Consider an airplane patterned after the fairchild republic a-10, a twin-jet attack aircraft. the airplane has the following characteristics: wing area 47m2, aspect ratio -6.5, oswald efficiency factor 0.87, weight 103,047n, and zero-lift drag coefficient 0.032. the airplane is equipped with two jet engines with 40,298 n of static thrust each at sea level. a. calculate and plot the power-required curve at sea level. b. calculate the maximum velocity at sea level. c. calculate and plot the power-required curve at 5-km altitude. d. calculate the maximum velocity at 5-km altitude. (assume the engine thrust varies s 17m2 ar: 6.s altitude, d, i 0 32 o.00 23 directly with free-stream density.)

Geologists get to play with chemistry, physics, and history! and what a history you will meet as youwork your way through the course. starting at the beginning, the textbook provides the scientifically acceptedstart of the and promises that you'll get to explore some of the evidence for that scientific view, later inthe semester. meanwhile, which is more nearly correct of the scientifically accepted view? a) the earth formed when the big bang caused older materials to fall together, about 14 billion years ago. b) the earth formed from the falling together of older materials, about 4.6 billion years ago. c) the earth formed in the big bang, about 6000 years ago. d) the earth is eternal, having been here forever and promising to be here forever. e) the earth was assembled by gigantic space beavers, which gnawed down the primordial tree of life andpiled its branches together to form the planet.
