Work (electrical)

Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical' work is equivalent to that of 'mechanical' work:

where

The electrical work per unit of charge, when moving a negligible test charge between two points, is defined as the voltage between those points.

Overview

Qualitative overview

Particles that are free to move, if positively charged, normally tend towards regions of lower voltage (net negative charge), while if negatively charged they tend to shift towards regions of higher voltage (net positive charge).

However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force, work equal to that electric field would do in moving that positive charge the same distance in the opposite direction. Similarly, it requires positive external work to transfer a negatively charged particle from a region of higher voltage to a region of lower voltage.

The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage (electric potential) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero. The same holds for electric fields.

Work of art

A work of art, artwork, art piece, piece of art or art object is an aesthetic physical item or artistic creation. Apart from "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:

Used more broadly, the term is less commonly applied to:

Work (Rihanna song)

"Work" is a song recorded by Barbadian singer Rihanna for her eighth studio album, Anti (2016). The song features a verse by Canadian rapper Drake. The artists co-wrote the single with PartyNextDoor, Allen Ritter, Rupert Thomas, R. Stephenson, Monte Moir, and Boi-1da; the latter is also the producer.

Upon its release, "Work" received mixed reviews from music critics. The song debuted at number nine and has so far peaked at number seven on the Billboard Hot 100, becoming Rihanna's 27th and Drake's 15th top ten entry on the chart. It has also peaked within the top ten of the charts in Australia, Canada, France, Hungary, Spain, and the United Kingdom.

Writing and development

"Work" was written by the artists, PartyNextDoor, Allen Ritter, Rupert "Sevn" Thomas, Monte Moir, R. Stephenson, and Boi-1da; the latter is also the producer. In the summer of 2015, Thomas, Ritter, Boi-1da and Martin Mason among others, stayed at Drake house in Los Angeles for a mid-week period. Thomas described the time spent at the home as a "beat factory, everyone was sitting there working and collaborating with each other." Thomas created a beat which was dancehall-influenced; he later played it for Boi-1da to which he positively responded, "We’re both Jamaican-Canadian. It was just something in our DNA, so it woke him up, and we started remembering all these old dancehall songs from the '90s." Boi-1da came with up idea for sampling an "old school dancehall rhythm" and after that the chords were made with Ritter and past it, "everything went organically".

HIDDEN ERROR: Usage of "death cause" is not recognizedHIDDEN ERROR: Usage of "education" is not recognized

Carlos (February 20, 1943 in Paris – January 17, 2008 in Clichy, Hauts-de-Seine), born Yvan-Chrysostome Dolto, was a French singer, entertainer and actor. He is sometimes called Jean-Christophe Doltovitch.

Biography

He was the son of the psychoanalyst Françoise Dolto and the physiotherapist Boris Dolto. He also obtained a diploma in 1961 at l’École française d'orthopédie et de masso-kinésithérapie, headed by his father.

At the age of 14 he met Johnny Hallyday, who befriended him. He was renamed Carlos in 1958, in homage to the percussionist Carlos "Patato" Valdes. He then became Hallyday's artistic assistant. From 1962 to 1972, he was Sylvie Vartan's artistic assistant, and it was he and Vartan who discovered Mike Brant, whom they brought to France in 1969.

Carlos was heavily overweight and cultivated a jovial countenance, and adopted a look similar to the singer Antoine, with leis and Hawaiian shirts. In 1980, he became a spokesman for the Oasis brand fruit drink, with his song "Rosalie" (a cover of George Plonquitte singer of Typical Combo, a group Guadeloupean) being used in their television advertisements.
