Will the dust really be two billion years old, and how much area will two billion yuan occupy?

Yes, because light travels in a straight line, we can see an object because of the diffuse reflection of the surface of the object, and if there is no dust in the void, then our world will be gray. Can't see clearly. In addition, volcanic eruptions were frequent in the early stage of the earth, spewing out a lot of magma, and yes, there was a lot of dust in the air.

Under normal circumstances, the air is colorless and transparent, and it is difficult for us to see the impurities in the air inadvertently with the naked eye. If a ray of sunlight shines into the house, you can see the originally transparent air, under the irradiation of the sun, the dust is refracted and reflected by the light, and obviously floats in the air, large and small, dense. According to scientific statistics, in the indoor environment, the number of dust particles greater than the above in every cubic meter of air is about 40 million 50 million.

And there are countless bacteria attached to the dust particles.

Under the action of the air compressor, if the heat exchange with the outside world is not considered, according to the calculation of the relevant formula, the volume of m3 air in the original atmospheric pressure state is finally compressed to 1m3 when compressed to gauge pressure. This process alone tells you that the compressed 0A gas with a pressure of 8MPa will have 192,000,000,240,000 dust particles per cubic meter.

In addition, in the process of compression, the atmosphere brings in lubricating oil and mechanical abrasive debris from the air compressor. According to the principle of air thermodynamics, a large amount of supersaturated water vapor will be re-reduced to water droplets after compression.

Yes, and seemingly extremely soft dust is more likely.

Who is Dust? I'm going to call ** and ask him if it's okay, hahaha I'm smart.

I don't know anything.

Extended information: The fifth set of renminbi has 6 denominations of 1 yuan, 5 yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan, of which 1 yuan has 2 kinds of banknotes and coins. According to the needs of market circulation, the fifth set of renminbi has increased the denomination of 20 yuan and abolished the denomination of 2 yuan, making the denomination structure more reasonable.

The fifth set of renminbi inherits the traditional experience of China's printing technology, draws on the advanced technology of foreign banknote design, and has greatly improved its anti-counterfeiting performance and adaptation to the modernization of currency processing. The front of each denomination currency adopts the head of the chairman in the early days of the founding of the People's Republic of China, the backing adopts the famous Chinese flower pattern, and the main scene pattern on the back fully expresses China's long history and magnificent mountains and rivers through the selection of representative patterns with national characteristics, and promotes China's great national culture. Since August 31, 2005, the People's Bank of China has issued the fifth set of RMB in the 2005 edition, the main pattern is the same as that of the 1999 edition, but the position of the variable digit and denomination watermark has been adjusted, and gravure touch lines, anti-copy marks, and the suffix "yuan" have been added to the denomination number on the back.

It's normal for celebrities to be rich, just a movie, advertising endorsement, and performance have a lot of money.

But if you don't have real skills and influence, that is, the scenery for a few years, you can't be remembered for a long time.

If you have money, you can't spend it, and if you have a life, you can't spend it, and if you have a life, you can't spend it. I would choose the former and leave my property to my children and grandchildren.

Choose two billion, add twenty years old, and there are still twenty years to do.

For today's people, they may generally choose 2 billion, after all, people nowadays are always greedy in the majority.

The first one, because if I had so much money, I would first do a little more good deeds for the society and my hometown, and finally leave a name for eternity, and it would be worth dying.

If I mean if'If you have to choose 1 of 2'Then I'll choose the former!

Of course I want 2 billion, I still have to think about it.

It depends on the angle you stand on.

Everyone wants something different

You can see how much the world is about people.

Life is in **, so I lived.

I think there is, so everyone loves money Ask: Alas, what's wrong with people now, love money also has a bottom line, it's very incomprehensible, I have lived for more than 30 years, and the current China is unreasonable. Beg.

Based on the exchange rate on January 2, 2020, 2000000000 won = Chinese yuan.

1. Currency exchange:

1 won = Chinese yuan.

1 RMB = South Korean won.

For example, if a bottle of mineral water is 3 yuan, you need KRW: 3*KRW = KRW;

A bucket of instant noodles costs 800 won, and you need RMB: 800 * RMB = RMB.

1 won = Chinese yuan.

2 billion won = 10.95 million RMB.

1 won = Chinese yuan.

2 billion won = 10.95 million yuan, dear.

Hope it helps.
