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...

7) A sound wave having a frequency f travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving towards the sound receiver as the heart beats. The reflected sound is then mixed with the transmitted sound resulting in beating signal, where the number of beats (not being the heart beats of the baby) per second in this signal turns out to be b. The speed of sound...

7. 0.41 points Tipler8 2.P057 My Notes Ask Your Teacher A submarine can use sonar (sound traveling through water) to determine its distance from other objects. The time between the emission of a sound pulse (a "ping") and the detection of its echo can be used to determine such distances. Alternatively, by measuring the time between successive echo receptions of a regularly timed set of pings, the submarine's speed may be determined by comparing the time between pings....

10. A sound is transmitted through air (density 1.20 kg/m2) at a velocity of 345 m/s and then through water (density 1.00 x 10 kg/m2) at a velocity of 1495 m/s. Calculate the acoustic impedance in each medium. What fraction of the sound's intensity will be reflected and transmitted in passing from air to water? What fractions would be reflected and transmitted if the sound traveled from water to air?

A sound wave with a frequency of 250 Hz is transmitted through air at 25° C (298.2K) The specific gas constant for air is 287 J/kg K, and tne specific heat ratio is γ = 1.40. Determine (i) The speed of sound, (i) The wavelength, (ii) The wave number, (iv) The angular frequency for this condition. The noise level measured at a particular location in a factory with a noisy machine operating nearby is 92 dB(A). When the machine is...

I have everything but E Submarine A travels horizontally at 13.0 m/s through ocean water. It emits a sonar signal of frequency f = 5.22 103 Hz. in the forward direction. Submarine B is in front of submarine A and traveling at 4.5 m/s relative to the water in the same direction as submarine A. A crewman in submarine B uses his equipment to detect the sound waves ("pings") from submarine A. We wish to determine what is heard by...

A sound wave a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.78 m. Concepts: The diffraction angle for a wave emerging through a circular opening is given by sin(theta) = 1.22 /D, where is the wavelength of the sound and D is the diameter of the opening. What is meant by the diffraction angle? the angle that the sound wave bends away from the center before passing through the opening the location of...

A simplified model of a submarine sonar assumes that all objects echoing the signal are moving either straight toward or straight away from the detector. What is direction and magnitude of the velocity of a whale if a detector receives a signal of 26,730 Hz while the emitted signal had a frequency of 27,200 Hz. Consider the speed of sound in water vw = 1,500 m/s. Select one: a. whale moves toward detector with a velocity of 10.8 m/s b....
