CHAPTER 31 OCEAN CURRENTS TYPES AND CAUSES OF CURRENTS 3100. Definitions The movement of ocean water is one of the two principal sources of discrepancy between dead reckoned and actual positions of vessels. Water in motion is called a current; the direction toward which it moves is called set‚ and its speed is called drift. Modern shipping speeds have lessened the impact of currents on a typical voyage‚ and since electronic navigation allows continuous adjustment of course‚ there is less need to

The Leeuwin Current is a tropical current‚ consisting of warm‚ low salinity water that affects Western Australia’s coastal waters and wildlife. Currents are part of a large sub circular current system called a gyre. The currents in the Southern hemisphere gyres circulate in an anti-clockwise direction (Skinner‚ Porter & Botkin‚ 1999‚ p.249). There is a current in each of the major oceans that generally flow northwards along the western coast of continents. However‚ the Leeuwin Current flows southwards

Current Balance PHY 114 10/29/2013 Abstract: The purpose of this experiment was to understand the current balance‚ current balance is an apparatus that allows measurement of the small force between two current carrying conductors. It consists of two parallel horizontal bars‚ which are connected in series. The current flows in opposite directions in the two conductors so there is a repulsive force between them‚ by Newton’s third law there are equal and opposite forces on both wires. In the

waking up a single time is a whole different reality. In Washington Irving’s mythological story “Rip Van Winkle”‚ the title of the story / character falls into a deep and long sleep lasting for twenty years. After that twenty years and when Rip wakes up‚ the fashion‚ the government‚ and the architecture of the village have all changed.

“The Devil and Tom Walker” and “Rip Van Winkle” by Washington Irving are two very similar yet different stories. Both of these stories talk about the American Dream and how one can want it but be disappointed when one gets it. Tom and Rip both have wives that are turning points in the stories. They both nag so much that it drives them to crazy things. The imagery in these stories gives a real feel for the scenery and how it interacts with the stories. Van Winkle and Tom both get what they wanted

Rip Van Winkle and the American Revolution Rip Van Winkle‚ the protagonist of the story‚ was a simple‚ good-natured man who is defined by many as “lazy”. In fact‚ his name is often used to refer to anyone who is content to sleep their life away or who spends too much time in a sleepy state. People of the town see him more as a productive type of man that is always willing to lend a hand to his neighbors. He is a very generous man when it comes to helping the community‚ but could care less about

supply electricity to cities in the late 1880s is often called the ’War of Currents ’‚ as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages‚ Edison promoted direct current (DC) for electric power distribution‚ whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison ’s direct current was initially the standard for the United States for electricity distribution

Tesla’s biggest innovation was introducing alternating current as the standard for modern electric power‚ breaking Edison’s monopoly on direct current power. Inventors Thomas Edison and Nikola Tesla were opposite sides of the same coin. Edison‚ a brilliant business man with no formal education and Tesla‚

Contrasting the Two Stories of Rip Van Winkle. The story of Rip Van Winkle was written in 1819 by Washington Irving. It was the first American short story. Robert Coover wrote Rip Awake 153 years later. It is his version of the continuing story of the man named Rip Van Winkle. Although both these stories have obvious similarities there are also many differences. These differences include the setting of the story‚ the character of Rip himself‚ and the mood of the story.
