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".

Rise (Flobots song)

"Rise" is the second single released by the alternative hip hop group Flobots from Denver, Colorado. It was released from Flobots' album Fight with Tools.

Music video

The Flobots filmed a music video for this song on July 6, 2008, at the Gothic theater In Denver, Colorado. The video shows a rock concert intermixed with scenes of pro-American posters and people working to make the world a better place, such as planting trees and committing random acts of kindness. The video features almost everyone in some form of American Flag bandanna, much like the cover for Flobot's album "Fight with Tools." In the video, multiple references are made to the website americawillbe.org, a pro-peace website dedicated to the visions of what people want USA to be.

Chart performance

On September 13, 2008, "Rise" charted on the Billboard Hot Modern Rock Tracks at number 36. So far, the song has peaked at number 33.

Rise: Blood Hunter

Rise: Blood Hunter is a 2007 neo-noir action-horror film written and directed by Sebastian Gutierrez. The film stars Lucy Liu and Michael Chiklis; a supernatural thriller about a reporter (Liu) who wakes up in a morgue to discover she is now a vampire. She vows revenge against the vampire cult responsible for her situation and hunts them down one by one. Chiklis plays "Rawlins," a haunted police detective whose daughter is victimized by the same group and seeks answers for her gruesome death.

Plot

Reporter Sadie Blake has just published a notable article featuring a secret Gothic party scene. The very night following the publication, one of Sadie's sources, Tricia Rawlins, is invited by her friend Kaitlyn to an isolated house in which such a party is to take place. Tricia is reluctant to enter with the curfew set by her strict father, so Kaitlyn goes alone. When she does not return, Tricia becomes worried and enters the house as well. To her horror, she finds Kaitlyn in the basement with two vampires hanging onto her and drinking her blood. She tries to hide, but the vampires find her quickly. The next day, Sadie learns of the girl's death and decides to investigate the matter. She soon attracts the interest of the vampire cult, who kidnap her and bring her in for questioning. Following that, she is raped and murdered by the vampires.
