Ant mining machine S9 how much a day to dig

S9 computing power 13.5T, the current network computing power 6.39eh/s, 1e = 1024p, 1p = 1024t, 1t = 1024g, a S9 a day to proce bitcoin is [13.5 / (6.39 * 1024 * 1024)] * 180 ≈ 0.0036btc< br />

2. Mining is definitely the first professional mining machine. Many new children's shoes will choose to use the graphics card to mine, but the graphics card mining is just like doing a professional job with the "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

4. Bitcoin, in short, is an internationally recognized virtual currency. In some foreign countries, bitcoin can be used to trade; In China, it was also announced a while ago that bitcoin withdrawal might be tried out
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it

5. Whether to consider gravity depends on your specific problem. The simplification (modeling) process of practical problems is very important, which has a lot to do with your professional skills. Once the modeling is completed, it basically determines the ANSYS analysis method, unit type, etc. It also determines whether gravity is considered in the analysis. For example, in a truss structure, if the bar only bears the axial force, the gravity is not considered in the analysis, and the link series element is used; If there are other loads (at the non connection point) besides the axial force, the beam series elements may be used instead of gravity.

6. In the standard physics problem, the value of acceleration of gravity must be taken according to the requirements of the problem when it tells you how much to take, and g = 9.8m/s ^ 2 must be taken when there is no explanation.
if there is no explanation in your problem, then G = 9.8m/s ^ 2 is taken to calculate, and the result is
velocity when t = 3S
V = GT = 9.8 * 3m / S = 29.4m/s
kinetic energy at this time
e = 1 / 2 * MV ^ 2 = 1 / 2 * 3 * (29.4) ^ 2
J = 1296.54j

7. In fact, are more profitable, take dream said (other popular online games can be similar) ~ dream now hit a lot of people
in the New District, what other RMB players want is to stay offline for 24 hours. As long as you have a good reputation on it {use a trumpet to roar in various sects every day} you don't have to worry about finding players. The price is absolutely not low
and earning g-coin on it is also very promising. For example, you can use the number of the LED player to pick up the ring monster (running ring) - a kind of task. The leader of the task is sure to be no more than one of the monsters, but don't worry about the number in your hand, because since the player is asking you to help with the training, it must be RMB player, And RMB is very BT in general (except for a few) or the plot is strange, which makes a lot of money in the new area
there is also selling things. In dreams, you can open a shop to sell the monsters of the school (mission), or ring equipment. By the way, it takes time to open a shop, because it must be replenished frequently. It's very suitable for opening a studio. It's good for advertising, and it's guaranteed (99%).. There are many ways to make money, but it takes time.... If you are interested, you can find out
the profit of RMB in exchange for dream currency is absolutely reassuring. Of course, do any line can not guarantee 100% of the money, you have to explore first, then you can make money.. And the cost is not high, as long as you have someone who can do it at any time, so the probability of bankruptcy is relatively small~

8. It should be said that acceleration is calculated at any time. Only when the object is only subjected to gravity, the acceleration is the gravitational acceleration G
the acceleration of gravity g is a constant, which is only related to the position of the earth; When studying the motion of objects, the acceleration of gravity has no meaning. In the calculation, everything should be based on the acceleration

