Suppose that you have two machines. Machine A gives 10 horsepower, and machine B gives 20 horsepower. You will use these machines to lift an object. Suppose that Machine A takes 1 kJ of energy to lift the object, and it does so in 1 minute. Select all of the statements below that are correct (there may be one or more)? (We assume machines are using their full horsepower, and there are no losses).
A. The object will take 1/2 kJ of energy for machine B to lift.
B. The object will take 1 kJ of energy for machine B to lift.
C. The object will take 2 kJ of energy for machine B to lift.
D. The object will be lifted in V2 minute by machine B.
E. The object will be lifted in 1 minute by machine B.
F The object will be lifted in 2 minutes by machine B.
G. None of the above statements are true.

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.
