Name: Doppler ultrasound PROBLEM 4-8 points Ultrasound is the name we give to sound waves that have a higher frequency than 20 kHz, which is the maximum frequency our ears can respond to. For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). 2 points] (a) Ultrasound equipment for diagnostic imaging typically uses frequencies between 1...

A doppler fetal monitor is a hand-held ultrasound device that is used to detect a fetal heartbeat in prenatal care. The device works by measuring the speed of the fetus's ventricular wall and thereby tracking its heartrate. a. Suppose the fetus's ventricular wall moves back and forth in a pattern approximating simple harmonic motion with an amplitude of 1.7 mm and a frequency of 3.0 Hz. Find the maximum speed of the heart wall (in m/s) during this motion. Be...

A liquid of density 1.39 × 103 kg/m3 flows steadily through a pipe of varying diameter and height. At location 1 along the pipe the flow speed is 9.67 m/s and the pipe diameter is 11.5 cm. At location 2 the pipe diameter is 14.9 cm. At location 1 the pipe is 8.31 m higher than it is at location 2. Ignoring viscosity, calculate the difference between the fluid pressure at location 2 and the fluid pressure at location 1.
