Notice that the value stored can be any JavaScript object and in this example it is probably better to think of storing two string objects rather two string literals. The purpose of a pipe is to take in a value, filter that value, and return the filtered result. Follow along with instructor Bruce Van Horn, and learn how to build a class inside a reusable library, which is then consumed by a simple user interface.

If the angular speed at the bottom is 8. Python is an object-oriented language. For large objects moving at high speeds through air, the drag force is given by F d = C(rho)Av 2 /2, where v is the speed, A is the cross-sectional area of the object measured in a plane perpendicular to its motion, rho is the density of the air and C is the drag coefficient.
