The surface of a 50-mm-diameter, thin-walled tube is maintained at 100 c. in one case air is in cross flow over the tube with a temperature of 25 c and a velocity of 30 m/s. in another case air is in fully developed flow through the tube with a temperature of 25 c and a mean velocity of 30 m/s. compare the heat flux from the tube to the air for the two cases.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
