A heavy steel cable attached to a motor is lifting a girder. The girder is speeding up. Part A.) Draw a free-body diagram for the steel cable

Part B.) Draw a free-body diagram for the girder.

Please help, I am pretty confused. Thank you!

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
