An ultrasound transducer used to measure the speed of blood cells is oriented at an angle of 45 degrees to the direction of the blood flow. if the frequency of the sound emitted by the transducer is 1.5 Mhz and the doppler shift is 268Hz, calculate the speed of blood cells. Take the speed of the sound in the blood as 1572 m/s. (please show how u did it :)
