A sound pulse emitted underwater reflects off a school of fish and is detected at the same place 0.17 s later (see the figure below). How far away are the fish? (Assume the water temperature is 20°C.)
Homework Answers
speed of sound in seawater at 20C , v = 1530 m/s
Distance of the ship = 0.5*total to and fro distance covered
= 0.5*v*t
= 0.5*1530*0.17
= 130 m answer

A sonic depth gauge is placed 3.2 m above the ground. An ultrasound pulse sent downward reflects off snow and reaches the device 0.015 seconds after it was emitted. The air temperature is −20°C. a)How far (in m) is the surface of the snow from the device? (Round your answer to at least three significant figures.) m b) How deep (in m) is the snow? m

A woman is swimming when she hears the underwater soundwave from an exploding ship across the harbor. She immediately lifts her head out of the water. The sound wave from the explosion propagating through the air reaches her 4.00 s later. How far away is the ship? Assume water temp is 25 C and air is 23 C The answer on this site is wrong and only accounts for the distance over the 4 seconds of time between receiving the...

Compare the distance traveled in 6.00 s as a given sound moves through (a) water at 25.0 degree C and (b) seawater at 25.0 degree C. A submarine sends a sonar signal, which returns from another ship 2.250 s later. How far away is the other ship if the speed of sound in seawater is 1, 530.0 m/s? A 520 Hz tone is sounded at the same time as a 516 Hz tone. How many beats per second will you...

The Heigth of a cliff relative to the ocean below is 57 m. Someone kicks a rock horizontally off of the cliff and hears the sound 4.62s later. a. How long does it take for the rock to hit the water? b. How far must the sound travel to get back to the cliff? assume that sound moves in a straight line with a speed of 343 m/s. c. Relative to the base of the cliff, where does the rock...

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...
