... Result: Average molecule weight of water vapor is 18, whereas the molecule weight of dry air is 28. As the gravitational force effects the objects in proportion to their densities, by being behind the dry air, the vapor moves up and remains in an area where the density is equal to its density. The ...

... with reference to the falling book (Figure 9-2). The work done by gravity is given by eq[9-4]. This value depends on the endpoints of the book’s travel (ya and yb) and not on the path taken. So according to description 2, the force is a conservative one. Moreover, none of the book’s initial potentia ...
