0out of 15 points if the continuous time signal y(t) = 2 cos (-2*π*56*t) is sampled at a frequency of 52 hz, and the corresponding discrete-time signal is then reconstructed at the same sampling frequency, what is the frequency of the resulting continuous time signal (in hz)? include the sign (- or +) of your answer, as determined directly from the frequency calculations. in other words, do not simplify using cos(-x) = cos(x)

How have the competing explanations' experiments on atoms affected the development of the atomic model?

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.
