High above the stratosphere, the atmospheric temperature may reach 1091 k. however, spacecraft and astronauts do not burn up because the concentration of molecules is very low and molecular impacts on spaceships or astronauts transfer very little energy. what is the root-mean-square velocity, in m/s, of ozone molecules at that temperature

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
