Aisha, saul, and lorenzo are playing a tug-of-war. saul and lorenzo are pulling at 90 ^\circ90 ∘ 90, degree to each other, while aisha is pulling with 20\text{ n}20 n20, space, n on her rope at an angle (90 + \theta)^\circ(90+θ) ∘ (, 90, plus, theta, ), degree from lorenzo. given that \theta = \arctan(1.33)θ=arctan(1.33), what are the magnitudes of force with which saul and lorenzo must pull in order to keep this system in equilibrium?

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)
