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".

Men...

Men… (German: Männer…) is a 1985 West German comedy film directed by Doris Dörrie. It was chosen as West Germany's official submission to the 59th Academy Awards for Best Foreign Language Film, but did not manage to receive a nomination.

Man (Middle-earth)

In J. R. R. Tolkien's Middle-earth books, such as The Hobbit and The Lord of the Rings, the terms Man and Men refer to humankind – in contrast to Elves, Dwarves, Orcs and other humanoid races – and does not denote gender.

The Elves call the race of Men Atani in Quenya, literally meaning "Second People" (the Elves being the First), but also Hildor (Followers), Apanónar (After-born), and Fírimar or Firyar (Mortals). Less charitably they were called Engwar (The Sickly), owing to their susceptibility to disease and old age, and their generally unlovely appearance in the Elves' eyes. The name Atani becomes Edain in Sindarin, but this term is later applied only to those tribes of Men who are friendly to the Elves. Other names appear in Sindarin as Aphadrim, Eboennin, and Firebrim or Firiath.

Origins

The race of Men is the second race of beings created by the One God, Ilúvatar. Because they awoke at the start of the Years of the Sun, while the Elves awoke at the start of the First Age during the Years of the Trees, they are called the Afterborn by the Elves.

Men (1918 film)

Men was a 1918 American silent societal drama film directed by Perry N. Vekroff based upon a play by Harry Sophus Sheldon. It starred Anna Lehr, Charlotte Walker, and Robert Cain. It is considered to be a lost film.

Plot

As described in a film magazine, Laura Burton (Lehr) refuses the love of an honest artist to accept the flattering attentions of Roger Hamilton (Cain), a society pet. In due time, however, she finds that she has been betrayed and returns to her mother (Walker). She reads of Hamilton's engagement to Alice Fairbanks (McCoy) who, in reality, is her sister adopted by the Fairbanks in childhood. Laura and her mother arrive in time to prevent the completion of the ceremony. Hamilton is denounced, Alice is free to marry the man she loves, and the young artist returns to claim Laura.
