1) A cable made from a metal of density 8850 kG/cubic meter, and whose cross sectional area is 9.6 cubic mm is pulled to a stress of 103.4 Newtons. One end of the string is oscillated with a frequency 480.1 Hertz. The wavelength of the wave on the string (in meters) is
T=f^2 * linear mass density * wavelength^2
T=103.4 Newtons
linear mass density = 8850 kG/cubic meter
f=480.1 Hertz
so, I plug all those in and got 2.25E-4
but the correct answer is 7.27E-2
The question gave a cross sectional area. How does that relate to the wavelength?
