Note that this is the maximum possible kinetic energy because W is the minimum energy necessary to liberate an electron. The threshold frequency, the minimum frequency the photons can have to produce the emission of electrons, is when the photon energy is just equal to the work function: The Compton effect Although photons have no mass, they do have momentum, given by:
Conclusion: The most reliable cars. While these two surveys may vary, it is evident that cars made by Toyota (including Toyota, Lexus and Scion, have a generally impressive record on reliability, so are a good place to start if you are looking for a reliable car. In terms of American-made cars, Buick comes out top.
Audi R8. The Audi R8 also makes the list for one of the most reliable supercars. Not only is it reliable it is also the most livable supercar on this list. The first-generation R8 is on its way out and Audi is preparing to launch the second-generation model in the very near future.
