A student is modeling an image that will be produced by a double concave lens. the students make a prediction that the “x” should be placed in between the object and the lens to represent the image created by the double concave lens.

construct an argument with a claim that agrees or disagrees with the students prediction. support your claim with evidence from the model and use your knowledge of concave lenses as reasoning to pink your claim with your evidence.

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.
