Lenz's law is a common way to understand how electromagnetic circuits obey Newton's third law and the conservation of energy.&lt;ref name="Electromagnetics explained: a handbook for wireless/RF, EMC, and high-speed electronics"&gt;Schmitt, Ron. "Electromagnetics explained". 2002. Retrieved 16 July 2010.&lt;/ref&gt; Lenz's law is named after Emil Lenz, and it says: An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the change in original magnetic flux. Lenz's law is shown with the negative sign in Faraday's law of induction: formula_1, which indicates that the induced emf (ℰ) and the change in magnetic flux (∂Φ"B") have opposite signs. The induced emf and the resulting induced current are counterclockwise when B' is directed out from the page and the area of the circuit is decreasing. The flux through this circuit is decreasing in the outward direction. Now the induced current I produces its own magnetic field, and we may use the right-hand grip rule to compute the direction of this field. The result is that the magnetic field due to the induced current is also directed outward within the circuit. It is as though nature, through this induced field, tried to compensate for the reduction in the flux due to the applied field B. This turns out experimentally to be a general rule, so that we may say that"The direction of the induced emf is always such as to result in opposition to the change producing it."That is "Lenz's law". As another example of the application of Lenz's law, consider a coil of wire to which a battery is suddenly connected. Suppose that the battery starts a current flowing clockwise, as viewed by the observer. This current will give rise to a magnetic field whose lines will thread the coil and circle back outside it. As the current due to the battery builds up, there is a changing magnetic flux through the coil and this must result in an induced emf in the coil. What is the direction of this induced emf? Lenz's law tells us immediately that it

ABC Kids was an American television programming block produced by ABC Productions. It was distributed by Buena Vista Television Group, a division of Disney Media Networks, which aired on ABC. It broadcasted several different children’s television series. These series were all owned by Disney Media Networks, the owner of ABC Entertainment Group. Most of them were also shown on Buena Vista Television Group’s own network Disney Channel. Family Guy: Season 1-22 Episode 1-5 American Dad!: Season 1-20 Episode 1-17 History. On September 13, 1997, "Disney's One Saturday Morning" started out as a two-hour block on the "ABC Saturday Morning" lineup, and aired some of the former's shows. In 1999, it was extended to 5 hours. On September 6, 1999, a spin-off, "Disney's One Too", aired on UPN and in syndication every weekday in the morning or afternoon and Sunday morning. "One Saturday Morning" last aired on September 7, 2002. On September 14, 2002, Disney renamed "One Saturday Morning" to ABC Kids. The block originally had new programs, but by the end, all of ABC Kids programs became repeats of Disney Channel originals. "Power Rangers" was previously aired on Fox Kids until halfway through the "Wild Force" season, when "Power Rangers" moved to ABC Kids for the 2002 Fall season due to the Fox Family Channel/Saban Entertainment purchase by Disney in 2001. Starting with the episode "Unfinished Business", the remainder of the "Wild Force" season premiered on ABC Kids. During its time on both Fox Kids and ABC Kids the entire "Wild Force" season also ran again later on ABC Family (in part both before the introduction of and during the ABC Family Action Block). The following "Ninja Storm" season also premiered on ABC Kids and then ran again later on the ABC Family Action Block. The "Dino Thunder", "S.P.D.", "Mystic Force", "Operation Overdrive" and "Jungle Fury" seasons were all shown on Jetix and then ran again on ABC Kids. The "RPM
A circuit containing resistance (R), inductance (L), and capacitance (C) is called an RLC circuit. A simple circuit only has one RLC series. With a resistance "R" present, the total electromagnetic energy "U" of the circuit (the sum of the electric energy and magnetic energy) is no longer constant. Instead, it decreases with time as energy is transferred to thermal energy in the resistance. Because of this loss of energy, the oscillations of charge, current and potential difference continuously decrease in amplitude, and the oscillations are said to be damped.  They are damped in exactly the same way as those of the damped block-spring oscillator. To analyze the oscillations of this circuit, an equation can be written for the total electromagnetic energy formula_1 in the circuit at any instant. This is because the resistance does not store electromagnetic energy. formula_2  (Eq. 1) However, this total energy decreases as energy is transferred to thermal energy.  formula_3  (Eq. 2) where the minus sign indicates that formula_1 decreases. By differentiating Eq. 1 with respect to time and then substituting the result in Eq. 2, the following is obtained: formula_5 Substituting formula_6 for formula_7 and formula_8 for formula_9, the following is obtained: formula_10'  (RLC circuit)
Jackstones is a traditional Korean game. It is usually played by girls. The game is similar to the game Jacks. Jackstones is also a traditional game played in India Tamil Nadu by the name Anchakal it is also played in rural villages of Andhra Pradesh by the name of Achenagandlu or Achamgilla or Chintapikkala aata, using small stones or Tamarind seeds. Game play. The game is played with five stones. Each stone is about the size of an almond. Players can only use one hand to play the game. The game has five parts or "stages". In the first stage, the player throws the stones on the ground. They pick up one stone and throw it upward. Before the stone falls onto the ground, they need to pick up another stone from the ground and then catch the one that was thrown. This is done again until there are no stones on the ground. The second stage is the same with the first stage except that the player needs to pick up two stones at once before the stone which was thrown falls down. The third and the fourth stages are the same. In the fifth stage, players can get points. All of the stones are thrown upward. The player must catch as many of the stones as they can with the back of their hand. Then, the stones they caught are thown into the air again and the player must catch all of them. The player gets points for how many stones they catch. If they caught 3 stones, they get 3 points. If they caught 4 stones, they get four points. After that, the next player does the same. When all players have done this, the game is finished. The person (or the team) who has a higher point wins. Also there are several rules; If a player is out, the next person (or team) gets the turn.
