Explanation:

The complete question is:

A transverse wave produced near one end of an extremely long vibrating string is described by the equation below. (Ignore wave reflections from the other end of the string, which is extremely far ahead.) The linear density of this string is 0.0073 kg/m. What must be the tension applied to this string?

y(x,t)=.0321m * sin (2.05x-524t + pi/4)

To find the tension in the string you use the formula for the speed of the wave in a string:

T: tension

mu: linear density of the string = 0.0073kg/m

Then, it is necessary to calculate v. This is made by using information from the wave equation:

by replacing the value of v in (1), and doing T the subject of the formula you obtain:

hence, the tension applied is between 450N and 500N

1/0.14nm = 10^10/1.4 a lot
