(a) Expectant parents are thrilled to hear their unborn baby's heartbeat, revealed by an ultrasonic motion detector. Suppose the fetus's ventricular wall moves in simple harmonic motion with an amplitude of 1.70mm and a frequency of 130. per minute. Calculate the maximum linear speed of the heart wall. Suppose the motion detector in contact with the mother's abdomen produces sound at 1910000Hz, which travels through tissue at 1.50km/s. (b) Calculate the maximum frequency at which the sound would be perceived at the wall of the baby's heart. (c) Calculate the maximum frequency at which reflected sound is received by the motion detector. (By electronically "listening" for echoes at a frequency different from the broadcast frequency, the motion detector can produce beeps of audible sound in synchronization with the fetal heartbeat.)

A rope has length L equals to 3.0 m and is fixed to both ends. What is the wave length pattern for the 5th harmonic?

PRACTICE ANOTHEI The overall length of a piccolo is 31.0 cm. The resonating air column is open at both ends. (a) Find the frequency of the lowest note a piccolo can sound. (Assume that the speed of sound in air is 343 m/s.) Hz (b) Opening holes in the side of a piccolo effectively shortens the length of the resonant column. Assume the highest note antinodes for this mode of vibration. piccolo can sound is 4 500 Hz. Find the distance between adjacent mm Need Help? Watch It
