The motion of space shuttles is caused differently than that of most modes of transportation. As the fuel is burned, the hot gasses produced rush out of the bottom of the craft. This causes the space shuttle to launch into the air. Describe how hot gasses rushing out of the bottom of a space shuttle cause it to launch.

In your response, be sure to include:

something about the forces acting on the space shuttle causing it to launch.
how Newton’s third law allows the space shuttle to launch.
why there is a delay between when the fuel starts to burn and when the space shuttle launches.

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.
