A piano tuner sounds two strings simultaneously. One has been previously tuned to vibrate at 292.0 Hz. The tuner hears 4.0 beats per second. The tuner increases the tension on the as-yet untuned string, and now when they are played together the beat frequency is 0.9 s?1.
(a) What was the original frequency of the untuned string?
Hz
(b) By what percentage did the tuner increase the tension on that string?
%
