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.
Toyota has built its reputation by offering inexpensive cars with a low cost-of-ownership and, usually, high safety ratings. And with the closing of the Scion brand, Toyota has added a few cars to its lineup that cater to younger buyers. Least Expensive: The Yaris lineup is the least expensive offering at Toyota, with the two- and four-door hatchbacks plus the Mazda-sourced Yaris iA sedan all carrying base prices under $17,000. Sportiest: As Toyota shutters the Scion brand, the brandâs FR-S has been renamed the 86 for the Toyota lineup.