Lorentz's law is a law discovered by the Dutch physicist Hendrik Antoon Lorentz. Lorentz's law defines force that acts on moving charged particles in an electromagnetic field. Force consists of magnetic force and electric force. F = qE (electric force) If the charge is positive, the direction of the electric force is equal to direction of electric field. F = qv*B (magnetic force) The direction of the magnetic force is given by the right hand rule. If charged particles move with velocity v in an electric field E and a magnetic field B F = qE + qv*B F : force (vector) q : charge (scalar) E : electric field (vector) v : velocity of particle (vector) B : magnetic field (vector) Using this law, J.J. Thomson measured mass-to-charge ratio.
Snell's Law of Refraction is the scientific law of the refraction of light or other waves. In optics, Snell's law is about the speed of light in different media. The law states that when light passes through different materials (for example from air to glass) the ratio of sines of the incidence (incoming) angle and the refraction (outgoing) angle does not change: formula_1 With each formula_2 as the angle measured from the normal of the boundary, formula_3 as the velocity of light in the respective medium (SI units are meters per second, or m/s). formula_4 is the refractive index of the medium. The index of refraction of a vacuum is 1 and the velocity of light in a vacuum is formula_5. When a wave passes the material where the index of refraction is n, the velocity of the wave becomes formula_6. Snell's law can be proved by Fermat's principle. Fermat's principle states that "light travels along the path which takes the least time". History. The idea has a long history. The problem had the attention of Hero of Alexandria, Ptolemy, Ibn Sahl, and Huygens. It was formulated by the Dutch astronomer and mathematician Willebrord Snel . Ibn Sahl actually discovered the law of refraction. In "Traité de la Lumiere", 1678, Huygens showed how Snell's law of sines could be explained by, or derived from, the wave nature of light.
The golden lion tamarin ("Leontopithecus rosalia"), also called the golden lion marmoset is a small, squirrel-sized monkey with a lion-like mane.  Tamarins live in small family groups. They are diurnal (most active during the day); at night, they rest in the cavity of a tree. The life span is about 15 years. They are in danger of extinction due to loss of habitat as their forest home is being cleared. These tamarins are arboreal (they live in trees). They live in coastal tropical rainforests in eastern Brazil of South America. Lion Tamarins take their name from their impressive manes—thick rings from Africa great cats lions.  The golden lion tamarin may be the most beautiful of the four lion tamarin species. Its golden hair frames a charismatic black face and covers its small body and tail.Despite their name, these rare primates have far more in common with their monkey relatives than any feline. Diet. The golden lion tamarin is an omnivore (eating both animals and plants); it eats insects, fruit, small snakes, lizards, snails, spiders, and vegetables. Tamarins use their claws to dig for insects in the bark of trees.
Mean Girls 2 is a 2011 American teen comedy television film directed by Melanie Mayron and written by Cliff Ruby, Elana Lesser, and Allison Schroeder. It is a sequel to the 2004 film "Mean Girls."
Piet Mondrian (7 March 1872 – 1 February 1944) was a Dutch modern artist of the De stijl group. His early paintings show abstract landscapes in post-impressionist and cubist style. As his career went on, he started to paint in a more abstract style.  Mondrian painted about 250 of these geometric abstracts, from 1917 to 1944. Mondrian called his style “neoplasticism”. Escaping in 1940 from a Europe at war, Mondrian spent the last four years of his life in New York City. His paintings of that time express exuberance at city life. In his final painting, "Broadway Boogie Woogie" (painted around 1942 or 1943), the checkerboard lines, previously black, are now painted blue, gray, red and yellow. The yellow was apparently inspired by New York’s Yellow cabs.
