Abattery contains two metals that have different tendencies to attract electrons. if one is lithium with an electron affinity of ? 3.05, and the other is zinc with an electron affinity of ? 0.76, describe how the electrons will flow. then, describe how you could make this an even stronger battery

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.
