Suppose you're using an operant conditioning approach to teach someone how to use a bow and arrow. you begin by teaching your student how to hold a longbow. then you show him how to maintain balance while holding the bow. finally, you show him how to aim and properly release the arrow toward a target at the correct moment. this operant conditioning approach is called a. partial reinforcement. b. shaping. c. programmed learning. d. approximation. qquest

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.
