A cylinder is fitted with a freely- sliding piston containing an ideal gas of mass 13g and volume 1.0 x 104 cm?. The temperature of the gas is
25°C and is initially at atmospheric pressure 1.0 x 105 Pa.
i) If the gas was heated to 400°C, calculate its new volume.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
