1. Before calculating the friction force, we must first analyze the motion of the object to determine whether it is static friction or sliding friction. If it is sliding friction, we can use the formula F= μ N calculation, where μ Is the coefficient of friction; If it is static friction, it is generally based on the motion of the object (static, uniform motion, or variable speed motion), In order to determine the direction of sliding friction, it is necessary to grasp the judgment basis of "the direction of sliding friction is opposite to the relative movement direction of the object". The specific method is: first select the object subject to friction as the research object, and then take the object directly in contact with the research object as the reference object, Find out the velocity direction of the research object relative to the reference object, then the direction of the sliding friction is opposite to the direction of the relative velocity.
the basis for judging the direction of the static friction is: "the direction of the static friction is always tangent to the contact surface, and is opposite to the direction of the relative motion trend of the object". The specific method is: firstly, select the object subject to static friction as the research object, Then, the object in contact with the research object is selected as the reference object, and the velocity direction of the research object relative to the reference object, that is, the direction of relative motion trend, is judged by assuming that the contact surface is smooth. Then, the direction of static friction is opposite to the direction of relative motion trend

There are West African Monetary Union, Central African Monetary Union and African Development Fund. Among them, West African Monetary Union is a typical form of African Monetary Integration

the African Franc is commonly used, which can be divided into the West African Franc and the Central African Franc. It is called the West African Franc in the West African Economic and Monetary Union (member countries: Beninese, burkinje, Cote d'Ivoire, guinea pig, Mali, Niger, Senegal and Togo), and in the Central African Economic and Monetary Community (member countries: Cameroon, Central Africa, Congo (Brazzaville), Gabon and Gabon) Equatorial Guinea and Chad) are known as the Central African Franc

the exchange rates of the West African Franc and the Central African Franc are equal, 100 RMB = 8542.3100 CFA francs

the origin of the African Franc

the African Franc was born on December 26, 1945. It is a currency designed by France for its former colonial countries. The French abbreviation of CFFA is "FCFA", which originally means "French colony franc of Africa"

broadly speaking, the CFA also includes the 15th country, Comoros, whose currency is called Comoros franc. In 2016, the exchange rate was 1 euro = 495 Comorian francs, which is about 75% of the value of the African Franc

at the beginning of the use of CFA, the French colonies in West Africa and Central Africa that used CFA had not been independent. After the independence of African countries, France signed currency cooperation agreements with these countries, which linked the French franc to the African Franc to ensure the convertibility of the African Franc and guaranteed by the French Treasury

5.

There are dozens of countries in Africa, and their currencies are not completely unified

In fact, despite the prevalence of the US dollar, almost every African country has its own official currency, and its monetary unit is not the same, and it is closely related to its colonial powers, the most prominent of which is the African Franc

African Franc (FCFA) refers to "colonies Fran & amp# 231; aises d’Afrique” After African countries became independent one after another, there appeared two Franc zones, and the definition of Franc in each zone was also different

in WAEMU, FCFA is called "African Financial Community Franc" é financi è Re d'Afrique for short. There are eight countries that use the West African Franc, namely, Burkinabe, Benin, Togo, guinea pigs, Cote d'Ivoire, Mali, Niger and Senegal

Beninese CFA franc

and "Central African Financial Cooperation Franc" coop é ration financi è "Re en Afrique central" is a kind of currency issued by the banks of the countries of the Central African Economic Community, which is called Central African CFA franc for short. There are six countries using the CFA franc, including Equatorial Guinea, the Republic of Congo, Gabon, Cameroon, Chad and the Central African Republic

it should be noted that although the Central African Franc and the West African Franc are equivalent, they do not circulate with each other

Burundi Franc

, in addition, some countries which once belonged to the French and Belgian colonies, their official currencies were also called francs, including Guinea, Djibouti, Rwanda, Burundi and Comoros, of which the Comoros also belonged to the African Franc area. p>

the original legal tender of Madagascar is Malagasy franc, which has been transferred to Malagasy ariary since January 1, 2005

In the past, most British colonies also used the same monetary unit, such as Kenya, Somalia, Uganda and Tanzania

The name of the Dinar comes from a kind of silver coin called denarius in the Roman Empire. The African countries with Dinar as currency unit are Libya, Tunisia and Algeria. The word rupee means "silver coin", which is used in Mauritius and Seychelles

The monetary unit of Zimbabwe and Liberia is the same as that of China. The monetary unit of Egypt and Sudan is the pound

Mauritian rupee

in addition, the names of monetary units in some African countries are strange to read. They come from other elements such as their own geography or culture

6. The exchange rate between RMB and African currency is about 1:990, and 100 yuan should be equal to 99000 African currency

7. Hello, there are more than 50 countries in Africa. The currency value of each country is different. You don't think dozens of countries in Africa use the same currency, do you

8. There are dozens of countries in Africa. You can't answer such a general question
Africa is not the same as Europe. The Union has a Euro! But generally speaking, the currencies of African countries are very low, not worth a few dollars
the currency value of each country is different, so there is no specific exchange standard
in some African countries, one RMB can be converted into dozens to 100 currencies. If it is Zimbabwe's currency, it can be converted into millions

9. The African Franc area is composed of 15 African countries, most of which were French colonies before independence. At first, the French franc was used as the general currency. Since 1945, the French colonial franc, which maintained a fixed parity with the French franc, was used as the general currency, referred to as the African Franc or the African Franc. In the early days, the French government was responsible for the distribution of the African Franc. In 1955, the distribution right was transferred to the local governments of the French West African colonies and the French Equatorial African colonies. In the early 1960s, after the independence of the French West African colonies and the French Equatorial African colonies, they continued to use the African Franc as legal tender. Among them, the former French West African colonies formed the West African Monetary Union. The full name of the African Franc used by the member states of the union is the African Financial Community Franc, which is issued by the Central Bank of West African countries under the union; The former French Equatorial African countries formed the Central African Customs and economic union. The full name of the franc used by the member countries of the union is the franc for China Africa financial cooperation, which is issued by the Bank of China Africa countries under the union. In addition to the different issuing banks, the exchange rates of the two currencies are fixed and freely convertible. The French Treasury guarantees the value and exchange rate of the franc on the condition that the countries in the African Franc Zone deposit 65% of their foreign exchange earnings into the French Treasury. After decades of operation, the African Franc has graally become a relatively stable currency with high credibility, and even the people of African countries outside the CFA are willing to hold it. Obviously, the countries in the CFA, which have made slow progress in the field of economic and trade cooperation as a whole, have taken the lead in the field of currency cooperation in the world, although this kind of advanced cooperation is e to the intervention and participation of developed countries. In addition to the CFA, South Africa, Lesotho, Swaziland and Namibia in southern Africa have actually formed some kind of monetary union. The four countries first used the South African currency Rand. Later, in order to show their economic independence, Lai, Sri Lanka and Na all issued their own currencies. However, their currency value and exchange rate have been floating according to the equivalent value of Rand and exchange rate, and the funds of the four countries can basically flow freely. The current west African Franc used by eight countries of the West African Economic and Monetary Union and the Central African Franc used by six countries of the Central African Economic and Monetary Community; Both regions belong to the former CFA franc zone (15 countries).
