Tom and his group were making a poster for their classroom to depict the ways to electricity and magnetism work together which of the following should the group add to their poster a a current can move a magnet be a magnet placed on a wire can stop current in a wire see magnetic fields can endurance a current D magnetic fields cause wires with no currency spin e a current can induce a magnetic field

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
