An elastic conducting material is stretched into a circular loop of 9.21 cm radius. It is placed with its plane perpendicular to a uniform 0.936 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 112 cm/s. What emf is induced in volts in the loop at that instant

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
