This is Hong Tao's latest movie. I like Hong Tao. He has made many good movies over the years. Unfortunately, this is his worst movie. If you want to have fun, stay at home and watch TV

If you knew a bottle of water had been recycled from urine, would you drink it? Aspergillus at the
International Space Station (ISS) may soon do so.
NASA said it would use a high-tech machine to recycle water
at the ISS.The Machine will recycle everything from sweat, the water for washing hands, shower water,
water used for brushing teeth,and even urine,to make drinking water.
It will save NASA millions of dollars each year.At Present, each ISS astronaut uses about 4.4 liters
of water every day.It costs about $24 million a year to transport water up to ISS.NASA says that a liter of
water costs about $11,000.
The machine will be sent to the ISS in October 2008.NASA hopes it will recycle about 93% of all water
used on the station.
Will the water be clean?Scientists say the wastewater will go through a very complicated process
For example,different chemicals will be put in the wastewater; the water will be heated to 130℃ to
Get rid of bacteria. The recycled water is thousand of times better than the water from a city tap,
scientists say.

It will save NASA millions of dollars a year. Currently, each astronaut on the international space station uses about 4.4 liters a day
It costs about $24 million to transport the astronauts' annual water consumption to the international space station. NASA says it costs about one liter
The shipping cost of water is about $11000
The machine will be sent to the international space station in October 2008. NASA hopes it will recycle about 93% of all water used by the station
Is the recycled water clean? Scientists say that the sewage will go through a very complex process. For example, different chemicals will be put into the wastewater; the water will be heated to 130 ℃ to eliminate bacteria. Scientists say that the recycled water is thousands of times better than the city tap water

The specific charge of the electron is 1.6 times 10 to the 11th power C / kg, and the mass of the proton is 1840 times that of the electron. What is the specific charge of the proton?
Physics elective course 3-1 problems of charge and its conservation law

An electron is a quantity of charge, negatively charged,
A proton is a quantity of charge, positively charged
Let the mass of the electron be a and the mass of the proton be 1840a,
The specific charge of electron is: e / a = 1.6 * 10 ^ 11,
Then, the specific charge of proton is: e / 1840a = (E / a) * (1 / 1840) = 8.7 * 10 ^ 7
That is, the specific charge of proton is 8.7 * 10 ^ 7C / kg

The inequality ax ^ 2-2ax + A ^ 2-1 = 0 (a is not equal to 0)

Ax ^ 2-2ax + A ^ 2-1 = 0 (a is not equal to 0)
a(x^2-2x+1)=1-a
a(x-1)^2=1-a
(x-1)^2=(1-a)/a
X = 1 + radical (1-A) / a (a is not equal to 0)
Or 1-radical (1-A) / a (a is not equal to 0)

Passive voice: no speaking out loud in the library

It is not allowed to speak aloud in the library. 3. You must't speak aloud in the library. 4. Please keep quiet in the library

1. Generally, we stipulate that the right is the positive direction, and the selection of () depends on the actual situation
2. Can all rational numbers be represented by the points on the number axis? Can all the points on the number axis represent rational numbers?
3. On the number axis, there are () points of 2 unit length away from the origin, which is ()
4. Please tell which side (left and right) of the origin is the point representing the following numbers on the number axis, and how many unit lengths are there from the origin? Negative one third, negative two point four, three point two, one third and two point five
5. The largest negative integer is () and the smallest positive integer is ()

1. (determination of unit length)
2. Yes, the points on the number axis are not only rational numbers, but also irrational numbers
3.2 -2
4. Left one third, left two point four three point two, right one third and two point five
5 -1 1

F (x) = x & # 178; - 4 / x + 2, G (x) = X-2 {x | x ≠ - 2} ask whether it represents the same function?

Yes
The same function only satisfies two points
1. The domain of definition is the same
2. The form of the simplest result is the same
The definition fields here are all x ≠ - 2
The results are all X-2

On Sunday morning, I played all day at my classmates' home

Just remove the word "morning"
