And what we end up with for the energy then is 2.84 times 10 to the -19 joules.
我们算出的能量是,2,84乘以10的-19次方焦耳。
And then we have c, the speed of light, 2.998 times 10 to the 8 meters per second.
然后我们知道光速等于,2,998乘以10的8次方米每秒。
And again, we're not saying choosing 2 beats choosing 1, 2 wins against 1 or 9 wins against 10.
我们不是说选立场2会击败选立场1的,选立场2能赢立场1的,或者选立场9能赢选立场10的
You get 2.18 times 10 to the plus 6 meters per second, 1% which is about 1% of the value of the speed of light.
。18*10^6米每秒,得到的速度大概是光速的。
Last year 2006, India's economy 9.2% grew at 9.2%, not far below China's 10.7%, making India the world's second fastest growing economy.
去年,也就是2006年,印度经济的增长速度达到,接近中国10。7%的经济增长速度,使印度成为,世界第二大高速发展的经济体。
Here I got 3 kg and I got 2 kg and I'm pushing with 10 Newtons and I want to know what happens.
一个物体 3 千克,另一个 2 千克,现在我用 10 牛的力推它,我想知道接下来会怎样
Right now, we have them scheduled at 9:00, 10:00, 11:00, 12:00, 1:00, and 2:00.
现在我们就安排他们分别在,九点,十点,十一点,十二点,一点,和两点。
Listen, the two periods in American history 1945 1890 to 1945 The economy suffers 3 contractions of 5 percent, 15% 2 of 10, and 2 of almost 15 percent.
听好,美国历史上的两大时期,第一时期是从1890到5,经济遭受过三次紧缩率为5%的经济紧缩,两次10%,还有两次高达。
Roger Ibbotson took a look at a larger group of funds -3,500--funds over a ten-year period and found survivorship bias at 2.9% per year and backfill bias at 4.6% per year.
罗杰·伊博森研究了更大的样本组,3500支基金10年间的表现,算出其生存偏差是每年2.9%,回填偏差是每年4.6%
10kJ/K That's the heat released, divided by minus 10 or 10 kilojoules per Kelvin, right. It's 8.2 Kelvin.
再除以-10,或,这就是8。2K,换句话说。
So for every photon we have 2.84 times 10 to the -19 joules.
每一个光子有,2,84乘以10的-19次方焦耳。
So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.
我们一共有2,4,6,8,10个价电子,所以我一边填一边要确认,我数到10。
So what we end up with for the number of photons in this laser beam of light is 2.1 times 10 to the 17 photons.
这个激光束的数目是,2,1乘以10的17次方。
*10^-18 1.6 times 10 to the minus 18, excuse me, 6*10^-19 we have 1.6 times 10 to the minus 19, 2.18 times 10 to the minus 18, etc.
。,1。,2。18*10^-18,等等。
We put all of this over the Rydberg constant, which is 2 . 1 8 times 10 to the negative 18 joules, and we want to raise this all to the 1/2.
除以里德堡常数,我们想把这些所有的再开方,所以我们最后。
So 2/10 of a percent, 2/10 would be the move here.
所以这里的移动量就是,一个百分百的。
I got 2 kg and I pull this guy with 10 Newtons.
还有一个 2 千克的物体,我用 10 牛的力来拉它
So we know that 2 is not dominated, and particularly not dominated by 3, When you delete the dominated strategy of 2 dominating 1, or 1 being dominated, when you delete that and 10, then it is.
我们知道选立场2并不是劣势策略,它并不劣于选立场3,当你剔除劣于策略2的劣势策略1,或者说立场1处于劣势,当你剔除策略1和10之后,2就变成劣势策略了
You add the two, you get 10 = 5a and you get a = 2.
把两个方程相加,你就会得到 10 = 5a 算出 a = 2
Now, I don't have to fill my head 6 with 2.18 times 10 to the minus 18. 13.6, that's a cool number. I can remember that.
现在,我不需要记住,2。18乘10到负18,13。,那数字太给力了,我可以记住它。
And if we do that calculation, what we find out is that the binding energy, in this case where we have no shielding, 72× is negative 8 . 7 2 times 10 to So, let's compare what we've just seen as our two extremes.
我们会发现结合,能在这个情况中,没有屏蔽,等于-8。,所以我们来对比一下,我们在两个极端的案例中看到了什么。
This thing does 2 gig worth of operations.
G就是10的9次方。
Now you can see 2.18 times 10 to the minus 18 joules can be 13.6 eV.
你可以看到,2。18乘10到负18焦耳,得到13。6电子伏特。
