(Extrа Credit wоrth 5 pоints): A dоlphin is swimming towаrd а wall at the speed shown above. The dolphin emits a "chirp" at 55 kHz to echo-locate the wall. If this sound pulse is reflected back, what is the frequency of the echo received by the dolphin? Show and explain all work. (The bulk modulus of sea water is β = 2.31 x 109 N/m2 and the density of the seawater is ρ = 1.10 x 103 kg/m3.)
