Answer:

To determine the tension in the string, we can use the wave equation for a vibrating string:

v = √(F/μ)

Here:

v is the velocity of the wave

F is the tension in the string

μ is the linear mass density of the string

We are given the frequency of the wave, f = 329.6 Hz, and the linear mass density of the string, μ = 0.00526 kg/m.

The velocity of the wave can be calculated using the formula:

v = λf

Here:

v is the velocity of the wave

λ is the wavelength of the wave

f is the frequency of the wave

In this case, the frequency is given as 329.6 Hz. However, we need to find the wavelength first. The wavelength can be determined using the formula:

λ = v/f

Now we can substitute the values and solve for λ:

λ = v/f λ = v/329.6

We also know that the velocity of the wave is given by:

v = √(F/μ)

Substituting this into the previous equation:

λ = (√(F/μ)) / 329.6

Now we can rearrange the equation to solve for F:

F/μ = (λ × 329.6)²

F = μ × (λ × 329.6)²

Since we know μ=0.00526 kg/min, by Substituting we get

F = 0.00526 * (λ * 329.6)²N

Please note that the above calculations assume that the string is vibrating in its fundamental mode (the first harmonic). If the string is vibrating in a different mode (e.g., second harmonic, third harmonic), the calculations would differ.

Since the exact length or harmonic of the vibrating string is not provided in the question, we would need additional information to determine the tension accurately.
