When you drink cold water, your body must expend metabolic energyin order to maintain normal body temperature (37°c) by warmingup the water in your stomach. could drinking ice water, then, substitute for exercise as a way to "burn calories? " suppose youexpend 520 kilocalories during a brisk hour-long walk. how manyliters of ice water (0°c) would you have to drink in order touse up 520 kilocalories of metabolic energy? for comparison, thestomach can hold about 1 liter.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
