Consider atmospheric air at 20°c and a velocity of 30 m/s flowing over both surfaces of a 1-m-long flat plate that is maintained at 130°c. determine the rate of heat transfer per unit width from the plate for values of the critical reynolds number corresponding to 105, 5 × 105, and 106

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

How do you tell if someone actually cares about you? and just say they do?
