You have a stopped pipe of adjustable length close to a taut 62.0 cm, 7.25 g wire under a tension of 4510 N. You want to adjust the length of the pipe so that, when it produces sound at its fundamental frequency, this sound causes the wire to vibrate in its second overtone with very large amplitude. The speed of sound in air is 344 m/s. Part A How long should the pipe be? Express your answer with the appropriate units. L = 6.8 Submit μA cm 2 ? Previous Answers Request Answer

A certain organ pipe, open at both ends, produces a fundamental frequency of 275 Hz in air. Part A If the pipe is filled with helium at the same temperature, what fundamental frequency fHe will it produce? Take the molar mass of air to be 28.8 g/mol and the molar mass of helium to be 4.00 g/mol. Express your answer in hertz. ► View Available Hint(s) fHe = 806 Hz Submit Previous Answers Correct Correct answer is shown. Your answer 805.9 Hz was either rounded differently or used a different number of significant figures than required for this part. Because helium is less dense than air and has a lower molar mass, sound waves propagate faster in helium than in air. Thus, the frequencies produced in the pipe when it is filled with helium are higher than those produced in the same pipe filled with air. Part B Now consider a pipe that is stopped (i.e., closed at one end) but still has a fundamental frequency of 275 Hz in air. How does your answer to Part A, ƒHe, change? ► View Available…
V Hint The heat transfer behavior of a sample of opaque fluid is being investigated. A series of ultrasound transducers send sound waves through various portions of the sample, and the time it takes for the sound wave to travel through the sample is measured at each location. From this information, researchers are able to reconstruct a rough temperature field of the sample. The false-color image of the sample is divided into three regions based on the measured sound wave transmission times. Region A has a sound wave transmission time of 35.4 ms, region B has a sound wave transmission time of 33.2 ms, and region C has a sound wave transmission time of 33.5 ms. Assuming a uniform sample thickness, rank regions A, B, and C based on their temperatures, from highest to lowest.

How is white light different from the rest of the electromagnetic spectrum? White light is capable of altering its wavelength. O White light can travel through empty space and matter. White light is invisible to the human eye. O White light has a spectrum of visible colors.
The figure shows the circular wave fronts emitted by two sources, the wavelength for both idential waves is 1.4 m. What is the path-length difference at point Q, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
