Use evidence and scientific reasoning to explain why the reading on the balance increased as Magnet 2 was lowered towards Magnet 1. Remember that Magnet 1's North pole was facing upwards while resting on the balance. In your response, be sure to describe the magnetic field interactions and the orientation of the magnetic poles for each magnet.

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
