If you don't need the best of the best, you can get an even better deal. There are countless smartphones that cost between $100 and $300. They mostly range from passable to good, but some stand out: The very good $180 Moto G, for one, is an unbelievable deal for the price. 5) Consider buying a used phone.f you don't need the best of the best, you can get an even better deal.

e. On Venus, the difference between the sidereal day (243 Earth days) and the solar day (117 Earth days) makes clock times meaningless. A rotational day on Venus takes about 5832 Earth hours. A sunrise-to-sunrise day takes about 2802 Earth hours. Using either to design a clock would not be practical.
Again, Earth is at 1.0, and Venus is at 0.72 AU. Then: (1.0 - 0.72) x 8 1/3 = 0.28 x 25/3 = 2 1/3 light minutes. As you can see, the same method can be used for all the distances you require, and the math is pretty basic.
