1) If the frequency of a wave decreases what does that tell you about the energyof the wave? 2) if the wavelength of a wave increases what happens to the energy of the wave?

What is the radius of the circular path ofa charged particle in a magnetic field?

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.

Most of the volume of an atom is occupied by the
