Write a short story (about three paragraphs) in which you use the principles of light ray reflection. your story should include the words "incident ray," "reflected ray," "angle of incident," and "angle of reflection." your story could be about solving a mystery, spying by using light ray reflection, or anything else you like related to light ray reflection.

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.
