A1.80m long uniform bar that weighs 608 n is suspended in a horizontal position by two vertical wires that are attached to the ceiling. one wire is aluminum and the other is copper. the aluminum wire is attached to the left-hand end of the bar, and the copper wire is attached 0.400m to the left of the right-hand end. each wire has length 0.600m and a circular cross section with radius 0.250mm.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
