1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...

1. On the diagram, mark with a star the position of the source
of the wave when it produced the first peak. With a square, mark
the position of the source of the wave when it produced its second
peak.
2. What is the distance between the star you’ve drawn and the
square you’ve drawn, in terms of previously-defined quantities?
(Hint: How long did it take the source to cover this distance, and
how quickly did it move?)

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...

Questions 2. [1] Wavefronts represent all points of the wave cycle. This statement is: correct, incorrect. [2] Wavefronts are: the forward sides of a wave, the backward sides of a wave, wavelengths, geometric shapes, points of both maximum and minimum values. [3] Sound propagates through the air. Wavefronts are drawn to show where the air undergoes a maximum compression. Halfway between two successive wavefronts, the air: undergoes a maximum compression returns to normal, undergoes a maximum expansion, somewhere between a...
