Jason's circuit has a 24-Ω resistor that is connected in series to two 12-Ω resistors that are connected in parallel. Ann's circuit has three identical resistors wired in parallel. If the equivalent resistance of Jason's circuit is the same as that of Ann's circuit, determine the value of Ann's resistors.

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
