- A 62.5-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 62.5-Hz sound wave? in nm What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 2.00 nm?A string is fixed at both ends. The mass of the string is 0.0010 kg and the length is 4 m. The string is under a tension of 180 N. The string is driven by a variable frequency source to produce standing waves on the string. Find the wavelengths and frequencies of the first four modes of standing waves. a. A1 = fi = Hz b. A2 = m f2 = Hz c. A3 = m f3 Hz %3D d. X4 = m fa = HzA 4.95-m, 0.736-kg wire is used to support two uniform 239-N posts of equal length (Figure 1). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 5th overtone. a. What is the frequency of the sound this wire produces? b. What is the wavelength of the sound this wire produces?
- 2 flutists are tuning their flutes with one playing a 560 Hz tone and the other playing a 548 Hz tone. A. determine the beat frequency. B. determine the resulting tone frequency everyone hears.A 90 cm-long steel string with a linear density of 1.1 g/m is under 100 N tension. It is plucked and vibrates at its fundamental frequency. a. Determine the fundamental frequency of vibration. b. What is the wavelength of the sound wave that reaches your ear in a 20° C room?A violin string of length L=31.8 cm and linear mass density µ=0.64gm/is tuned to play an A4 note at 440.0 Hz. This means that the string is in its mode of oscillation fundamental, that is, it will be on that note without placing any fingers on it. From this information, A. Calculate the tension in the string that will keep it in tune. B. If the midpoint of the string is observed to have a maximum transverse motion of 2.59 mm when in the fundamental mode, what is the maximum speed vy máx of the antinode of the string? C. If the string tension is reduced by 6.3% of the tension found in part A, what is the resulting frequency of the note produced? D. When playing the violin, different notes can be produced depending on the position of the fingers of one hand on the string. The usual technique presses the string hard against the fretboard, reducing the length of the string that can vibrate. If we consider this string initially tuned for an A4, and a finger is placed a third of the way down…

- You are at a loud rock concert. Describe how the sound goes from an external air wave to a mechanical vibration in the middle ear, then explain why it took a whole day for you to hear normally again after the concert. Include all the structures involved.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?
