<span>In this case, the nurse would believe that the patient was experiencing Tension pneumothorax. Tension pneumothorax is the build up of air over time in a pleura space. It is generally caused by a laceration in the lung which lets air pass into the pleura space but then get stuck there. It presents a pressure which makes ventilation difficult, it cause the same effects as a one way valve.</span>
Therefore, in Doppler Effect only the frequency and wavelength are changes and the wave speed does not change
I believe it’s A but I’m not too sure
Reason; Warm air rises, and when it rises it becomes cooler. ... If the pressure of the surrounding air is reduced, then the rising air parcel will expand. The molecules of air are doing work as they expand. This will affect the parcel's temperature (which is the average kinetic energy of the molecules in the air parcel).
