Aultrasonic wave at 8x10^4 hz is emitted into a vien where the speed of sound in blood is 1570 m/s. the wave reflects off the red blood cells moving towards the stationary receiver, if the frequency of the4 returning signal is 8.002x10^4 hz, what is the speed of blood flow?

0.392 m/s

Explanation:

The Doppler shift equation is:

Where:

is the actual frequency of the sound wave

is the "observed" frequency

is the speed of sound

is the velocity of the observer, which is stationary

is the velocity of the source, which are the red blood cells

Isolating :

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

nah.   i'm just sleepy.
