An unsuspecting tourist takes an electric razor designed to operate with 120-V electricity to Europe and plugs it into a 220-V outlet. (A special adapter is needed to do this.) The razor is ruined by overheating. If the razor normally consumes 20.0 W of power, how much power does it consume using 220-V electricity?

Suppose that an alpha particle with a charge of  C is moving with a velocity of
