C
Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions(排放) vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators(发电机). Generators are fueled by something--usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal
(地热) plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. It’s just because the coal is burned somewhere else, it looks clean. It is not. It's as if the California Greens are covering their eyes—“If I can't see it, it's not happening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat—at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far—so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from nukes or geothermal, or hydro or wind or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.
In addition electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.

(2)小明在图甲中，保持金属盒深度不变，改变橡皮膜朝向，目的是为了探究液体内部压强大小与 是否有关；
(3)小明还猜想液体压强与液体深度和密度有关。他在图甲基础上，继续将金属盒下移一段距离，发现压强变大。若接下来又进行了图乙所示实验，再与图甲比较， (填“能”或“不能”)得出液体压强与液体密度有关的初步结论。
9、在利用生活中的小物件做实验的实践活动中，小明利用一个空矿泉水瓶做实验：

(1)为了探究液体压强与深度的关系：小明在空矿泉水瓶的侧壁不同的深度开三个小孔，然后装满水拿起来，水从小孔射出，如图所示，这个现象说明了：液体压强随深度增加而 ；
(2)水从瓶子射出是水的 能转化成动能；
(3)小明发现：
