The force, as this weight drops is constant, mgh and so the work is just going to be m g h, h where this is h.

当重物掉落时候的力是恒定的，因此做功就是，这段长度是。

So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.

比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。

Problem 2B is asking you to find the point at which h equals 2200, x=0 partial h over partial x equals zero 0 and partial h over partial y is less than zero.

题2B要求找到一点，在这点处，h等于，且∂h/∂,以及∂h/∂y小于。

Also in Kenya, a video game is being tested as another way to teach young people to avoid H.I.V.

So we'll take h 2 and we'll run -- or actually we'll have h 2 filled in an evacuated glass tube.

我们马上就会在氢原子上试一试,我们用氢气-我们把玻璃管充满氢气。

And now we're almost done, except what we H really want is delta H and not delta U, right.

我们差不多已经完成了,除了我们实际上想要的是Δ

It should be S-h-a-i-k-h or S-h-e-i-k-h, but not S-h-a-y-k-h, as it is in the subject line.
