The average kinetic energy of translational motion of a molecule, in equilibrium, is (3/2)kBT. What is the average of the velocity squared in pure oxygen (O2) at standard pressure (1 bar) and concentration 0.001 mole/L? Give answer in (m/sec)2 . (To determine the temperature, please use the equation of state for the ideal gas.)

Review Constants part. Consider the system of two blocks shown in (Figure 1). The blocks are released from rest. While the two blocks are moving, the tension in the light rope that connects them is 35.0 N. Part 6 If the work-energy theorem is applied to the two blocks considered together as a composite system, use the theorem to find the network done on the system during the 0.900 m downward displacement of the 6.00 kg block. Express your answer...
