The joule (/ dʒ uː l / JOOL, or / dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). [1] In terms of SI base units, one joule corresponds to one kilogram-square metre per square second (1 J = 1 kg⋅m 2 ⋅s −2).
In the Metric system, J is the symbol for the joule, the SI derived unit for energy. In some areas of physics, electrical engineering and related fields, j is the symbol for the imaginary unit (the square root of −1) (in other fields, the letter i is used, but this would be ambiguous as it is also the symbol for current).
The symbol in the International Phonetic Alphabet that represents this sound is j . The equivalent X-SAMPA symbol is j , and in the Americanist phonetic notation it is y . Because the English name of the letter J , jay , starts with [dʒ] ( voiced postalveolar affricate ), the approximant is sometimes instead called yod [ citation needed ] , as ...
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.
As of Unicode version 16.0, there are 155,063 characters with code points, covering 168 modern and historical scripts, as well as multiple symbol sets.This article includes the 1,062 characters in the Multilingual European Character Set 2 subset, and some additional related characters.
The equivalent X-SAMPA symbol is J. The IPA symbol ɲ is visually similar to ɳ , the symbol for the retroflex nasal, which has a rightward-pointing hook extending from the bottom of the right stem, and to ŋ , the symbol for the velar nasal, which has a leftward-pointing hook extending from the bottom of the right stem.
The symbol in the International Phonetic Alphabet (IPA) that represents this sound is ʝ (crossed-tail j), and the equivalent X-SAMPA symbol is j\. It is the non-sibilant equivalent of the voiced alveolo-palatal sibilant. In broad transcription, the symbol for the palatal approximant, j , may be used for the sake of simplicity.
In the International Phonetic Alphabet (IPA), palatalized consonants are marked by the modifier letter ʲ , a superscript version of the symbol for the palatal approximant j . For instance, tʲ represents the palatalized form of the voiceless alveolar stop [t].
