Now select the light bulb as the current indicator in the circuit. Move the magnet back and forth through the coil at different rates and observe the variation of the brightness of the bulb. According to Faraday’s law of induction, the rate of change of magnetic flux through the coil is proportional to the voltage induced voltage in the coil. Why does the brightness of the bulb change when you move the magnet through the coil at different rates? Explain your answer with Faraday’s law and electrical

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
