A card dynamometer

1.

Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card

mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards

bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2. A. When chemical reaction occurs, the more metal atoms lose electrons, the stronger rection ability is not necessarily. For example, the property of gold: magnesium > aluminum, so a is wrong
B. the rection of metal cations does not necessarily lead to the formation of metal elements. For example, iron ions are reced to ferrous ions, so B is correct
particles with the same number of protons, such as water and neon, are not necessarily atoms of the same element, so C is wrong
D and sodium peroxide can only react with acid, belonging to peroxide, not alkaline oxide, so D is wrong.
b is selected

3.

More than 500W power supply

sapphire rx580 full load power to more than 200 watts, plus CPU and other hardware power consumption, need more than 500 watts of power supply

If the power supply is

500, it is necessary to pay attention to whether it is rated power. The value of rated power is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical appliances may be damaged; If the actual power is less than the rated power, the graphics card can not operate normally

extended data:

the power of power supply can be divided into rated power, maximum power and peak power

rated power: the ambient temperature is between - 5 ~ 50 ℃, the input voltage is between 180V ~ 264v, and the power supply can stably output power for a long time

maximum power: at room temperature, when the input voltage is between 200V and 240V, the power supply can stably output power for a long time, and the maximum power is generally about 15% higher than the rated power. For example, the rated power of Xingu nuclear power 325pq is 250W, and the maximum power is 287w, which is close to 300W

peak power: the maximum power that the power supply can achieve in a very short time, and the time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, which is not a definite value, but the peak power can be very large, which is very easy to mislead users. For example, the rated power of Xingu nuclear power 325pq is 250W, and the peak power reaches 350W. Obviously, only the rated power and maximum power have practical significance

4. A card didn't play much
n card is better. Can change, give to add money to change n card
but the system needs to be reinstalled once. Because the system has recognized the graphics card

6. This company is the key company of Yunnan gold. They won't cheat people.

8. It's long gone from the gold standard, so it won't be linked to metals
the specific issue volume is calculated, and the amount and plan of issue are formulated by the people's Bank of China. And this quantity is generally calculated according to the money demand in economics, money demand = money circulation speed * commodity price. The velocity of circulation is generally a constant, and the price is generally based on the statistical results
in addition, the amount of foreign exchange in China will be converted into famous currency according to the exchange rate.
