Find the physical order of magnitude The form of a few cubic meters of 10 tells me: the size of the electron cloud, asteroid belt stars (sun) planets The form of a few power seconds of 10 tells me: the time of a pulse, a day, a year, the life span of a person, the age of the earth, the age of the galaxy All of the above know that you can tell me 10 times

The form of a few cubic meters of 10 tells me: - 10 the size of an electron cloud asteroid belt star (sun) planet
The form of a few power seconds of 10 tells me: the time of 0 pulsating once a day, a year, the life span of people, the age of the earth, the age of the galaxy

What is the order of trillion
one hundred and twenty-three

There are two answers
100 million = 100 million
1 trillion = 100 million (the 12th power of 10)
1 trillion = 1 million (the sixth power of 10)
In Lesson 12 of Esperanto textbook published by China News Agency, "how much is a trillion", it is clearly said that a trillion is milion oble miliono = biliono (one million, that is, the 12th power of 10). To count this trillion, if you count 200 per minute, it will be 12000 per hour, 288000 per day, 105120000 per year, and count one trillion, It will take more than 9500 years. How many generations will it take to relay this number? This one trillion is one trillion. It is more than 769 times of China's 1.3 billion population. However, we often encounter "trillion" in our daily work. For example, there are "megahertz" of frequency, "megaohm" of resistance and "megapa" of pressure in radio. However, the "trillion" in modern science and technology is not "trillion", but "million", that is, miliono, It's one millionth of a trillion. In other words, the difference between the two "trillions" is one million times. If we count the latter trillions according to the above method, it will only take about three and a half days to count them!
Who is right? In fact, they are all right. What's the matter? Because they come from different counting systems in ancient China. There are three systems of counting methods of more than 100 million in ancient China: These are recorded in the book "Shu Shu Ji Yi" in the Eastern Han Dynasty
One is Shangfa, which is a self multiplying system: ten thousand is ten thousand, one hundred million is trillion, and trillion is Beijing. Archimedes of Greece also used this system: 104 = ten thousand, 108 = one hundred million, 116 = trillion, and 132 = Beijing
The second is China and France, which are the ten thousand progressive system. They are all progressive by ten thousand: ten thousand trillion yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan
In modern times, until the liberation of China, the decimal system was still popular, that is, a ten trillion trillion trillion jingcuanzigou (Tubian) stream was carrying reports, all with decimal, 100000 as billion, 1 billion as trillion, 10 trillion as Beijing; 10 ^ 4 = 10000, 10 ^ 5 = billion, 10 ^ 6 = trillion, 10 ^ 7 = Beijing
The "trillion" used in modern science and technology belongs to the third method, which is 10 ^ 6, that is, one million. For example, megacycle (MHz) megaohm (m Ω) megawatt (MW)... While the modern "billion" belongs to the second method, that is, China and France (which is also consistent with the "billion" in the first method). 1.3 billion is equal to the eighth power of 13 times 10, not the fifth power of 10
In general, in order to avoid confusion, "trillion" is only used for 10 ^ 6, while "trillion" is used for 10 ^ 12. The largest number is "trillion", "trillion", "billion", "billion", "billion"

How many pieces can you cut the iron plate 120 cm long and 80 cm wide into the largest square with no surplus?

Is to find the greatest common factor of 120 and 80
It's 40
So, the side length of a square is 40 cm
There are 120 △ 40 × (80 △ 40) = 6 squares

When a helicopter takes off vertically from the ground at acceleration a, the fuel consumption per second is known to be v = PA + Q (P.Q is a constant). Now, if the helicopter wants to accelerate to altitude h, and the fuel consumption is the least, how much acceleration should it take up? In this case, what is the minimum fuel consumption?

H=0.5at²
Fuel consumption v = VT = (PA + Q) t = (PA + Q) √ (2H / a) = [(P √ a) + (Q / √ a)] √ (2H) ≥ 2pq √ (2H)
When p √ a = q / √ a, take the equal sign
a=q/p

If a sector with radius of 10cm and center angle of 216 ° is used to make the side of a cone, the height of the cone is______ cm．

As shown in the figure: the circumference of a circle is the arc length of a sector. The formula n π R180 = 2 π x, and ∵ n = 216, r = 10, ∵ (216 × π × 10) △ 180 = 2 π x is given. The solution is x = 6, H = 102 − 62 = 8. So the answer is: 8cm

The circumference of a circle is 12.84 cm longer than its diameter. How many square centimeters is the area of the circle? (solved by equation)

Let the radius be X
2x （3.14-1）= 12.84
x= 12.84÷（3.14-1）÷2
=6÷2
=3 cm
Area: 3.14 × 3 × 3 = 28.26 square centimeter
