A coil with a wire is wrapped 40.0 turns around a 0.50m2 hollow tube. A magnetic field is applied perpendicularly to the plane of the coil. The field changes uniformly from 0.00 T to 0.95 T in 2.0 s. If the resistance in the coil is 3.0Ω, what is the magnitude of the induced current?

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.
