Calculate the average kinetic energy and RMS velocity of a xenon atom at 166.126 K, which is just 1.075 degrees above the boiling point of xenon at 1 atmosphere pressure. The atomic mass of xenon is 131.293 amu. Because the kinetic energy of a single atom is so tiny, express the KE in units of 10−23 10-23 J.

Consider the diatomic oxygen molecule, O_2, which is rotating in the xy plane about the z axis passing through its center, perpendicular to its length. At room temperature, the "average" separation between the two oxygen atoms is 1.21 times 10^-10 m (the atoms are treated as point masses, each with 2.66 times 10^-26 kg.)

A 0.45 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 24.0 N/m. Let x be the displacement, where x = o is the equilibrium position and x > 0 when the spring is stretched. The object is pushed, and the spring compressed, until хі =-4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the object's maximum speed (in m/s) after it is...
