Compared to the mass and charge of a proton,
an antiproton has
(1) the same mass and the same charge
(2) greater mass and the same charge
(3) the same mass and the opposite charge
(4) greater mass and the opposite charge
note that question 35 has only three
choices.

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.
