It turns out, and we're going to get the idea of shielding, so it's not going to actually +18 feel that full plus 18, but it'll feel a whole lot more than it will just feel in terms of a hydrogen atom where we only have a nuclear charge of one.

结果是我们会有,屏蔽的想法,所以它不会是完整的，但是它会比原子核电荷量,吸引力要大很多,只有1的氢原子的。

So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.

抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它，我们从原子核中留下的，全部有效电荷就是，所以，在我们的第一个例子中,我们的第一种极端情况。

If I reduce that it would be 3 plus t of b minus 3, so in general 3*k+t this is 3 k plus t of b minus k. OK.

把b减去一个,在外面加个3就可以了,因此也就是。

So y=y0+5 meters, and that was the height to which it rises.

因此y=米,这就是它会上升的高度

I personally don't like swings that much and it's the B-/B+ range, so I'd much rather prefer that to a swing from A to C, and that's my reason.

我不喜欢成绩波动很大的,比如B-/B+这个范围,所以我还是喜欢像A到C这样小点的,这就是我的原因

So basically the idea is that the more these firms produce, so the more the total quantity produced q1 + q2, the lower is the price in the marketplace for this product.

核心思想就是两家企业生产得越多,即产量,q1 + q2,越大,该产品的市场价格就越低

Okay, so the final answer is that x=x0+v0t+at^/2.

最终的结果是,x=x0+v0t+at^/2
