With what tension must a rope with length 2.30 mm and mass 0.105 kgkg be stretched for transverse waves of frequency 36.0 hzhz to have a wavelength of 0.790 mm?

Tension must a rope be stretched is 36.8828 N

Explanation:

Wave speed in term of wavelength:

Where:

f is the frequency

is the wavelength

Now:

Wave speed in term of tension force and mass per unit length

                         Eq (1)

Where:

F is the tension force

Since   is calculated above.On rearranging Eq (1) we will get:

Tension must a rope be stretched is 36.8828 N

if you answer my question i will answer yours

thermal energy is the answer
