For a given wing–body combination, the aerodynamic center lies 0.03 chord length ahead of the center of gravity. The moment coefficient about the center of gravity is 0.0050, and the lift coefficient is 0.50. Calculate the moment coefficient about the aerodynamic center.

-0.01

Explanation:

given:

C_l=0.5

C_gravity=0.0050

C_chord= 0.50

solution:

C_moment=C_chord+C_l(h-h_ac)

                 =0.0050-0.5(0.03)

                 = -0.01

it would be kevlar ^^

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
