Apipe that is open at both ends and a tuning fork of frequency 240 hz are being used as a fancy new thermometer, albeit one that utilizes sound interference. at room temperature (20.0°c), the pipe's fundamental frequency and the tuning fork's frequency are identical and thus no beat frequency is heard between the two. when the temperature rises to 43.0°c, what beat frequency (in hz) should be heard?
