What happens to the frequency response of a p23dd sensor , 6f, 1m, water filled catheter system (at 20 ˚ c) when a tiny pinhole leak occurs at the junction of the catheter and sensor? the leak allows a .40 ml/min flow for a pressure head of 100 mm hg (13.3kpa). plot frequency response curves for the system with and without the leak.

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 determines the amount of inertia an object has

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
