The convection heat transfer coefficient for a clothed person standing in moving air is expressed as h = 14.8v0.69 for 0.15 < v < 1.5 m/s, where v is the air velocity. for a person with a body surface area of 1.7 m2 and an average surface temperature of 29°c, determine the rate of heat loss from the person in windy air at 10°c by convection for air velocity of 0.9 m/s. (round the final answer to one decimal place.)

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
