a) 24mg(12p,12n)
b) 23na(11p,12n)
c) 12c(6p,6n)
d) 55mn(25p,30n)

What are similarities and differences of reflection, refraction, diffraction and absorption?

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.

The ability to make things happen is also called a. heat b. force c. matter d. energy
