Question 414299
The frequency or number (f) of vibration of a string under constant tension is inversely proportional to the length (l) of the string. If a string of 48 cm 
vibrates 192 cycles per second, find the the constant of proportionality and the number of vibrations per second a string of 32 cm will make.
----
f = k/L
---
Find "k" using "a string of 48 cm 
vibrates 192 cycles per second".
---
192 = k/48
k = 9216 (constant of proportionality)
---
Equation:
Find "the number of vibrations per second a string of 32 cm will make"
using y = 9216/L
y = 9216/32 = 288 vibrations per second
