The maximum torque on a set of 20 square loops with edge lengths of 6 cm in a 4.0 t magnetic field is: a) 0.288 n-m. b) 4.8 n-m. c) 0.014 n-m. d) not enough information is stated. the torque depends on the amount of current in the loop.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
