Carl and abby are discussing what they have learned in class about electricity and magnetism. carl tells abby that an electric current running along a wire can be used to produce a magnetic force. abby, on the other hand, tells carl that moving electrons through a magnetic field can produce an electric current.

which of the students is/are correct?

both carl and abby are correct.

only carl is correct.

only abby is correct.

neither student is correct.

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.
