Three small spheres A, B, and C, each of mass m, are connected to a small ring D of negligible mass by means of three inextensible, inelastic cords of length l. The spheres can slide freely on a frictionless horizontal surface and are rotating initially at a speed v0 about ring D, which is at rest. Suddenly the cord CD breaks. After the other two cords have again become taut, determine
(a) the speed of ring D,
(b) the relative speed at which spheres A and B rotate about D,
(c) the fraction of the original energy of spheres A and B that is dissipated when cords AD and BD again became taut.

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.
