13)
A sinusoidal wave on a string is described by the wave function y(x,t) = 0.02 sin(30x -
400t)
(SI units). If the string's linear mass density is µ = 0.005 kg/m, then the transmitted power is:
(a) 1.3 W
(b) 2.13 W
(c) 4.48 W
(d)5.54 W
The following given is for questions 14 and 15:
Consider a taut string of linear mass density u = 0. 04 kg/m, stretched by a mass m as shown in
the figure below.
Vibrator
The propagating wave produced by a vibrator on one end of the string is represented by the wave
function:
y(x, t) = 0.05 sin(3ax
- 18nt + p)
where x and y are in meters and t is in seconds.
