The human ear canal is about 2.8 cm long, if it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental freq. around which we would expect hearing to be most sensitive? Take the speed of sound to be 340 m/s.
Is it:
wave speed = frequency x wave...

Total cross-sectional area of a load-bearing calcified portion of 2 forearm bones is approx 2.4cm squared. During a car crash, the forearm is slammed against the dashboard. the arm comes to frest from intiial speed of 80 km/h in 5.0 ms. If arm has...
Q: When a person inhales, air moves down the bronchus (windpipe) at 15 cm/s. The average flow speed doubles through a constriction in the bronchus. Assuming incrompressible flow, determine the pressure drop in the constriction.
OK what confuses me is that I thought that if you decrease the...
