An airplane traveling at 0.425 km/s in a region where the earth’s magnetic field is and the velocity of the plane is vertical to the magnetic field. a)What is the potential difference E. M.F. induced between the ends of the airplane’s wings that are 2,800 cm apart? g

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
