While tuning a string to the note c at 523 hz, a piano tuner hears 2.00 beats/s between a reference oscillator and the string.
(a) what are the possible frequencies of the string?
(b) when she bghtens the string, she hears 3.00 beats/s. what is the frequency of the string now?
(c) assuming the string is now tuned to 526 hz, by what percentage should she change the tension in the string to bring it into tune at 523 hz?
