Two moles of nitrogen are initially at 10 bar and 600 K in piston/cylinder device. The system is expanded adiabatically against a constant external pressure of 1 bar until it reaches mechanical equilibrium. Calculate the final temperature, the heat transferred, and the work of the system. You may assume ideal gas behavior for nitrogen. Use a temperature-dependent heat capacity for nitrogen.
Two forces FA and FB are applied to an object whose mass is 5.43 kg. The larger force is FA. When both forces point due east, the object's acceleration has the magnitude of 1.40 m/s2. Though, as FA points due east and FB points due west, the accelera..
