Astudent is swimming south applying a force of 256 n. the water exerts a westward force of 104 n. if the student has a mass of 95.3 kg, what is the acceleration of the student? hint: the weight of the student is balanced with the water buoyant force, therefore those are the only forces affecting the resultant force.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
