Answer :
Final answer:
The frequency of a 15-inch violin string is approximately 1.29 cycles per second.
Explanation:
To find the frequency of a 15-inch violin string, we can use the inverse variation formula:
f = k / l
Where f is the frequency, l is the length of the string, and k is the constant of variation. We can find the value of k using the given information:
350 = k / 18
To find the frequency of a 15-inch string, we substitute the values into the formula:
f = k / 15
Substituting the value of k from the previous equation, we have:
f = (350 / 18) / 15
Simplifying the equation gives:
f ≈ 1.29 cycles per second
