An evacuated 150-l tank is connected to a line flowing air at room temperature, 25o c, and 8 mpa pressure. the valve is now opened, allowing air to flow into the tank until the pressure reaches 6 mpa, at which time the valve is closed. the filling process occurs rapidly and is essentially adiabatic. the tank is then allowed to sit for a long time with the valve closed, and eventually returns to room temperature. what is the final pressure inside the tank, in mpa? what is the mass of the air that entered the tank, in kg?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
