lightning and static essays

lightning and static essays Lightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the sun's surface about 50,000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions in the ground. Static electricity is negatively and positively charged atoms. A static charge on the other hand is a individual atom with a negative or positive charge. There are three types of charges negative positive and neutral. Negative and positive ions attract. But two negatives repel each other, just like two positives will. Neutrally charged ions can attract to both negative and positive ions, because they have and balanced charge of negative and positive ions, this means it has the same amount of negative and positive ions. This is where the following rule is true "opposites attract, and likes repel." Static electricity is generated when two different objects are rubbed together and some electrons are stolen from one object and then start to collect on the surface of the other object. The object that loses electrons becomes positively charged, because electrons are negatively charged and there is an absence of electrons and too many protons. Now because opposites attract and like repel the reason hair stands up when you rub something on it can be explained. When something is rubbed in a dry place, the thing takes electrons from your hair, leaving your hair with a positive charge it stands up as far away as possible from the other positively charged hairs. There reason there is little static electricity in areas with a high humidity, like the Virgin Islands, is because the humidity in the air is a conductor of electricity, so it helps trancfer the free e...

African-American Vernacular English (AAVE)

African-American Vernacular English (AAVE) African-American Vernacular English (AAVE) is a  variety of American English spoken by many African Americans. It has been called by many other names that are sometimes offensive, including African American English, black English, black English vernacular, ebonics, negro dialect, nonstandard negro English, black talk, blaccent, or blackcent. AAVE originated in the slave plantations of the American South, and it shares a number of phonological and grammatical features with Southern dialects of American English. Many African Americans are bi-dialectal in AAVE and Standard American English. Several concepts are related to this complex topic, including: African-American RhetoricBe  DeletionCode SwitchingDialect PrejudiceDiglossiaDouble CopulaDozensDummy  ItEthnic DialectInvariant  BeMetathesisNegative ConcordSerial VerbsSignifyingSubject-Auxiliary Inversion (SAI)West African Pidgin EnglishZero Copula and Zero Possessive Examples and Observations In line with evolving trends within the larger community, linguists use African American English instead of Black English (or even older terms like Non-Standard Negro English) for the English of African Americans, a continuum of varieties ranging from the most mainstream or standard speech (like Bryant Gumbels, virtually indistinguishable from the formal speech of white and other Americans), to the most vernacular or non-mainstream variety. It was to focus on this latter variety that Labov (1972) first started referring to it as Black English vernacular. African American Vernacular English is simply the most recent variety of that term, the one most widely used among linguists...The term Ebonics, which was first coined in 1973 by a group of Black scholars...from ebony (black) and phonics (sound, the study of sound) (R. Williams, 1975)...is regarded by many if not most linguists as very similar if not identical to AAVE in terms of the features and varieties it designates. (Rickford, African American Vernacular English) [C]ontributing to the evolution of American English was the migration of blacks from the South after the Civil War to urban areas of the north. They took their Southern speech patterns with them, including all of the linguistic forms that had been incorporated into the grammatical structure of speech among slaves. Unlike most white immigrants to urban centers, who eventually adopted local dialects, blacks generally remained isolated in impoverished ghettos and as a result, retained their dialect. This physical isolation contributed to linguistic isolation and the maintenance of African American vernacular English (AAVE). The retention of unique linguistic forms, racism, and educational apartheid have since led to numerous misconceptions of this dialect. (Baugh, Out of the Mouths of Slaves: African American Language and Educational Malpractice) The Two Components of AAVE It is proposed that AAVE consists of two distinct components: the General English [GE] component, which is similar to the grammar of OAD [Other American Dialects], and the African-American [AA] component. These two components are not tightly integrated with each other, but follow internal patterns of strict co-occurrence...The AA component is not a complete grammar, but a subset of grammatical and lexical forms that are used in combination with much but not all of the grammatical inventory of GE. (Labov, Coexistent Systems in African-American English) Origin of AAVE On one level, the origin of African American English in the USA will always be a matter of speculation. Written records are sporadic and incomplete, and open to interpretation; demographic information about language use is also selective and largely anecdotal. Furthermore, great variation was exhibited in the speech of Africans when they were first brought to the New World and to colonial America, as indicated in references to black speech in slave advertisements and court records (Brasch, 1981). It is also indisputable that English-lexifier Creole languages developed and continue to flourish in the African diaspora - from coastal West Africa to coastal North America - and that the middle passage for some Africans brought to colonial America included exposure to these creoles (Kay and Cary, 1995; Rickford, 1997, 1999; Winford, 1997). Beyond these acknowledgments, however, the origin and status of early African American speech has been and continues to be vigorously disputed.