The 2004 Pacific hurricane season officially started May 15, 2004 in the eastern Pacific, and June 1, 2004 in the central Pacific, and lasted until November 30, 2004. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. Storms. Hurricane Darby. Tropical Depression Five-E formed south of Mexico on July 26. Later that day, it was upgraded to Tropical Storm Darby, and only four hours later, at 2 am (0900 UTC) on July 27, is upgraded to Hurricane Darby. It moved due west at this point, aiming directly for the big island of Hawaii. It reached Category 3 strength on July 29, the first major hurricane in the northeastern Pacific basin since 2002. However, long before it reached Hawaii, it lost strength and dissipated on the evening of July 31. Hurricane Howard. Tropical Depression Eleven_E formed from a tropical wave about 400 mi. southwest of Acapulco, Mexico and headed northwest, steadily strengthening as it did so. Howard peaked briefly as a Category 4 and then started to weaken. By the time Howard reached a point off the coast of the Baja peninsula, it was only a tropical storm. Howard weakened further, becoming a tropical depression on September 5 and degenerated into a remnant low later that day. The low hooked around and headed southwest. Howard dissipated on September 10 without making landfall. Hurricane Javier. Tropical Depression Thirteen-E formed out of an area of low pressure south-southeast of the Gulf of Tehuantepec on September 10. It slowly moved northwest, being designated Tropical Storm Javier on the morning of September 11. It was upgraded to a hurricane on the afternoon of September 12, and peaked at Category 4 strength on the Saffir-Simpson Hurricane Scale after rapidly strengthening on September 13.  Warnings began to be issued on September 15 for Baja California. While Javier peaked at Category 4, with windspeeds of 150 mph (240 km/h), it weakened dramatically before striking land south of San

In Major League Baseball, the American League Championship Series (ALCS), played in October, is a playoff round that decides the winner of the American League pennant. The winner of the series moves on to play the winner of the National League Championship Series in baseball's championship, the World Series. It is a "best-of-seven" series, meaning the first team to win four games  History. In 1969, MLB expanded the leagues to two divisions. As a result, the League Championship Series was implemented. Originally, it was a best-of-five series, meaning a team had to win three games to advance to the World Series. In 1985, the LCS was expanded to a best-of-seven format.  Since 1995, the two winners of the ALDS advance to the ALCS. List. Click the link on the far left for detailed information on that series. †"Denotes wild-card team (since 1995)."
In astronomy, stellar classification is a way of grouping stars by temperature. Star temperature can be measured by looking at its spectrum, the type of light that the star shines. Stars are also grouped into spectral types or classes by color. In general, a star's temperature determines its color, from red to blue-white. Spectral types are named with a letter. The seven main types are "M", "K", "G", "F", "A", "B" and "O". "M" stars are the coldest stars and "O" stars are the hottest.  Harvard spectral classification. The Harvard classification system is a one-dimensional classification scheme. Stars vary in surface temperature from about 2,000 to 40,000 kelvin. Physically, the classes indicate the temperature of the star's atmosphere and are normally listed from hottest to coldest, as is done in the following table:  Note: The conventional color description describe only the peak of the stellar spectrum. However, the actual apparent colors the eye sees are lighter than the conventional color descriptions.  The mass, radius, and luminosity listed for each class are appropriate only for stars on the main sequence portion of their lives and so are not appropriate for red giants and blue and red supergiants. The spectral classes O through M are subdivided by Arabic numerals (0–9). For example, A0 denotes the hottest stars in the A class and A9 denotes the coolest ones. The Sun is classified as G2. The Hertzsprung-Russell diagram is more often used in astronomy. It relates the absolute magnitude and the surface temperature. It is as important to astronomy as the periodic table is to chemistry. Luminosity classes. Luminosity classes also exist and stars can be assigned to one based on their spectrum. The conventional classes are called the Yerkes system. Our Sun, a yellow dwarf, is G2V. Red giants are K to M and have luminosity class III. Blue supergiants are O to A with II to Ia, while red supergiants are K to M with II to Ia. Conventional and apparent colors. The "conventional color" descriptions are traditional
