Question in the attachments Sound travels at different speeds in air, depending on the temperature. Suppose the speed of sound at a certain time is 382.4 m/s. A device producing sound is increasing in frequency at a constant rate \(df/dt = 69.1 \, \text{Hz/s}\). Find \(d\lambda/dt\), the rate at which the wavelength is changing in m/s at the moment the frequency is 201 Hz. The sign should be positive if it is increasing, and negative if it is decreasing.

The wavelength of the sound is given by, λ=vf Here, v is the speed of the sound. The rate at which…

. During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.
