Aone-dimensional infinite well of length 175 pm contains an electron in its third excited state. we position an electron-detector probe of width 3.50 pm so that it is centered on a point of maximum probability density. (a) what is the probability of detection by the probe? (b) if we insert the probe as described 500 times, how many times should we expect the electron to materialize on the end of the probe (and thus be detected)?

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