Snow White and the Seven Dwarfs, also referred to as Snow White for short, is a 1937 American animated musical fantasy movie. It was made by Walt Disney Productions and released by RKO Radio Pictures. It is based on the German fairy tale "Snow White" by the Brothers Grimm. It is the first full-length cel animated movie and the first Walt Disney Animated movie. The story was adapted by storyboard artists Dorothy Ann Blank, Richard Creedon, Merrill De Maris, Otto Englander, Earl Hurd, Dick Rickard, Ted Sears and Webb Smith. David Hand was the supervising director, while William Cottrell, Wilfred Jackson, Larry Morey, Perce Pearce, and Ben Sharpsteen directed the movie's different sequences. "Snow White" was first shown at the Carthay Circle Theatre on December 21, 1937. It was released across the United States on February 4, 1938. With international earnings of $8 million when it first came out, the movie for a bit had the record of highest grossing sound movie anyone had made yet. The popularity of the movie has led to it being re-released theatrically many times, until its home video release in the 1990s. Adjusted for inflation, it is one of the top ten performers at the North American box office and the most successful animated movie that anyone has yet made. At the 11th Academy Awards, Walt Disney was awarded an honorary Oscar. The movie was nominated for Best Musical Score. It was added to the United States National Film Registry in 1989 and is ranked in the American Film Institute's list of the 100 greatest American films, who also named the movie as the greatest American animated movie of all time in 2008. Disney's take on the fairytale has had a huge cultural impact, resulting in popular theme park attractions, a video game, and a Broadway musical. Story. An evil Queen has a mirror and asks "Magic Mirror on the wall, who is the fairest one of all?" The mirror answers "Snow White". Snow White is the princess of the kingdom and the evil Queen is her stepmother. The evil Queen is jealous
Captain Jack Harkness is a fictional character in the British television series "Doctor Who" and "Torchwood". He is played by actor John Barrowman. He was first in "Doctor Who" in the 2005 episode "The Empty Child" and is in the show throughout the rest of the 2005 series as a companion of the Ninth Doctor. Jack later becomes the main character in "Torchwood", an adult-themed spin-off of "Doctor Who". He comes back into "Doctor Who" in the 2007 series and he meets the Tenth Doctor, and returned again for the 2008 series. Jack is a time traveller and former conman from the 51st century. A bisexual. In contrast to the wiser and older Doctor, Jack prefers a hands-on solution to the problem at hand. As a consequence of his death and being brought back in the last episode of the 2005 series of "Doctor Who", the character becomes immortal, which does not change during both "Doctor Who" and "Torchwood". Characterisation.  In naming the character, executive producer and head writer Russell T Davies got inspiration from the Marvel Comics character Agatha Harkness, Jack's original appearances in "Doctor Who" were thought of with the intention of forming a character arc in which Jack is changed from a coward to a hero, and John Barrowman consciously minded this in his portrayal of the character. Following on that arc, the character's debut episode would leave his morality as ambiguous, publicity materials asking, "Is he a force for good or ill?" The character is described as both "lethally charming... good looking and utterly captivating", as well as "flirtatious, cunning, clever and a bit of an action man". Within "Doctor Who", Jack's personality is light-hearted, although this changes in "Torchwood"'s first series, where he becomes a darker character. In "Torchwood" Series 1, Jack has been shaped by his ongoing search for the Doctor and also by his role as a leader, in which he is predominantly more aloof. During The second series of "Torchwood", Jack became a much more
Hurricane Fico of the 1978 Pacific hurricane season was a tropical cyclone that caused damage in Hawaii. Storm history. A tropical depression formed on July 7 and organized into the sixth tropical storm of the season the next day. Initially heading west-northwest, it changed direction to almost due west shortly after reaching Category 4 intensity on July 11. After spending over a day at that intensity, Fico decayed and fell back down to a mid-range Category 1 on July 14. Fico then reintensified back to Category 4 strength the next day. The hurricane's strength fluctuated, but Fico stayed a major hurricane until July 17, when it entered the central Pacific as a Category 1. It slowly intensified and became a major hurricane yet again on the 21st. At this point, Fico turned to the northwest and slowly lost strength. The storm dropped to a tropical storm early on July 28, and went extratropical later that day. At a later date, the remnants were enmeshed in a frontal system which headed towards the Aleutian Islands. Fico was a tropical cyclone for 20 days, and travelled a distance of roughly 5500 mi (9000 km), both of which were records. It was also a hurricane for 17 consecutive days. Both of Fico's records have been broken. Hurricane Tina and then Hurricane John outlasted Fico. John also outran its distance record. Impact. Fico never made landfall. Despite this, it pounded the Big Island with 15-30 foot waves doing "considerable damage" to roads and buildings along the coast. Smaller waves also broke on the southern shores of Maui with minimal effects. Six people aboard a sloop were washed overboard and rescued, while a tugboat was driven aground on a reef at Kukuiula. A weakening Fico also caused a sharp wind gradient, producing gusty gale-force winds that blew across the islands, knocking over trees and causing power outages. Fico's extratropical remnants caused heavy rains and gales south of Cold Bay in the Aleutians. The name Fico was retired after this storm and replaced with Fabio in the 1982 season.
