Task id10401
The air is in a vertical cylinder under a piston with a mass of 20.2 kg and a cross section of 20 cm2. After the cylinder began to move vertically upward with an acceleration of 5 m/s2, the height of the air column in the cylinder decreased by 20%. Assuming the temperature is constant, find the atmospheric pressure (in kPa). g = 10 m/s2.