9. I don't understand this formula very well. It's too complicated... But there's a special explanation.... In addition, I will send you an easy to understand cross-country formula.... Here's the formula you want: I measure every centimeter on the screen as one meter, The acceleration of gravity of a wooden car in a tank baby with a 32 cm horizontal screen (17 inch CRT display) is 4.8. I didn't measure the acceleration of gravity of other cars, but it's very strange. From the physical analysis, the acceleration of gravity of bullets in all cars should be the same, but the actual situation is that each car is different. So I come to a conclusion: S = V2 * sin (2a) / 4.8, where V2 is the square of initial velocity It's not strange to throw. 2a is the angle of your firing multiplied by 2. Then some people will ask, how can v be transformed into a more intuitive force in the tank baby? Because of the time relationship, I only measured the principle of the wooden car, and the other cars are completely consistent. We can think that v = at and a = f / M (Newton's second law), so v = f * t / m, where m is constant and f involves angle, The main reason for the complexity of car type is that the car type has a great influence and the angle has little influence. The error caused by the angle is mostly quantitative error. Therefore, combined with the above, if the fixed angle is unchanged, it means that time controls the distance you play, that is, the length of time you play according to the space, but the measurement standard of T is not in seconds, but in the value of 1 ~ 4 (that is, the number of squares on the power bar) We can set up a linear function y = KX, where y = V, x = t, then K is required. We call k a proportional constant. After my calculation, the K of wooden cart at 70 degrees is 5.726, that is, y = 5.726x, 50 degrees is slightly different from 70 degrees, but the error is not big. The result will be mentioned below. For example, when the enemy is at the position of 1 screen, you use 70 degrees, then s = 32 to substitute the formula V2 = 32 * 4.8/sin (140) and square v2 We get v = 15.46 and then transform it to t, that is, t = 15.6 / 5.726 = 2.699 = 2.7, which is the common saying of 2.7 force. If it is 50 degrees, I find that the calculated force is 0.1 greater than the actual force, and there is no quantitative error. I don't know why if I think it's disgusting to watch the screen distance of 32, I can watch the half throw or other 40 30, but there is a proportional relationship between them Half throw is 1 screen 20, so the actual distance = half throw distance * 1.6 (actually 1.6 is obtained from 32 / 20, If you don't like the half throw, replace 20 with 30 40. The principle is the same. Then the formula of the windless wooden car hitting the position with a certain force is (based on the half throw distance): distance (1 screen, 20) = (k * force) 2 * sin (2A) / (4.8 * 1.6). The difference between other cars is that K and 4.8 are changed to (k * force) 2, where 2 means square. Let's talk about the way to measure the gravity acceleration of a certain car: select two cars and dig a 15cm deep hole with wood (17 inch CRT display is emphasized, and the screen should be adjusted accurately, Then change the car you want to measure, throw the No.1 bullet into the pit with a very light angle of 0 degrees, and press the stopwatch to measure the time from the muzzle to the depth of 15cm at the same time. Measure several times more to make the data more accurate. Then use a formula g = 2 * 15 / T2, T2 is the square of the time you just measured. Here comes g. then sort out all the formulas, After the simplification, the actual force of 70 degrees = SQR (distance * 0.365) SQR is the root sign, which means it is hard to beat. I mean that the actual force of 50 degrees = SQR (distance * 0.221) I have calculated by 0.1, so I don't have to - 0.1 any more. At the same time, I give you the calculation method of the turtle's basic force of 70 degrees and 80 degrees (also a screen of 20 equal parts) the actual force of 70 degrees = SQR (distance * 0.45) 80 degrees The actual force = SQR (distance * 0.841) may have a force error of 0.05, which is only for you to adjust. Here, if you only require the windless basic force point of a certain angle of a certain car, you can directly use the formula force = SQR (distance * coefficient) to calculate the coefficient with the basic force point corresponding to a known screen distance. Generally, as long as the original basic force points are right, you will not be wrong The distance doesn't have to be limited to a screen of 20. You can use whatever you like. Anyway, the coefficient is fixed. The suitable range of this method is variable angle calculation force, fixed angle calculation force to obtain the basic force point. There is no need to memorize the data to estimate the fuzzy force point. When using this method to deal with the fixed angle calculation force of ordinary cars, I found that the formula of force = SQR (distance * coefficient) can also be used The coefficient is only related to the size of the wind (of course, the type of car is also related) interested friends can go to test a set of fixed angle force calculation methods, so that the wooden mark 90 degree force control and other BT algorithms are born, creating conditions, and then off-road, very simple... I believe you can understand ~ ~ cross country play is divided into 80 degrees, 70 degrees and 50 degrees. In a simple understanding, the distance between tanks on a screen is called one screen. As we all know, the strength scale of a tank is divided into four grids, each of which is roughly divided into 10 invisible grids. For example, a grid and a half force is called 1.5 force; One and a half screens are called 1 / 2 screens (1 * 1 / 2 in the table). First of all, let X be the wind force. If it is 0 wind now, then x = 0, so you can ignore the above circle (that is, the wind force diagram). For example, the distance between me and my opponent is half screen, then the grid force is 2.0, that is, half grid force according to 70 degrees, If you use 80 degrees to calculate, you use 2.75 force. If it's 10 winds, then x = 10, blow straight to the left, and I hit from left to right, then it's against the wind. Then look at the circle. Is it 0.5 written on it? Then use 0.5 times x = 5, then half screen distance, use 70 degrees - 5 degrees = 65 degrees, use 2.0 force, why use - 5 degrees? Because the downwind + angle, upwind - angle (remember a mantra, downwind plus downwind minus) circle (wind chart) is 0.5, the wind is 10, so take 0.5 times 10 is equal to 5 degrees, so take 70 degrees - 5 = 65 degrees, downwind minus, so use 2.0 force to hit it ~ and so on, no matter what the wind, you should be able to forget it? In addition, you can see a few special wind points, such as 0.40.350.2. What do you mean by 15 + 10-15 10 -? For example, if the wind force is 9, then it belongs to 10 - (less than 10), then use 0.2 to multiply X. for example, if the wind force is 12, then it belongs to 10-15 (range), then use 0.35 to multiply X. for example, if the wind force is 23, then it belongs to 15 + (greater than 15), then use 0.4 to multiply X. In addition, if the wind force exceeds 20, if it is downwind, use the calculated distance slightly, If it's against the wind, it's a little bit important. There will always be some errors. I hope you can play the game according to your own experience and this table ~ PS: you must have good math scores and strong mental arithmetic ability. It's easy to not keep up with the calculation speed when you just start. The time of sum up is over. You'll get used to it after one day. If you're not good at math, you'd better bring a calculator, And then find people 1v1 practice a 500 plate is at least, otherwise how can become a master?

