Adisc magnet is used to hold a piece of paper (0.1 mm thick) to the door of a refrigerator. the magnet is 6 cm in diameter and 0.75 cm thick. its mass is 500 grams. assuming that the coefficient of friction between the paper and the refrigerator is 0.3, what is the minimum remanent magnetism (in gauss) that the magnet must have in order to keep the magnet and paper from falling?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
