Unless otherwise indicated, for problems in this section, assume that the speed of sound through human tissues is 1540 m/s.
A diagnostic ultrasound echo is reflected from moving blood and returns with a frequency 500 Hz higher than its original 2.00 MHz. What is the velocity of the blood? (Assume that the frequency of 2.00 MHz is accurate to seven significant figures and 500 Hz is accurate to three significant figures.)
The blood’s speed is 1539.23 m/s
