MARKING BRAINLIEST: A 75.0 kg person rides up and down in an elevator that starts from rest, accelerates from rest to 2.0m/s in 2.0s, continues at a constant velocity of 2.0m/s for 2.0s, and then comes to a stop from 2.0m/s in 2.0s. Calculate what the scale would read in each of the following situations. Show all work including free-body diagrams. Round off g to 10 m/s2.

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)

Anybody wanna ? (picture included? )

A40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the. volume of the ammonia if it’s pressure is changed to 8.4 kpa while its temperature remains constant.
