During a 4th of July celebration, an M80 firework explodes on the ground, producing a bright flash and a loud bang. The air temperature of the night air is T30.50°C.Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.10 seconds. The second observer notes the differenceas 2.20 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance Ax (in m) between the two observers?Line of SightObs,Line of SightObs1Obs,Ax2AxObs2

Deep underwater, a sub moves through still water at a speed of 23 m/s. The sub sends out a 910 Hz sonar wave towards an underwater mountain. The wave reflects off the mountain and the sub detects the reflected wave. (The speed of sound in water is 1482 m/s.) Hint: this problem requires two parts. The sub is the source for the initial wave. The frequency does not change when the wave reflects from the mountain. For the reflected wave, the sub is the detector. What frequency does the sub detect for the reflected wave?
A sound wave is modeled as ΔP=2.27 Pasin(50.46 m−1⋅x−17156 s−1⋅t)ΔP=2.27 Pasin(50.46 m-1⋅x-17156 s-1⋅t). What is the maximum change in pressure, the wavelength, the frequency, and the speed of the sound wave? ΔPmax=ΔPmax= Correct Pa λ=λ= Correct m f=f= Incorrect Hz v=v= Incorrect m/s
Four sound waves are to be sent through the same tube of air, in the same direction: s1(x,t)=(2.20nm)cos(2⁢π⁢x-700⁢ ⁢ π⁢t⁢) s2(x,t)=(2.20nm)cos(2⁢π⁢x-700⁢ ⁢ π⁢t⁢+0.6π) s3(x,t)=(2.20nm)cos(2⁢π⁢x-700⁢ ⁢ π⁢t+π⁢) s4(x,t)=(2.20nm)cos(2⁢π⁢x-700⁢ ⁢ π⁢t⁢+1.6π) What is the amplitude of the resultant wave?
When two waves come toward one another, they will interfere. Under which circumstances will the maximum constructive interference occur? a A crest of 10 m interfering with a crest of 10 m b A crest of 5 m interfering with a crest of 2 m c A crest of 7 m interfering with a trough of 5 m d A crest of 10 m interfering with a trough of 10 m
Two sinusoidal waves travelling in the same direction with the same amplitude, wavelength, and speed, interfere with each other to give the resultant wave: y_res (x,t) = 2 cm sin(4πx-60πt+π/3). The amplitude of the individual waves generating this wave is: 2/√3 cm 2 cm 8 cm 4/√3 cm 4 cm
You're using an ultrasonic sensor in the deep depths of the ocean to identify shipwrecks. However, you first need to calibrate your sensor for these conditions, as the speed of sound is unknown in the cold, high pressure conditions you are working in. You set up an experiment in a lab where you recreate the environmental conditions of the deep ocean and place an object 30 m from an ultrasonic sensor. The total travel time of the ultrasonic wave is 33 ms (milliseconds). What is the speed of sound in these conditions?
1. In still air, with a speed of sound, v= 343.0m/s, a source of sound A is moving directly toward a reflecting surface B. Reflecting surface B is moving directly away from source A. The speed of A is v, =162 km / h and the speed of B is VR = 86.4 km / h. Sound source A emits waves of frequency f, =1200.0 Hz in the frame of A. а. What is the frequency heard by a detector mounted on and moving with reflecting surface B, Bd b. What is the frequency of the reflected wave as heard by a detector mounted on and moving with sound source A, JAd ?
A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.6 s for the boat to travel from its highest point to its lowest, a total distance of 0.53 m. The fisherman sees that the wave crests are spaced 4.8 m apart. How fast are the waves traveling? (Give your answer in m/s.)
Two waves, of the same wavelength are travelling in opposite directions. One wave has an amplitude of 10 cm, while the other wave has an amplitude of 5 cm. What is the magnitude of the amplitude of the resulting wave when the waves are constructively interfering? Question 5 options: 5 cm 20 cm 15 cm 10 cm
Two train whistles have identical frequencies of 1.58 102 Hz. When one train is at rest in the station and the other is moving nearby, a commuter standing on the station platform hears beats with a frequency of 4.00 beats/s when the whistles operate together. What are the two possible speeds that the moving train can have? moving away from the station ?m/s moving towards the station ?m/s
While attending a large fireworks event with music, you decide to stay 1 kilometer away because of the crowds. However you have a good view, and you can still hear the booms, as well as the music. Given a speed of sound on a warm moist summer night of 340 m/s, select those that apply. The music is out of phase with the fireworks and occurs about 3 seconds late. The booms are so loud they occur at the same time as the flash of fireworks explosion. The booms follow the flashes you see by about 3 seconds. The music has the wrong pitch with its frequency changed by the time it takes to reach you. The music is out of phase with the fireworks and occurs about 6 seconds early CAN BE MORE THAN ONE ANSWER
