Q. A vertical cylindrical cylinder, closed at the bottom end, contains 0.010 moles of gas. It is fitted at the top with a piston, which can move freely. The mass of the piston is 14.0 kg and the initial height of the piston above the bottom of the cylinder is 25.00 cm. What is the temperature of the gas?
Q. Four particles with masses 9kg, 4kg, 9kg, and 3kg are associated by rigid rods of negligible mass as shown. Assume the system rotates in the yz plane about the x axis with an angular speed of 9 rad/s. Find out the moment of inertia of the system about the x axis.
