|Question 4A certain organ pipe, open at both ends, produces a fundamentalfrequency of 293 Hz in air at a given temperature. At thattemperaturer, the speed of sound in air is 346 m/sPart A - speed of sound in heliumWhat is the speed of sound in helium at the same temperature as air?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 m/s.Part BSo, if the pipe is filled with helium at the same temperature, what fundamental frequency fle will it produce?Express your answer in hertz.Part C-A symphonie in heliumNow consider another pipe, one end open, one end closed, but of different length, so that it still has the same fundamental frequency of 293 Hz in air.

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…

A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?
a. Students in a physics lab are asked to find the length of an air column in a tube closed at one end that has a fundamental frequency of 230 Hz. They hold the tube vertically and fill it with water to the top, then lower the water while a 230 Hz tuning fork is rung and listen for the first resonance. What is the air temperature (in °C) if the resonance occurs for a length of 0.380 m? b. At what length (in m) will they observe the second resonance (first overtone)?
please quickly thanks ! You have two mono-frequency sound sources. If you set one frequency as 600Hz, and sweep another frequency from 597Hz to 603Hz, what will happen to the sound intensity you measure?
