3. The spring in a marble launcher is compressed 0.080 m by a marble of mass 0.0051 kg and is locked in. The launcher makes an angle of 62° with the horizontal. The spring is
released and the marble exits the launcher. How much did the GPE of the marble change
as it moved from the compressed to the released position of the spring (Ax = 0.080 m)
along the barrel of the launcher?

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.
