The number of vibrations n n per second of a nylon guitar string varies directly with the square root of the tension T T and inv
emmasim [6.3K]

Answer: T=40.96\ KgF

Step-by-step explanation:

We know that:

n: The number of vibrations per second of the nylon guitar string.

T: Tension.

L: The length of the string.

Since  n  varies directly with the square root of the  T and inversely with  L, the equation has the following form:

n=k*\frac{\sqrt{T} }{L}

Where "k" is the constant of variation.

Knowing that when n=15 and L=0.6, T=256, we can find the value of "k":

n=k*\frac{\sqrt{T} }{L}\\\\L*n=k\sqrt{T}\\\\\frac{L*n}{\sqrt{T}}=k\\\\k=\frac{(0.6)(15)}{\sqrt{256}}\\\\k=0.5625

Finally, in order to find the tension when the length is 0.3 meters and the number of vibrations is 12, you need to substitute these values and the value of "k" into n=k*\frac{\sqrt{T} }{L} and solve for T:

12=(0.5625)\frac{\sqrt{T} }{0.3}\\\\\frac{12(0.3)}{(0.5625)}=\sqrt{T}\\\\(6.4)^2=T\\\\T=40.96\ KgF
