Air (1 atm, 5°c) with free stream velocity of 2 m/s flowing in parallel to a stationary thin 1 m x 1 m flat plate over the top and bottom surfaces. the flat plate has a uniform surface temperature of 35°c. if the friction force asserted orn the flat plate is 0.1 n, determine the rate of heat transfer from the plate.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
