Question 3 (1 points) (#513992) {Transverse Standing Waves} A string with a length of 4.51 m is held under a constant tension. The string has a linear mass density of u = 0.000784 kg/m. Two resonant frequencies of the string are 400 Hz and 480 Hz. There are no resonant frequencies between the two frequencies. What is the tension in the string? Please enter a numerical answer below.

The string is run over a frictionless pulley and the other end of the string is attached to a stationary hanging mass. The distance between the wall and the pulley is 0.588 meters, When the mass on the hook is 22.7 kg, the horizontal portion of the string oscillates with a fundamental frequency of 261.6 Hz (the same frequency as the middle C note on a piano). Calculate the linear mass density of the string. Please enter a numerical answer below.
