3. During maneuvers in the northern Pacific Ocean, two attack submarines are heading straight for each other on a collision course. The first sub is traveling at 30 km/hr, while the second submarine is traveling at 75 km/hr. The first sub sends out a sonar pulse of 1000 Hz which is picked up by the second sub. What is the frequency of the sonar pulse detected by the second sub? The speed of sound in sea water is 1520 m/s. v, = 30 km/hr v, = 75 km/hr

1) A student standing in a canyon yells "echo", and her voice produces a sound wave of frequency of f = 0.65 kHz. The echo takes t = 3.9 s to return to the student. Assume the speed of sound through the atmosphere at this location is v = 325 m/s. a) What is the wavelength of the sound wave in meters? b) Input an expression for the distance, d, the canyon wall is from the student. c) How many wavelengths are between the student and the wall?
You are standing on a train station platform as a train goes by close to you. As the train approaches, you hear the whistle sound at a frequency of f1 = 94 Hz. As the train recedes, you hear the whistle sound at a frequency of f2 = 77 Hz. Take the speed of sound in air to be v = 340 m/s. Find an equation for the speed of the sound source vs, in this case it is the speed of the train. Express your answer in terms of f1, f2, and v. Find the numeric value, in meters per second, for the speed of the train. Find an equation for the frequency of the train whistle fs ("s" is for "source") that you would hear if the train were not moving. Express your answer in terms of f1, f2, and v.
A hammer taps on the end of a 4.0 m long metal bar at room temp. A microphone on the other end of the bar picks up two pulses of sound, one that travels through the metal and one that travels through the air. The pulses are separated in time by 11 ms. a. what is the speed of sound in theis metal? solved: v= 6060m/s. b. if the bar was twice as long, what would be the time difference? delta t = (in ms)

One day when the speed of sound in air is 343 m/s, a fire truck traveling at vs = 27 m/s has a siren which produces a frequency of fs = 435 Hz. vS = 27 m/sf = 435 Hz A. What frequency (in Hertz) does the driver of the truck hear? B. What frequency (in Hertz) does an observer hear when the truck is moving away?
The speed of sound is temperature dependent and can be determined by the formula: v(sound) = 331 + 0.6 T(C), where v is the speed of sound in m/s and T is temperature in degrees C. If a sound wave is determined to have a frequency of 1,000 Hz and a wavelength of 35 cm. a) What is the speed of this wave? b) Use the given formula to determine the temperature of the air? c) Based on your temperature result, how would you categorize the air as WARM or COLD?
