We are expecting to see that it decreases because it's feeling a stronger pull, all the electrons are being pulled in closer to the nucleus, so that atomic size is going to get smaller.
我们将看到它是减小的,因为电子会感受到越来越强的吸引力,所有的电子将会被原子核拉得越来越近,所以原子半径将越来越小。
She ran across the room, grabbed me by the hair, and lifted me off the ground,
她会穿过教室,走到我面前,揪住我的头发,把我拉起来,
Again, your common sense tells you, "Look, you are pulling something whose effective mass seems to be 5, the answer is 2."
你的常识会又一次告诉你,"你在拉一个相当于 5 千克的物体,所以加速度是 2 "
If you are playing a downbeat with an up-bow are you in good shape? No, no, no, no.
如果你用上弓去拉重音,你的形状会好吗,不会,绝对不会
So because we're feeling a stronger attractive force from the nucleus, we're actually pulling that electron in closer, which means that the probability squared of where the electron is going to be is actually a smaller radius.
因为我们能感到来自原子核,的更强的吸引力,我们实际上会将电子拉的更近,那意味着电子运动的,概率半径是,事实上是一个更小的半径。
Nicola, if you didn't think you'd get caught, would you pay your taxes?

The problems are set up so that, if you start down the right path, it should be pretty straight-forward to work it through If you start down a plausible but incorrect path, you can sometimes find yourself stuck in the weeds somewhere, and we want to bring you back in.

玛拉将是你们的课后辅导老师,她会批改你们上课前交给她的作业,课后她会将批改后的作业发还给你们
If I pull the one kilogram mass and I let it go, it does something, some acceleration.
如果我拉 1 千克重的物体并松手,就会获得一个加速度
But for any procedural things, like, you know, this problem set was not graded properly, and so on, there's no point e-mailing me because I'm going to send it to Mara anyway.
但是任何程序上的问题,比如,这次的作业判得不对 等等,这些情况给我发邮件是没有用的,因为我还是会直接转发给玛拉
