Asquare that has 22 cm long edges is centered on the x axis in a region where there exists a uniform electric field given by e = (1.50 kn/c) (a) what is the electric flux of this electric field through the surface of a square if the normal to the surface is in the +x direction? n m2/c (b) what is the electric flux through the same square surface if the normal to the surface makes a 65° angle with the y axis and an angle of 90 with the z axis?

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)
