A 10-mV signal source having an internal resistance of 100 k is connected to an amplifier for which the input resistance is 10 k, the open-circuit voltage gain is 1000 V/V, and the output resistance is 1 k. The amplifier is connected in turn to a 100- load. What overall voltage gain results as measured from the source internal voltage to the load

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.
