Suppose that you are standing by theside of a road in the Sahara desert where the temperature has reached ahot 56 °C (130 °F). A truck, traveling at a constant speed, passes by. After4.00 s have elapsed, you use the ultrasonic ruler discussed in Example 4to measure the distance to the truck. A sound pulse leaves the ultrasonicruler and returns 0.120 s later. Assume that the average molecular massof air is 28.9 u, air is an ideal diatomic gas (y = }), and the truck movesa negligible distance in the time it takes for the sound pulse to reach it.Determine how fast the truck is moving.

Given: The temperature is T=56°C. The elapsed time is t=4 s. The time taken by sound pulse to…

An osprey's call is a distinct whistle at 2200 Hz. An osprey calls while diving at you to drive you away from its nest. You hear the call at 2300 Hz. Part A How fast is the osprey approaching? Express your answer with the appropriate units. v= μA Value Units ?
5. A quantum object travels directly toward you at a constant rate while producing a sound with a singular frequency of 440 Hz. While you stand still, the object passes through you and continues Moving (you are uninjured). You measure an overall shift in the frequency you hear to be 25.0 Hz. Assume is it 20.0 °C during this shift. a) What is the speed of this particle? b) After is passes through you, you notice that your wallet is missing and see it attached to this particle. You begin accelerating toward the particle at a constant rate of 1.50 m/s² via ion propelled roller shoes. At what time do you perceive a frequency of 435 Hz? c) You stop accelerating when you perceive a frequency of 435 Hz and continue to travel at a constant rate at which time the particle then instantaneously reverses it path to return your wallet, traveling back toward you at its same constant rate which it initially had. What frequency do you then perceive at it travels toward you?
Pr5. Two identical loudspeakers are located at points (-10,0,0) and (0,0, 10) of our coor- dinate system, where the numbers in the brac- kets correspond to the (r, y, z) coordinates of the points, expressed in meters. The loudspeakers are driven by the same oscillator with a frequ- ency of 170 Hz. The speed of sound in air can be considered 340 m/s. a) Give the coordinates of those points loca- ted on the positive r axis where the sound waves coming from the two loudspeakers interfere con- structively. b) A receiver is started to move slowly from the origin (0,0,0) along a path lying in the r-y plane so that it receives constant sound intensity throughout its slow motion. What is the shape of the path the receiver should take?
A train whistle is heard at 250 Hz as the train approaches town. The train cuts its speed in half as it nears the station, and the sound of the whistle is then 240 Hz.

Oil explorers often set off explosives to make loud sounds, then listen for the echoes from underground oil deposits. Geologists suspect that there is oil under 520-m-deep Lake Physics. It's known that Lake Physics rests on top of solid granite. The speed of sound in water is 1480 m/s and the speed of sound in granite is 6000 m/s. a. If an explosion is created at the surface of the lake, what time after the explosion do the explorers expect to hear an echo from the bottom of the lake in seconds? t=0.703s b. In addition to the expected echo from the bottom of the lake, explorers also detect a faint echo 0.960 s after exploding the dynamite at the lake surface. If it's really oil, how deep will they have to drill through the granite to reach it in meters?
Simon drives to a restaurant where he notices that the door to the kitchen swings both in and out to allow serving staff to rapidly get to and from the kitchen. After a member of staff passes through the door it swings back and forth three times before coming to rest. The door is released a distance of 0.70 m from the frame and swings with a frequency of 0.40 Hz. b Draw a graph to show how the displacement varies with time until the door comes to rest. Include values where possible.
