Haitian CreoleHaitian Creole (ˈheɪʃən_ˈkriːoʊl; kreyòl ayisyen, kɣejɔl ajisjɛ̃; créole haïtien, kʁe.ɔl ai.sjɛ̃), commonly referred to as simply Creole, or Kreyòl in the Creole language, is a French-based creole language spoken by 10–12 million people worldwide, and is one of the two official languages of Haiti (the other being French), where it is the native language of the vast majority of the population. Northern, Central, and Southern dialects are the three main dialects of Haitian Creole.
MartiniqueMartinique (ˌmɑːrtᵻˈniːk , maʁtinik; Matinik or Matnik; Kalinago: Madinina or Madiana) is an island which is a single territorial collectivity of the French Republic. It is also part of the European Union as an Outermost Region within the Special territories of members of the European Economic Area, but is not part of the Schengen Area and the European Union Customs Union. As part of the French (Antilles) West Indies, Martinique is located in the Lesser Antilles of the West Indies in the eastern Caribbean Sea.
Electric chargeElectric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative (commonly carried by protons and electrons respectively, by convention). Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
Charge densityIn electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m−3), at any point in a volume. Surface charge density (σ) is the quantity of charge per unit area, measured in coulombs per square meter (C⋅m−2), at any point on a surface charge distribution on a two dimensional surface.
