Steam contained in a piston–cylinder assembly is compressed from an initial volume of 50 m3 to 30 m3. if exergy transfer accompanying work is 500 kj and the dead state pressure is 1 bar, determine the energy transfer by work, in kj, for the process.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
