A transverse wave in a wire with a linear density 2.35 g/m has the form y(x,t) = (1.4 cm)sin[(5.45 m(adsbygoogle = window.adsbygoogle || []).push({}); ^{-1})x−(6950 s^{-1})t].

What is the tension?

I took the A=.014m, k=5.45 /m, and [tex]\omega[/tex]=6950.

I used the formula for the max velocity = A[tex]\omega[/tex]

v=(.014)(6950)=97.3

Then I used the formula for the speed of a wave on a string v=[tex]\sqrt{\frac{F}{M/L}}[/tex].

97.3=[tex]\sqrt{\frac{F}{.00235}}[/tex]

And I got F=22.24813

This was not the correct answer. I would appreciate any advice.

I attempted to find the velocity of the pulse : (0.943s)(3.29m)(8)=24.81976
