Relationship to energy in physics
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.
"Energy" contains samples from Eazy-Duz-It performed by Eazy-E and Ridin Spiners performed by Three 6 Mafia. Energy was produced by Boi-1da and OB O'Brien. According to WhoSampled the song samples the score of an episode of The O.C..
Critical reception
"Energy" received acclaim from music critics with many calling it the best song of the album. Ryan Dombal of Pitchfork gave the song a positive review and named it "Best New Track", stating "The song isn't aimed to any rappers or pop stars, not Kendrick Lamar, Big Sean or Tyga, but the song lines are dangerous."

Release
The video of "Energy" was released on Apple Music and users with iTunes and registered Apple Music account can watch this video.
"Energy" is a song performed by American singer Melissa Manchester, from her 1985 album Mathematics.
Details
The song was arranged by veteran songwriter Greg Mathieson and was released as the second single from the album, following the underperformance of the lead single "Mathematics", MCA hoped to reverse the album's fortune by releasing this Hi-NRG track with an aim for the club market.
Melissa Manchester filmed a videoclip to promote the song, which sees the singer and her band in a sort of industrial-setting stage performing the song.
The single was released on 7" and 12" formats featuring remixes, but it failed to chart either on the Billboard Hot 100 or the dance charts, and failed to chart elsewhere. The b-side to the single was a non-album song, called "So Full Of Yourself", which was co-written by Manchester and Tom Snow and used as the b-side to all 3 singles off the album.
The following tables present the ranks of the Indian army. These ranks generally correspond with those of Western militaries, and in particular reflect those of the British and Commonwealth armies. Traditional names for ranks are still used, as well as Western names.
Field marshal
India has a field marshal rank, but it is mostly ceremonial. There are no field marshals in the army organizational structure at present and it has been conferred on only two officers in the past, the late Field Marshal Sam Manekshaw and the late Field Marshal K M Cariappa.
Field marshals hold their rank for life, and are considered to be serving officers until their death. Unlike other officers, they do not draw a pension. A field marshal gets the full pay of a general equal to the Chief of the Army Staff. He wears full uniform on all official occasions and runs an office in army headquarters. He also has a dedicated secretariat of his own.
The manga series concluded in the 32nd issue of Shōnen Sunday for 2010, while the 78th and final volume of the manga series was released in the middle of December 2010 together with a special original video animation (OVA).
The series has been adapted into an anime series produced by NHK and Studio Hibari titled Major(メジャー,Mejā) (using katakana instead of the manga's English characters). The first episode aired on November 13, 2004. The series ran for six seasons and the final episode originally aired on September 25, 2010. An animated film telling the story between the first and second seasons of the anime was released on December 13, 2008. Two OVAs were released on December 16, 2011, and January 18, 2012. They deal with The World Series chapter, which was skipped in the TV series.
Major is a rank of the Canadian Forces. The rank insignia of a major in the Royal Canadian Air Force is two half-inch stripes with a quarter-inch stripe between. The rank insignia in the Canadian Army is a crown. Majors fill the positions of company/squadron/battery commanders, or deputy commanders of a battalion/regiment; in the Air Force they are typically squadron second-in-command, or commander of a detached helicopter flight embarked onboard Canadian naval vessels. The naval equivalent rank for major is lieutenant-commander.
