Which of newton's laws describes that a large massive body requires a large force to change speed quickly?

Fill in the blank. the number of each type of element in the compound (other than 1) is represented by a small number to the right of the element symbol.

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.
