Find the equivalent impedance Zeq seen by the source when Vs = 2 cos (3t) v, C = 2 F, R = 1 Ω and L = 0.1 H. (Give angles in degrees and round final answers to two decimal places.) Calculate the voltage across the inductor. (Give angles in degrees and round final answers to two decimal places.)

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
