Aparticle (charge 7.5 μc) is released from rest at a point on the x axis, x = 10 cm. it begins to move due to the presence of a 2.0-μc charge which remains fixed at the origin. what is the kinetic energy of the particle at the instant it passes the point x = 1.0 m? (a) 3.0 j(b) 1.8 j(c) 2.4 j(d) 1.2 j(e) 1.4 j

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.
