I need the answer as soon as possible

A 480-V, 60-Hz, 50-hp, three-phase induction motor is supplying by 60 A at 0.85 PF lagging. The stator copper losses are 2 kW. and the rotor copper losses are 700 W. The friction and windage losses are 600 W, the core losses are 1800 W, and the stray losses are negligible. Find the following quantitiest (a) The air-gap power (b) The power converted (c) The output power (d) The efficiency of the motor A 460-V. 25-hp. 60 Hz, four-pole. V-connected induction motor has the following impedances in ohms per phase referred to the stator circuit: RI=0.641 ohm X1 = 1.106 ohm R2 -0.332 ohm X2 -0.464 ohm and Xm - 26.3 ohm
