Which one of the following statements concerning spherical mirrors is correct? a. only a convex mirror can produce an enlarged image.
b. both concave and convex mirrors can produce an enlarged image.
c. only a concave mirror can produce an enlarged image, provided the object distance is less than the radius of curvature.
d. only a concave mirror can produce an enlarged image, provided the object distance is greater than teh radius of hte curvature.

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.
