Two parallel rails with negligible resistance are 10.0cm apart and are connected by a 5.00Ω resistor. The circuit also contains two metal rods having resistance of 10.0Ω and 15.0Ω sliding along the rails. The rods are pulled away from the resistor at a constant speeds 8.00m/s and 4.00m/s respectively. A uniform magnetic field 0.010T is applied perpendicular to the plane of the rails. Determine the current in the 5.00Ω resistor. Calculate the total power needed to move the two rods at constant speed. (Express your answer in
W). (Note: This is the same as the power delivered by the induced emf's).

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