10. How does the Federal Reserve raise interest rates
the Federal Reserve is the Central Bank of the United States, and the Federal Open Market Committee is its monetary policy decision-making body. It holds eight interest rate meetings in Washington every year to decide the direction of monetary policy adjustment
after the meeting of the FOMC, the Federal Reserve will announce whether to adjust the federal funds rate (benchmark interest rate) and how much to adjust it, and influence the capital adequacy of the market through the operation of buying and selling government bonds in the open market, so as to make the overnight lending rate of banks tend to the set federal funds target interest rate. The loan interest rate in the market generally moves with this interest rate, such as the housing loan interest rate and other indicators
the interest rate decision of the Federal Reserve is mainly based on the trend of the US economy. Generally speaking, the policy objectives of the Federal Reserve are to maintain price stability and promote employment. If it expects that the future economy may tend to be weak and there will be downward pressure on prices, it is likely to adopt a more relaxed monetary policy, such as recing interest rates; On the contrary, it may adopt policies such as raising interest rates to tighten monetary policy
what is the possible impact of the Federal Reserve's interest rate increase
e to the different trends of global economies, there is also a differentiation of monetary policy. While the US Federal Reserve is about to open the channel for raising interest rates, Europe and Japan are still in an extraordinary period of quantitative easing
raising interest rates by the Federal Reserve is both good news and bad news
the bad news is that the increase of interest rate means that the supply of US dollar funds in the US market will decrease, the interest rate and the rate of return on funds are expected to rise, and some cross-border funds will flow back to the US. The U.S. dollar will rise, and the U.S. dollar denominated commodities, precious metals, and foreign exchange markets will fall
for some emerging economies, this may mean the outflow of funds, which may lead to the decline of local currency exchange rate. If foreign exchange reserves and other measures are insufficient, it may mean risks; But if you have enough reserves and pressure resistance, it's not a problem
the good news is that the Fed's interest rate increase means that the US economy is recovering strongly, and some economies' exports are expected to improve
the people's Bank of China (PBC) recently stated that in view of the concerns that the US Federal Reserve's interest rate increase may lead to the fluctuation of RMB exchange rate, the RMB exchange rate is conditional to remain basically stable at a reasonable and balanced level in terms of medium and long-term fundamentals< The impact of the Federal Reserve's interest rate increase is mainly as follows:
1. The decrease of money supply in the market leads to the decrease of funds in the stock market, precious metals and futures markets. It is often a graal process to raise interest rates, and the impact on the above assets is also negative in the medium and long term
2. The graal return of US dollar to high interest currency will increase the attraction of investors to us dollar assets, which is bad for other non US currencies, and the non US currencies will depreciate accordingly It also depends on the monetary policies of other countries, such as the two currencies that are raising interest rates at the same time. If the US dollar raises interest rates and the currencies of other countries remain unchanged, the currencies of other countries will depreciate and fall)
3. Monetary tightening reces the market's risk aversion sentiment and depresses the demand for precious metal safe haven assets
4. The money supply has decreased, the inflation level has declined, and the level of foreign investment in the United States has increased
5. The decrease of money supply and domestic consumption power may affect the sustainable development of domestic economy.
