The mechanical advantage of the wheel and axle is the ratio of the distances from the fulcrum to the applied loads, or what is the same thing the ratio of the diameter of the wheel and axle. A major application is in wheeled vehicles, in which the wheel and axle are used to reduce friction of the moving vehicle with the ground. Other examples of devices which use the wheel and axle are capstans, belt drives and gears.
 Question: is a car an example of a wheel and axle Context: Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Thus, if the molecular weight of one gas is four times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate of the other (heavier gases diffuse more slowly). A complete theoretical explanation of Graham's law was provided years later by the kinetic theory of gases. Graham's law provides a basis for separating isotopes by diffusion--a method that came to play a crucial role in the development of the atomic bomb.
 Question: is there a relationship between molecular weight and diffusion rate Context: Soul Surfer is a 2011 American biographical drama film directed by Sean McNamara, based on the 2004 autobiography Soul Surfer: A True Story of Faith, Family, and Fighting to Get Back on the Board by Bethany Hamilton about her life as a surfer after a horrific shark attack and her recovery.

Daniels co-created Parks and Recreation with Michael Schur, who had been a writer on The Office. The two spent months considering ideas for the new series and debating whether to make it a stand-alone show rather than a spin-off. According to Daniels, they eventually abandoned the original spin-off plan because they ``couldn't find the right fit''. They considered a series about a local government official trying to rebuild a political career following a humiliating public spectacle. They eventually abandoned the idea, though it did end up being incorporated into the backstory for Ben Wyatt late in the second season. After Amy Poehler agreed to play the lead, they decided the show would revolve around an optimistic bureaucrat in small-town government.
