(3) A harmonica makes sounds when a reed inside of it vibrates back and forth. We canconsider this to the same as a string with mass 16.5g that is fixed at both ends. The reed isexperiencing 639N of tension.(a) This particular harmonica is in the key of D# and it can emit as a fundamentalfrequency f = 311.13H z. What is the length of the reed?(b) What is the n =(c) A person decides to produce the fundamental frequency on the harmonica in a room20°C while rolling around in their favorite chair at 8.19m/s. They hear the echo oftheir playing off the wall that they are moving away from. What is the frequency of the echoheard by the harmonica player?(d) When an observer is 6.79m away from the harmonica player, the sound intensity levelis 86.6dB. What is the sound intensity level of the music when the observer is 41.6m awayfrom the harmonica player?3 harmonic for this reed?at T

A dinosaur called Parasaurolophus is a dinosaur (looks like a dinosaur with a single horn) thathas a hollow horn crest on its head. The 1.5 m long hollow tub inside of this crest hadconnections to the throat, leading some paleontologists to guess that the tube was used as aresonant chamber in vocalization. If you model this system as an open-closed system, what arethe first three resonant frequencies at 85 degrees F?
