The watt is a unit of power. In the International System of Units it is defined as a derived unit of 1 joule per second, is used to quantify the rate of energy transfer. In SI base units, the watt is described as kg m2 s-3, which can be demonstrated to be coherent by dimensional analysis; the watt is named after an 18th century Scottish inventor. When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is done is one watt. 1 W = 1 J s = 1 N ⋅ m s = 1 k g ⋅ m 2 s 3 In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere flows across an electrical potential difference of one volt, meaning the watt is equivalent to the volt-ampere. 1 W = 1 V ⋅ 1 A Two additional unit conversions for watt can be found using the above equation and Ohm's law. 1 W = 1 V 2 Ω = 1 A 2 ⋅ Ω. A person having a mass of 100 kilograms who climbs a three-meter-high ladder in five seconds is doing work at a rate of about 600 watts.
Mass times acceleration due to gravity times height divided by the time it takes to lift the object to the given height gives the rate of doing work or power. A laborer over the course of an eight-hour day can sustain an average output of about 75 watts; the watt is named after the Scottish inventor James Watt. This unit was proposed by C. William Siemens in August 1882 in his President's Address to the Fifty-Second Congress of the British Association for the Advancement of Science. Noting that units in the practical system of units were named after leading physicists, Siemens proposed that Watt might be an appropriate name for a unit of power. Siemens defined the unit within the then-existing system of practical units as "the power conveyed by a current of an Ampère through the difference of potential of a Volt."In October 1908, at the International Conference on Electric Units and Standards in London, so-called "international" definitions were established for practical electrical units. Siemens' definition was adopted as the "international" watt.
The watt was defined as equal to 107 units of power in the "practical system" of units. The "international units" were dominant from 1909 until 1948. After the 9th General Conference on Weights and Measures in 1948, the "international" watt was redefined from practical units to absolute units. Concretely, this meant that 1 watt was now defined as the quantity of energy transferred in a unit of time, namely 1 J/s. In this new definition, 1 "absolute" watt = 1.00019 "international" watts. Texts written before 1948 are to be using the "international" watt, which implies caution when comparing numerical values from this period with the post-1948 watt. In 1960 the 11th General Conference on Weights and Measures adopted the "absolute" watt into the International System of Units as the unit of power. For additional examples of magnitude for multiples and submultiples of the watt, see Orders of magnitude The attowatt is equal to one quintillionth of a watt; the sound intensity in water corresponding to the international standard reference sound pressure of 1 μPa is 0.65 aW/m2.
The femtowatt is equal to one quadrillionth of a watt. Technologically important powers that are measured in femtowatts are found in references to radio and radar receivers. For example, meaningful FM tuner performance figures for sensitivity and signal-to-noise require that the RF energy applied to the antenna input be specified; these input levels are stated in dBf. This is 0.5477 microvolt across a 300-ohm load. The picowatt, not to be confused with the much larger petawatt, is equal to one trillionth of a watt. Technologically important powers that are measured in picowatts are used in reference to radio and radar receivers, acoustics and in the science of radio astronomy. One picowatt is the international standard reference value of sound power when this quantity is expressed as a level in decibels; the nanowatt is equal to one billionth of a watt. Important powers that are measured in nanowatts are typically used in reference to radio and radar receivers; the microwatt is equal to one millionth of a watt.
Important powers that are measured in microwatts are stated in medical instrumentation systems such as the EEG and the ECG, in a wide variety of scientific and engineering instruments and in reference to radio and radar receivers. Compact solar cells for
Henrik Galeen was an Austrian-born actor and film director considered an influential figure in the development of German Expressionist cinema during the silent era. Considerable mystery exists about Galeen's early life, for many years it was uncertain where he was born. Galeen came from a Jewish family in Lemberg, part of the Austrian Empire, he moved from Austria to Germany before the First World War, became assistant to the leading theatre figure Max Reinhardt. Galeen subsequently became an actor in Berlin and touring other German-speaking cities. Galeen first became involved in film in 1913 when he worked on the screenplays for several uncredited films. In 1914 he wrote and acted in The Golem the first of several depictions of the mythical figure The Golem. Following the First World War, he went to work for a branch of the major German studio UFA, he worked as a screenwriter on films such as Ruth's Two Waxworks. In 1922 he was engaged to write a version of Dracula, but wrongly believing it to be in copyright, he changed the name to Nosferatu.
The film has come to be regarded as a classic of German expressionist cinema and along with two of his films, The Student of Prague and Alraune, serves as the basis for Galeen's high reputation. He worked on a number of less-remembered films including a series of thrillers starring Harry Piel. From 1928 to 1931 he lived in Britain, where he directed a feature film After the Verdict, the first film to be shot at Wimbledon, he worked on a number of short films. He directed a final film there The House of Dora Green. Following the Nazi Party's rise to power in 1933, Galeen went into exile in Sweden before moving on to the United Kingdom and to the United States. Isenberg, Noah William.

This is a list of the mayors and lord mayors of the City of Perth, a local government area of Western Australia. The office of head of the municipality of Perth is defined over three distinct periods: From 1829 to 1838 — controlled by the Governor of Western Australia From 1838 to 1858 — controlled by the Perth Town Trust From 1858 to present — controlled by the Perth City Council renamed City of Perth On 15 June 1837, an Act was proclaimed to..provide for the management of roads and other internal communications within the settlement of Western Australia. The management and control was vested in a body of trustees consisting of the Justices of the Peace resident in the town; the act was repealed in September 1842 and authority was conferred on elected representatives. The first elected Chairman and committee took office on 8 February 1842 and comprised: Walter Boyd Andrews George Leake, James Purkis, Peter Broun, W. H. Drake, Richard Jones James Purkis was appointed treasurerOn 23 February 1856, Perth was constituted a city upon the foundation of the Bishopric of Perth through the consecration of the first Anglican Bishop of Perth, Matthew Blagden Hale.
From 1858 to 1880, the President of the Council was styled "Chairman", from 1880 until 1929, the Chairman was termed the "Mayor" and from 1929 the mayor was elevated to the title of "Lord Mayor". W.
