We consider air as a fluid. The density at 15.0°C is 1.225 mg/cm3 , and the bulk modulus is 1.416×105 Pa. In these conditions, a bat flies toward a wall, emitting a steady sound of frequency 1.70 kHz. This bat hears its own sound plus the sound reflected by the wall. a) Calculate the speed of sound in air at 15.0°C? b) How fast should the bat fly in order to hear a beat f
