105. •Medical An ultrasound machine can measure blood flow speeds. Assume the machine emits acoustic energy at a frequency of 2.0 MHz, and the speed of the wave in human tissue is taken to be 1500 m/s. What is the beat frequency between the transmitted and reflected waves if blood is flowing in large arteries at 0.020 m/s directly away from the sound source?
