Suppose the disk in the example has a hole cut out of it from its center, forming an annulus. The inner radius is r = 6.0 cm, and the outer radius is R = 15.0 cm. What is the potential (in V) of the disk at point P a distance of x = 23.0 cm from the center of the disk along the x-axis? The uniform surface charge density of the disk is 30 nC/m2.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

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.
