The coil in an ac generator consists of 21 turns of wire, each of area a = 0.12 m2, and the total resistance of the wire is 24 ohms. the coil rotates in a 0.5 tesla magnetic field at a constant frequency of 135 hz. find the maximum induced emf in the coil (in volts).

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
