- A noisy factory machine produces a sound intensity of 1.00 x 10-5 W/m2 when measured 10 m from the machine. Assume that the sound spreads out uniformly into 3 dimensions for this set of questions. What is the sound power output of the machine? (Give your answer in mW.) What is the decibel level of the machine at 10 m? At what distance is the decibel level equal to 55 dB? (Give your answer in m.)A source emits sound uniformly in all directions. There are no reflections of the sound. At a distance of 12 m from the source, the intensity of the sound is 4.2 x 10-³ W/m². What is the total sound power P emitted by the source? P = Number 1 UnitsSuppose that a public address system emits sound uniformly in all directions and that there are no reflections. The intensity at a location 27 m away from the sound source is 3.0 X 10-4 W/m2. What is the intensity at a spot that is 80 m away?

What is the maximum displacement of air molecules at that location? Assume the density of air is 1.20 kg/m³ and that the source produces spherical wave fronts. Express the displacement as a number having the units of mirco meters. 1 micro meter = 1 x 10-6 m.

- The depth to an unusual layer of rock is to be determined at a particular place by bouncing an artificially generated seismic wave off it and receiving the echo at the surface. When this is done, the depth is given by the equation, h = (1/2) v t, in which h is the depth, v is the average velocity of the seismic wave, and t is the time that it takes for the wave to go down to the rock layer and return to the surface. If t = 0.350 +/- 0.10, and v = 2,000 +/- 10. meters per second, what is the possible error in the depth.

These animals use ultrasonic "clicks" with a frequency of about 55 kHz to navigate and find prey. Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 90 m below. How much time elapses before the dolphin hears the echoes of the clicks? (The speed of sound in seawater is approximately 1530 m/s.) What is the wavelength of 55 kHz sound in the ocean?
