I need help, It's all about Electric Motors and Faraday's Law. Show your solution clearly, Thank you so much.

Electric Motors: 1. A generator has an armature with 500 loops, which cut a flux of 8.00 mWb during each rotation. Compute the back emf it develops when run as a motor at 1500 rpm. 2. The active length of each armature conductor of a motor is 30 cm, and the conductors are in a field of 0.40 Wb/m . A current of 15 A flows in each conductor. Determine the force acting on each conductor. Faraday's Law: 3, A circular conducting coil with radius 3.40 cm is placed in a uniform mag- netic field of 0.880 T with the plane of the coil perpendicular to the magnetic field. The coil is rotated 1809 about the axis in 0.222 s. (a) What is the Axis average induced emf in the coil during this rotation? (b) If the coil is made of copper with a diameter of 0.900 mm, what is the average current that flows through the coil during the rotation
