Always use significant figure rules. remember that these rules apply to all numbers that are measurements. a person walks along a road 3.0 miles and rests. then taking another road, he travels 5.00 miles; and switching to a dirt path, he walks 4.000 miles before arriving at his destination. how far has he traveled?

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.
