A dragonfly can move 12 times as fast as a cockroach. If the dragonfly flies 33 miles per hour faster than the cockroach can crawl, write an equation that best describes the speed of the dragonfl...
If one wanted to help insulate their house, by replacing their windows made of the same material, would it be better to have, smaller windows (say let A = ½ original) or thicker glass (say twice...
If a tank has 2.50 g of N2 (nitrogen atom has 14 nucleons) and a volume of 1950 cm3 and it is held at 142 0 C, what is the pressure?
Rivets can be cooled before they are put in place, thus when they reach equilibrium temperature they are more firmly fixed in place. If the volume expansion of iron is 35.0 X 10-6 K-1 what difference of...
