What causes seasons on Earth? A.
The tilt of the Earth's axis, as it revolves around the Sun, causes unequal heating on Earth's surface.

B.
Based on Earth's orbit, the Earth is closer to the Sun in the summer and further away in the winter.

C.
Earth's tilted axis causes the Earth to be closer to the Sun at times and further away at other times.

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.
