In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds. What was the acceleration of the cart with Low fan speed? cm/s^2

What was the acceleration of the cart with Medium fan speed? cm/s^2

What was the acceleration of the cart with High fan speed? cm/s^2

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.
