In some region of space, the electric field is given by E = Axi + By2j. Find the electric potential difference between points whose positions are (xi, yi) = (a, 0) and (xf, yf) = (0, b). The constants A, B, a, and b have the appropriate SI units. (Use the following as necessary: A, B, a, and b.)

Which is not a step in the rock cycle?

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.

What happens to the vapor pressure of a substance when its surface area is increased at constant temperature?
