Consider an acoustic wave encountering a fat/liver interface at normal incidence. what fraction of acoustic intensity (not pressure) is reflected back from the fat/liver interface at normal incidence? (you can take the acoustic impedances of fat and liver to be 1.35 x 10^6 kg m^-2 s^-1 and 1.66 x10^6 kg m^-2 s^-1 , respectively.) does it matter from which direction the incident energy arrives? why or why not?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
