What is the speed of sound in water if the wavelength of ultrasound with a frequency of 2.80 x 105 Hz is 0.510 cm? How long would it take this sound wave to travel to a dolphin 3.00 km away?

Use the following information for determining sound intensity. The number of decibels ß of a sound with an intensity of I watts per square meter is given by B = 10 log(I/I0), where Io is an intensity of 10-12 watt per square meter, corresponding roughly to the faintest sound that can be heard by the human ear. Find the number of decibels ß of the sound. (a) I = 102 watt per m2 (jet at 30 meters) dB (b) I = 10-2 watt per m2 (siren at 30 meters) dB (c) I = 10-10 watt per m2 (quiet room) dB (d) I = 100 watt per m2 (threshold of pain) dB

A sound wave in a solid has a frequency of 12.0 kHz and a wavelength of 0.333 m. What would be the wave speed, and how much faster is this speed than the speed of sound in air? (The speed of sound in air is 344 m/s.)

A giant sea monster chases a deep sea submarine near the bottom of the North Atlantic.  The submarine is moving at 30 m/s.  The sea monster sends out a sonar signal (sound) of frequency 1000 Hz.  The signal received by the sub has a frequency of 985 Hz.  The speed of sound in saltwater is 1530 m/s.  Determine the speed of the sea monster _________________ and if the sub is in trouble (yes or no)___________________

A sound wave in a solid has a frequency of 60.0 kHz and a wavelength of 0.333 m. What would be the wave speed, and how much faster is the speed than the speed of sound in air? (The speed of sound in air is 344 m/s.) speed of sound in solid  speed of sound in solid speed of sound in air

There was an accident and NASA engineers are trying to sort out where two of their Mars Rovers, Tango and Foxtrot, have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at it's landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at it's landing site, where has each rover landed?

An organ pipe that is 1.75 m long and open at both ends produces sound of frequency 303 Hz when resonating in its second overtone. What is the speed of sound in the room? m/s
