Abeam of yellow monochromatic light passes from liquid water (n=1.333) into ice (n=1.309). in the liquid water, the beam makes an angle of 40.0 with the normal. when the beam is traveling in the ice, what angle does it form with the normal?
40.7
39.3
41.2
68.5

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
