What is the peak emf generated (in v) by rotating a 1000 turn, 42.0 cm diameter coil in the earth's 5.00 ✕ 10−5 t magnetic field, given the plane of the coil is originally perpendicular to the earth's field and is rotated to be parallel to the field in 12.0 ms?

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.
