Steam at 4 mpa and 400°c enters a nozzle steadily with a velocity of 60 m/s, and it leaves at 2 mpa and 300°c. the inlet area of the nozzle is 50 cm2 , and heat is being lost at a rate of 75 kj/s. determine (a) the mass flow rate of the steam, (b) the exit velocity of the steam, and (c) the exit area of the nozzle. (page 217).

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?
