) A dolphin swims towards you at 40km/h chirping at 1000kHz. What Doppler-shifted frequency do you...
Question: A diver underwater sees a dolphin swimming towards him with a speed of 7.257 m/s. The diver gets excited and swims towards the dolphin with a speed of 11.994 m/s. The dolphin sees the diver and emits a call with a frequency of 22.73 kHz. Assume that the speed of sound through the water is 1521 m/s. Part 1) What frequency does the diver detect coming from the dolphin? f= kHz Part 2) The sound is reflected off the...
A motorcyclist is moving 24.5 m/s towards a stationary siren, and hears a 894 Hz sound. What is the frequency of the siren when the cyclist is stationary? A motorcyclist is moving 24.5 m/s toward a stationary siren, and hears an 894 Hz sound. What is the frequency of the siren when the cyclist is stationary? (Hint: 894 Hz is the Doppler-shifted frequency.) (Speed of sound 343 m/s) (Unit Hz) nter
Hints: Doppler Effect: 5. Another Brick in the Wall 1604 You are in a car that is heading towards a brick wall at a speed of 32 m/s (72 mph). You know that the wall has a resonant frequency of 605 Hz, and that if a continuous sound wave at this frequency hits the wall, it will fall down.

Solve the following Doppler Shift problems. Show your work. 1. A concert goer hurries down the aisle to her seat at a speed of 3 m/s. What frequency does she hear when the note A (440 Hz) is played by an instrument of stage if the speed of sound in the concert hall is 343 m/s? 2. A fire engine with a 600 Hz siren approaches then passes a stationary observer. If the engine is traveling at 20 m/s on...
I know how to do the first 3 parts. Need last 3 parts of the question. Posted whole thing for reference. Thanks! a) A 1 meter long guitar string of linear mass density 2g/m3 is put under tension until it resonates with a fundamental frequency of 440 Hz. Determine the tension that produces this fundamental frequency. Also determine the other of the first four harmonic frequencies and draw diagrams illustrating what each of these oscillations looks like on the string....

Question: To demonstrate the Doppler effect, your lecturer puts a tone generator playing a 564 Hz tone in a ball tied to a rope and swings it around. As it swings, you hear a maximum frequency of 578 Hz from your seat in the middle of the large lecture hall. Assume the speed of sound through the air is 336 m/s. Part 1) What speed is the ball moving at? v = 8.14 m/s Your last answer was interpreted as...
4. In one of the original Doppler experiments, a tuba was played on a train at a speed of 60 km/h, at a constant frequency of 75 Hz, while a second identical tuba played the same note on the platiorm at the railway station. Assume the observer is standing still on the platiorm on a day when the outside air temperature is 20° C a. What is the effect that is observed regardless of any sound from the tuba at...
A friend of yours is loudly singing a single note at 400 Hz while racing toward you at 26.8 m/s on a day when the speed of sound is 347 m/s . What frequency do you hear? What frequency does your friend hear if you suddenly start singing at 400 Hz ?
12.3 (a) In which of these scenarios do you hear a higher pitched sound? Explain speed vo you at speed vo (i) A train with its horn sounding is stationary and you move directly towards it with a (ii) You stationary and the same train is sounding its horn as it moves directly towards (b) What is the difference in pitch between the above two scenarios if vo-30 m/s, the frequency of the train horn is 800 Hz and the...
