In r4 you are given the points 2. 2 (a) write out all possible arrows which can be formed using the points p, q, r. - (hint: if your list of arrows is complete, there should be nine of them.) (b) for each of the arrows from part (a), find the vector it represents. (c) which pairs of vectors from part (b) are parallel?

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.
