I need the answer as soon as possible

Rotor Sample 34.8. A 1100-V, 50-H: delta-connected induction motor has a star connected slip-ring w a phase transformation ratio of 3.8. The rotor resistance and standstill leakage reac- 0.012 ohm and 0.25 ohm per phase respectively. Neglecting stator impedance and the rotor current at start with slip-rings shorted ? the rotor power factor at start with slip-rings shorted ong current determine the rotor power factor at 4% slip with slip-rings shorted the rotor current at 4% slip with slip-rings shorted the external rotor resistance per phase required to obtain a starting current of 100 A in the stator supply lines.
