Q4) Doppler uses ultrasound to measure blood flow velocities. Suppose that the device emits sound at a frequency of 3.2MHz, and that the speed of sound in human tissue is m/s 1540). What is the expected pulse rate if blood is flowing in the arteries of the large leg at a speed of 3 cm/s away from the source of the sound? 1260Hz 126Hz 12.6Hz O 12.6KHz 126KHZ O 1260KHz 1.26MHz
