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.)

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes. t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
