The standard of living of any country means the average person's share of the goods and services which the country produces. A country’s standard of living, therefore, depends first and foremost on its ability to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy, “goods” such as food and clothing, and "services" such as transport and entertainment.
A country's ability to produce wealth depends upon many factors, most of which have an effect on one another. Wealth depends to a very large degree upon a country's natural resources, such as coal, gold, and other minerals, water supply and so on. Some regions of the world are well supplied with coal and minerals, and have a fertile (肥沃的)soil and a favorable climate; other regions possess perhaps only one of these things, and some regions possess none of them. The USA is one of the wealthiest regions of the world because she has vast natural resources within her borders(边疆), her soil is fertile, and her climate is of great variety. The Sahara Desert, on the other hand, is one of the least wealthy.
Next to natural resources comes the ability to turn them to use. Sound and stable (稳定的)political conditions, and freedom from foreign invasion(侵略), enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country equally well served by nature but less well ordered.
Another important factor is the technical efficiency(效能) of a country's people. Old countries that have, through many centuries, trained up numerous(无数的) skilled craftsmen and technicians are better placed to produce wealth than countries whose workers are largely unskilled.
Wealth also produces wealth. As a country becomes wealthier, its people have a large margin(富余)for saving, and can put their savings(储蓄) into factories and machines which will help workers to turn out more goods in their working day.

电子所带电量最早是由美国科学家密立根通过油滴实验测出的.油滴实验的原理如下图所示,两块水平放置的平行金属板与电源连接,上、下板分别带正、负电荷.油滴从喷雾器喷出后,由于摩擦而带电,油滴进入上板中央小孔后落到匀强电场中,通过显微镜可以观察到油滴的运动情况.两金属板间的距离为d,忽略空气对油滴的浮力和阻力.

(1)调节两金属板间的电势差U,当u=Uo时,使得某个质量为ml的油滴恰好做匀速运动.该油滴所带电荷量q为多少?

(2)若油滴进入电场时的速度可以忽略,当两金属板间的电势差u=U时,观察到某个质量为m2的油滴进入电场后做匀加速运动,经过时间t运动到下极板.若此油滴所带的电量的电性与(1)相同,求此油滴所带电荷量Q.
