Which statement best describes how the magnitude and direction of the bowling ball's velocity changed with each tap of the baton? the direction of velocity changed due to the force applied by the baton, but the magnitude of the velocity did not significantly change. the magnitude of the ball's velocity decreased due to the force applied by the baton, but the direction of the velocity did not change. the magnitude of the ball's velocity increased due to the force applied by the baton, but the direction of the velocity did not change. no change in either the magnitude or direction of the ball's velocity occurred due to the force applied by the baton

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. (3.32 mw; 9.69 mw; 4.25 mw; 5.82 mw)
