Problema Solution

The rate of vibration of a sting under constant tension varies inversely with the length of the string. If a string is 48 inches long and vibrates 256 times per second, what is the length of the string that vibrates 576 times per sencond?

Answer provided by our tutors

answer r=k/l

=>256=k/48

=>k=256*48

so for 576 we have l=256*48/576=256/12=21.33
