Larry and balky set up an experiment to analyze the motion of a marble as it rolled down an incline. they started the marble at the top of the ramp and set up photogates to collect data as the marble rolled down the ramp. which graph format would allow larry and balky to calculate instantaneous velocity using slope? a) velocity on the y-axis, time on the x-axis b) distance on the y-axis, time on the x-axis c) time on the y-axis, distance on the x-axis d) velocity on the y-axis, distance on the x-axis

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.
