Awheel is rotating about an axis that is in the
z-direction. the angular velocity ωz is -6.00 rad/s at t = 0, increases linearly with time, and is +4.00 rad/s at t = 16.0 s . we have taken counterclockwise rotation to be positive.
part a
is the angular acceleration during this time interval positive or negative?
part b
how long is the time interval during which the speed of the wheel is increasing?
express your answer with the appropriate units.
part c
how long is the time interval during which the speed of the wheel is decreasing?
express your answer with the appropriate units.
part d
what is the angular displacement of the wheel from t = 0 s to t = 16.0 s

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.
