Liberia ⁱ/laɪˈbɪəriə/, officially the Republic of Liberia, is a country on the West African coast. Liberia means "Land of the Free" in Latin. It is bordered by Sierra Leone to its west, Guinea to its north and Ivory Coast to its east. It covers an area of 111,369 square kilometres (43,000 sq mi) and is home to 4,503,000 people.English is the official language and over 20 indigenous languages are spoken, representing the numerous tribes who make up more than 95% of the population.

Forests on the coastline are composed mostly of salt-tolerant mangrove trees, while the more sparsely populated inland has forests opening onto a plateau of drier grasslands. The climate is equatorial, with significant rainfall during the May–October rainy season and harsh harmattan winds the remainder of the year. Liberia possesses about forty percent of the remaining Upper Guinean rainforest. It was an important producer of rubber in the early 20th century.

West Africa

West Africa, also called Western Africa and the West of Africa, is the westernmost subcontinent of Africa. West Africa has been defined as including the 18 countries Benin, Burkina Faso, the island of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, Sao Tome and Principe and Togo.

History

The history of West Africa can be divided into five major periods: first, its prehistory, in which the first human settlers arrived, developed agriculture, and made contact with peoples to the north; the second, the Iron Age empires that consolidated both intra-African, and extra-African trade, and developed centralized states; third, Major polities flourished, which would undergo an extensive history of contact with non-Africans; fourth, the colonial period, in which Great Britain and France controlled nearly the whole of the region; fifth, the post-independence era, in which the current nations were formed.

Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.

Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

Money Talks

Money Talks is a 1997 American action comedy film directed by Brett Ratner, starring Chris Tucker and Charlie Sheen. This film is the first of four collaborations between Brett Ratner and Chris Tucker, with the other three being the Rush Hour Trilogy.

Plot

Franklin Maurice Hatchett (Chris Tucker) is a small-time car wash hustler and ticket scalper who owes money to a local gang leader named Carmine (Damian Chapa). He gets dimed out to the police by an investigating news reporter named James Russell (Charlie Sheen) after unintentionally thwarting Russell's attempts to have him confess his crimes on camera, and is taken to jail. When placed on a prison transport unit, he is handcuffed to a French criminal named Raymond Villard. The transport unit is attacked on a bridge, with mercenaries killing all the police officers and prisoners except for Franklin and Villard; the mercenaries are Villard's men, but since he is handcuffed to Hatchett he decides to bring him for the moment, and they escape on a helicopter with another French criminal named Dubray. While on the helicopter, Hatchett overhears the two discussing the location of a cache of stolen diamonds. Hatchett then jumps out of the helicopter after realizing that Villard and Dubray plan to kill him. While eating at a local diner, Franklin and Villard's mugshots are shown on the news as the two men who killed several police officers. Two other officers in the diner then recognize Franklin, and chase him into the street. He is able to elude them, and decides to call Russell after seeing his face on an advertisement.

Power station

A power station (also referred to as a generating station, power plant, powerhouse, or generating plant) is an industrial facility for the generation of electric power. Most power stations contain one or more generators, a rotating machine that converts mechanical power into electrical power. The relative motion between a magnetic field and a conductor creates an electrical current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Others use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric.

History

The world's first power station was designed and built by Lord Armstrong at Cragside, England in 1868. Water from one of the lakes was used to power Siemens dynamos. The electricity supplied power to lights, heating, produced hot water, ran an elevator as well as labor-saving devices and farm buildings.
