2. An airplane weighing 73.6 kN has elliptic wings 15.23 m in span with no geometric twist and a planform area of 19.8 m2 . For a speed of 90 m/s in steady, level flight at sea level ( = 1.2256 kg/m3 ) calculate the value of the circulation in the plane of symmetry (o), the downwash velocity, w, the induced drag, D, i, the geometric angle of attack, , and the effective angle of attack, eff. Assume that L=0 = -1.2°.

Explain vector addition, triangle method and parallelogram method

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
