An object starts from rest at point F and speeds up continuously as it moves around an oval. a. Choose a point about 1/8 th of the way around the oval from point F, and label it point G. Draw a vector to represent the velocity of the object at point G. b. Determine the change in velocity vector  between points F and G.

The plum pudding model of the atom states that ?

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.
