Consider a piston engine airplane with a parasite drag coefficient of 0.02 when its landing gear is retracted, and 0.025 when it is deployed. assume that the other drag polar parameter k does not change. the airplane is deigned to cruise for minimum power requirement with its landing gear retracted at certain altitude. determine the % increase or decrease in the minimum power required if the airplane executes the same flight with its landing gear deployed (as may happen if its retraction mechanism fails)

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
