Calculation by hand

1. Lightcoin calculator calculated for reference only, not necessarily real income, recommend several mining graphics card to you, hd7990 R9 290x gold slave miner data card R9 280x

2. The computing power of CPU is related to the number of CPU cores, the frequency of core and the ability of single clock cycle of core
the ability of double precision floating-point computing is commonly used to measure the scientific computing ability of CPU, that is, the ability to process 64 bit floating-point data

the processor supporting avx2 can perform 16 floating-point operations in one core and one clock cycle, Also known as 16flops
CPU power = number of cores x frequency of cores x 16flops
processors supporting avx512 can perform 32 floating-point operations in one core and one clock cycle, also known as 32flops
CPU power = number of cores x frequency of cores x 32flops

3. According to the official website of coin'an mining pool, BTC's calculation power has reached 1.75e, 36053 effective miners, ranking 11th at present, OK's calculation power is 6.89e, and Huo's calculation power is 4.75e. At present, there is still a big gap in the coin'an mining pool. However, as a bystander, you should have a unique vision. Looking at the ups and downs of the previous coin circle, the development and launch of various new technologies, although coin an is late, it can always make the latecomer rank first. It probably doesn't take long for this ranking to change.

4. Tragically, it should be less than 0.01 yuan

5. Newton's second law of motion: force = mass × Acceleration, force must know mass and acceleration

6. I think the richest man can still listen to it. Ma Yun says that he is very optimistic about the chain of blocks, and bitcoin may be a bubble. After a period of depression, bitcoin once again ushered in a big rise. Now that the big guys have spoken, let's take advantage of the recent sharp drop in bitcoin and hurry to enter. Novices can go to okex to open an account, and their new tutorial is very good.

7. It can't be said to be a scam. The starting point of operation is good at the beginning, but bitcoin is only virtual currency after all, although it has certain value; There are so many currencies that can be traded in the foreign exchange market. They are all safe and formal. Why should we take risks to invest in virtual currencies? To be honest, foreign laws can do anything, as long as you bear the consequences; I believe that you come to invest for the sake of investment income. Why not consider safe investment and take risks. Now there are so many foreign exchange market platforms, it's not very good to choose a safe, formal and reliable platform, such as Fuhui Jiasheng KVB, Kunlun international, etc? Deception doesn't matter. What matters is whether anyone is cheated

8. Because it is a standard cuboid, the center of gravity is in the center of the object, so:
F = 22000 ÷ 2 = 11000 (KGF)

9.

Intelligence quotient (IQ) = intelligence age / actual physiological age, and then multiply by 100. For example, the intelligence age of the child measured by the scale is 3 years and 6 months, and the actual age on the test day is 3 years, then IQ = 42 * 100 / 36 = 117

the distribution of intelligence quotient of Stanford Binet scale: 140 or above is excellent (genius); 120-139 were excellent; 110-119 are superior and intelligent; 90-109 is medium; 80-89 were middle and lower; 70-79 is critical intelligence deficiency; Below 69 is mental retardation

There are two types of high segment IQ test: Graphic logic and digital logic. It is mainly designed to test IQ higher than ordinary people by more than two standard deviations; At the same time, it is also the entrance test of some high IQ associations

the reason for the design of these high segment tests is that although the range of Wechsler intelligence test in general hospitals is before 40 to 160, the test subjects are mainly people with IQ of 70-130, and the designers also admit that people who deviate from the average level are not suitable for this test. This kind of high-level intelligence test is very difficult, with no options and unlimited time, which is a common feature of most high-level intelligence tests

the questions of digital logic and graphic logic do not involve the acquired knowledge, but only test the innate intelligence level

extended data:

there are two kinds of IQ tests that are still widely used: Stanford Binet test and Wechsler test

The most widely used models are Stanford Binet test and Wechsler model. As of July 2014, the number of norm data has exceeded 7.9 million. Through the scientific presentation of the average IQ of different groups (randomly selected big data results in proportion)
