A sound wave arriving at your ear is transferred to the fluid in the cochlea. If the intensity in the fluid is 0.410 times that in air and the frequency is the same as for the wave in air, what will be the ratio of the pressure amplitude of the wave in air to that in the fluid? Approximate the fluid as having the same values of density and speed of sound as water. Speed of sound in dry air (20.0°C, 1.00 atm) is 343 m/s, density of dry air (at STP) is 1.29 kg/m3, density of water is 1000 kg/m3, and speed of sound in water is 1493 m/s.

A tube 0.8 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.33 m long and has a mass of 9.6 g. It is fixed at both ends and oscillates in its fundamental model. By resonance, the vibrating string causes the air column in the tube to oscillate at the column's fundamental frequency. What is the tension in the wire. Hint: Determine the wavelength of the air column using the relationships in 9.13.2 on page 31 of your notes. Determine the frequency using a speed of sound of 343 m/s. The frequency of the string will be the same as the frequency of the air column. Determine the string wavelength based upon the length to wavelength relationships on page 30. Determine the required string wave speed based upon the string wavelength and frequency. Determine the string tension required to achieve string wave speed.

You are part of a scientific expedition that landed in the planet Martech. The planet has an atmosphere of an unknown gas. In your preparation for the mission you prepared the following table, a resonance tube and a sonic device that can produce three frequencies: 261HZ, 330HZ and 512HZ. Temperature (°c Speed (m/sec) Substance CO2 258 CO2 20 267 Air 331.5 Air 20 344 Water Vapor Helium Hydrogen 20 395 20 927 1,270 Argon 20 300 Delakium 20 2950 You measured the temperature of the gas in the atmosphere and recorded 20 degree Celsius. Remembering the valuable learning experience you had in your class Science and Technology in the Arts, you need to determine the gas of the atmosphere on the planet Martech. When rushing to implement the experiment, you used the sonic device to produce the three frequencies above the resonance tube, but recorded only the length of the resonance tube that produced the first maximum intensity for each one of them without recording the frequency of the sonic…
