Topic: Waves and Sound My textbook pops up this equation out of nowhere: V=sqrt(TL/M). Explain why the square root of tension and the length of the string is proportional to V

A car is moving to the right blasting the "Cantina Band" song from Star Wars IV A New Hope. The car is approaching a wall at 30 m/s. If we consider (for simplicity) that the frequency is 300 Hz and that sound travels at 340 m/s in air, what is the frequency of the sound the driver hears reflected off the wall?

Topic: Doppler Effect Two cars from different lanes approach each other. Car A moves at 80.0km/h and car B moves at 76.0 km/h. If Car A honked with a frequency of620.0 Hz then what is the frequency of sound heard by the driver of carB?

Two sound waves, which are initially in phase, travel two different distances, x1and x2toan observer/listener. Write a sentence or two about how the difference in distance, Δx,relates to the wavelength of the sound if the listenerhears maximum constructiveinterference at this location.

QUESTION 4 Lab Exercise 6: Calculating the Speed of Sound Use the equation: λ = 4(L + 0.3d) , to solve for the wavelength of sound.  This is the info I can give you: 3 cm diameter of plastic pvc pipe 17 cm of water 1 meter pvc tube  100 cm - 16.9 cm = 83.1 cm from the top of the tube to the top of the water gave me the loudest sound What is the calculated wavelength?

Standing Wave Lab Here is the link for the simulation: http://physics.bu.edu/~duffy/HTML5/wave.html  It says I got it partially right but I'm not sure which is wrong. Please help me.

(Question 22) Answer step to step the following question: Two speakers on the Ox axis emit sound waves from the same direction along the axis. Speaker 2 is 2.0 m behind speaker 1. The two speakers are connected to the same signal generator, which oscillates the 340 Hz, but the wire connecting it to speaker 1 goes through a box containing a electronic device that delays the signal by 1.47 ms. Along the Ox axis. To along the Ox axis, the interference is totally constructive, totally destructive or something in between? (Consider v= 340 m/s) Justify your asnwer.

(Q222) Answer the following question step by step: Two speakers emit 500 Hz sound waves with amplitudes of 0.10 mm. Speaker 2 is 1.0 m behind speaker 1, and the phase difference between them is 90◦. What is the amplitude of the sound wave heard at a point 2.0 m in front of speaker 1? Justify your answer.

Good day Maam/Sir, I hope you will help us in this problem. Thank you! Topic: Sound and Hearing Problem: Two cars red and gray are moving towards each other with a speed of 1832 cm/s. If the red car is playing a music with frequency emitted is 12, 800 Hz, then what is the apparent frequency of the music heard by the passenger sitting in the gray car. (The velocity of sound in air is 273 m/s)

Answer the questions using the simulation above Set the frequency of wave 1 to 428 Hz and the frequency of wave 2 to 436 Hz. (a) Waves 1 and 2 are precisely in phase with one another at t = 0. If you look at the sum of the two waves, you can see that the amplitude of their sum drops to zero at one particular time between 50 and 100 ms (there are lots of places where the sum is zero, but only one place where the envelope enclosing the fast oscillations is zero, and that's the point we're interested in). Precisely when is the time, between 50 and 100 ms, when the amplitude of the sum is zero?(b) How many periods does this time correspond to for wave 1? You can get a pretty accurate idea of this by counting peaks on the wave 1 graph, but you should calculate it accurately.(c) How many periods does this time correspond to for wave 2? Note the difference between your answers for parts (b) and (c). It should be exactly half a period, which is why the waves experience completely destructive…
