Resistance of a Wire essays

Resistance of a Wire essays The experiment is about finding how the resistance of a piece of wire changes as you increase its length in 15 cm amounts each time. In this piece of coursework, I have been asked to investigate the factors that affect the resistance of a nichrome wire. There are many things that affect the resistance of a nichrome wire but I am investigating how the length of the wire will affect its resistance. Firstly I will explain what resistance is and how it works. Resistance is when electrons travelling in a material collide with the atoms of the material. The collisions between the electrons and the nuclei cause the electrons to move slower, this is called resistance. So, resistance is how hard it is for the electrons move through a wire material. The uncontrolled factors that will affect the resistance of the wire are: Firstly, temperature is a factor. If the wire is heated, the atoms will move around more because there will be an increase in energy. This would cause more collisions between the nuclei and the electrons. The increase in collisions would cause the resistance to rise. The temperature factor would be very hard to control, because the equipment needed to keep a constant temperature has not been given to us. So we will attempt to do this by being as quick as possible when taking the readings so as to have the same temperature throughout the experiment. Secondly, the thickness of the wire is a factor. The thickness of the wire will cause resistance to decrease because of the increase in space in the wire. The increase in space means that there is more space for the electrons to flow freely because there would be fewer collisions with atoms. Thirdly, the material used would be a factor. If the material being used contains atoms with a large numbers of free electrons on the outer shells, then this means there are more electrons available. So, in theory, if the material is dense the number of ...

VANDERBILT Surname Meaning and Origin

VANDERBILT Surname Meaning and Origin The Vanderbilt surname has two very different accepted origins: a topographic surname for someone living near a low hill, from the Middle Low German bulte, meaning mound or low hill.originally Van de Bylt, from Die Byltye, a nickname given to ship-carpenters in Holland.

The Famous VANDERBILT Family The prominent American Vanderbilt empire began with Cornelius Commodore Vanderbilt, born in Staten Island in 1794. His 3rd-great grandfather, Jan Aertszoon (1620–1705), a Dutch farmer from the village of De Bilt in Utrecht, Netherlands, was the immigrant ancestor, arriving in the Dutch Colony of New Netherland as an indentured servant in 1650. When he was sixteen, Cornelius, the fourth of nine children, convinced his parents to lend him $100 to purchase a sailboat so that he could start his own passenger and freight service between Staten Island and New York City, a service that eventually became known as the famous Staten Island Ferry.  Young Cornelius then signed on as an apprentice on a variety of ships in order to master all aspects of the seagoing industry. By the age of 50, his shipping empire had afforded him millionaire status. He then turned to buying up  small railroads and turning them into profitable ventures. At the time of his death in 1877, Cornelius Vanderbilt was worth  $105 million. Anderson Cooper, son of Gloria Laura Vanderbilt, is currently the only known prominent, active descendant of the famous Vanderbilt family.   Genealogy Resources for the Surname VANDERBILT Vanderbilt Family Genealogy: My Fascination with All Things VanderbiltTaneya Koonce, who fell in love with the Vanderbilt family after visiting the Biltmore estate for the first time, has built a comprehensive family tree of the Vanderbilt family, and also links to other Vanderbilt resources.

History - Waiting for Macedonia - Essay Example Macedonian men and women don’t necessarily feel a kinship tie to their land, unlike Bosnians. Changes experienced by the young female engineers in Skopje include the fact that they feel more liberated to do as they please, and less inhibited. Young modern socialist women in Macedonia are classified on the upper level of the social strata in comparison to Albanian women of the village, who are sometimes pillaged by war, adversity, and infirmity. Unlike women in the European Union, those from Macedonia and Albania are generally regarded as lower-class – but that might be because the countries that they are from in Southeastern Europe are less highly-regarded due to their lower socioeconomic status. Another personal identity that is portrayed in the book is religion. Religion is more relegated to a status that is separated from the state in Macedonia, and people learn to get along with each other even though they are from different religious backgrounds. Religion, in the m ovie, is portrayed as a necessary part of life. In Bosnia, everyone is split up into factions. It might have had a lot to do with the fact that in the early ‘90s everyone in the region had to at least hear about, if not deal with, the Bosnian War. The Bosnian War divided people into three distinct groups: the Bosnian Muslims; the Orthodox Christian Serbians (also known as Serbs); and the Catholic Croatians (also known as Croats). The Croatians were pitted against the Bosnians by the Serbs. But basically, the Serbians were persecuting the Bosnians based on the fact that they were Muslims. President Bill Clinton finally decided to intervene in the Bosnian conflict in order to prevent an even larger genocide from taking place. To be Muslim in Bosnia meant to be the oppressed. To be a Croatian Catholic meant to be caught in the middle between a centuries-old fight between the Orthodox Christian Serbs and the Bosnian Muslims. National Identities Both the book and the film analyze d ifferent elements of national identity as well. Classifications of national identity in Yugoslavia during the existence of the country were never completely solidified because everyone came from different ethnic backgrounds. This only made allegiance to a nationality more difficult to believe in. The uncertainties of life after Yugoslavia, however, were somehow easier to deal with than the fact that much national pride was never lost on many Yugoslavians who were able to assimilate by ethnic groups. Religion can sometimes pose as nationality in the sense that, if someone is a Muslim, they might automatically assume that they are Bosnian. Thus, in a sense, in that region of the world one’s religious identity gets fused with a nationality even though that may not reflect the reality of an individual. In a similar manner – to put it in another way – many people also assume that someone whose religion is Judaism is necessarily an Israeli, but that’s not absol utely true. Nor is it true that someone who is an Israeli is necessarily Jewish –actually, it is the converse. Nothing can be assumed or presumed. While someone may be ethnically Jewish, they may not be a Jewish national (from Israel), and nothing guarantees that someone’s religion is Judaism unless proven otherwise. Therefore, nationality, ethnicity, race, and religion, for some Jewish people, are all one and the same. But certain people do differentiate between
