds, andx is in meters. What is the speed of the wave?
