A thin rectangular coil 2 cm by 7 cm has 60 turns of copper wire. It is made to rotate with angular frequency 104 rad/s in a magnetic field of 1.7 T. (a) What is the maximum emf produced in the coil?
(b) What is the maximum power delivered to a 40 ohm resistor?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
