Resistivity of a Wire.

PHYSICS ASSESSMENT - RESISTIVITY OF A WIRE PLANNING PRELIMINARY RESEARCH What is resistivity? - Resistivity is a fundamental parameter of the material making up the wire that describes how easily the wire can transmit an electrical current. High values of resistivity imply that the material making up the wire is very resistant to the flow of electricity. Low values of resistivity imply that the material making up the wire transmits electrical current very easily. Ohms law states that if the cross section of the wire is uniform, then the resistance is proportional to the length and inversely proportional to the area of the cross section. There are four variables that affect the resistance of a wire. These factors are thickness/diameter, length, material and temperature. The two factors I am going to look at are thickness and length because the effect on the resistance is more measurable than the effect of resistance with material and temperature. The thickness/diameter of the wire will have an affect on the resistance of a wire. This is because the electrons have to squeeze together more to pass through a thin wire than they do to pass through a thick wire. The length of a wire affects the resistance because if you double the length you double the resistance. So for this experiment, it would be sensible to keep the length of the wire constant so you are

Examine the Victorian stories

Examine the Victorian stories "The Man with the Twisted Lip", "The Adventure of the Speckled Band", and "The Red Room". Consider the effects that each writer has created and how they add to the plot, setting and atmosphere. The Victorian era was a time of great change; industrialisation, imperialism, scientific discovery. These changes reflect in the new topics of contemporary literature. In this essay I am going to look at the effect created by Arthur Conan Doyle and H G Wells in three short stories, analysing how this effect has added to the plot, setting and atmosphere. In order to fully understand the ideas behind these short stories it is detrimental to overcome our ignorance of past culture. Sir Arthur Conan Doyle was surrounded by a London of crime. The police force was almost totally ineffective and the idea of a super detective, able to solve every crime was comforting to the populace. John Dean the philosopher once said "People believe what they want to believe." It sounds so simple yet in practice it represents a huge part if how the human works. For example if I were to prank call someone and tell him/her that she had won tickets for a two week holiday in Australia, he/she would believe me because they wanted it to be true. In relation to Sherlock Holmes, I feel the populace of the time were trying to imagine an actual Sherlock Holmes, as a psychological

The Significance Of The Conch

The Significance Of The Conch In the novel the 'Lord Of The Flies,' the conch is seen as a beautiful object, a part of the natural world, which, until the boys had landed, was untouched and unspoilt by humans. Right up until, about the last hour on the island, it had represented a symbol of authority, common sense, security and democratic discipline. Its destruction at the end symbolises the wilful destruction of order and rational behaviour. In Greek mythology, the god of the sea used it to calm or raise the oceans. This shows how powerful the conch is portrayed in fiction. As you read on in the book however, it's plain to see, which boys respect the conch, like Ralph, how some just obey it, like some of the littleuns, and how others, like Jack simply disobey it. It's the latter people who eventually challenge and disregard its authority. As the conch's popularity drops, and its colour is slowly lost, you see how the boys lose their innocence. The conch's 'epic' journey starts when Piggy bursts into a 'decorous excitement.' (p21). Ralph had spotted a creamy shell in amongst the weeds. This find is the start of the civilization on the island. Piggy has already acquired the knowledge of the conch, and many other valuable things in his life. He recognises the conch's value immediately when he says 'It's a shell! I seen one like that before. On someone's back wall. A conch

Should the UKadopt a system of PR for General Elections?

Should the UK adopt a system of PR for General Elections? In our current system, First-Past-The-Post (FPTP), there are only two parties capable of being elected into government, the Labour and Conservative parties, perhaps including the Liberal Democrats as a potentially influential party. In our 'democratic' society, if you do not vote for one of these three parties, your vote has been wasted. There are only about 250 seats in the House of Commons that regularly veer between parties out of the 650 available, therefore, for a Labour voter in Malvern or a Conservative voter in Ebber Vale your vote has essentially been wasted, either you move to a different constituency or you change parties, otherwise your vote will effectively not count. This raises the question whether a fairer proportional representation system would lead to a fairer government, but as past examples such as the Weimar Republic have shown, proportional representation also holds problems. The result of smaller parties gaining seats is that in order to gain a majority the larger parties must form a coalition government with the smaller who then gain a disproportionate say in government as the larger party needs their support to get legislation through. No government since World War II has been elected on more than 50% of the vote, even the recent 'landslide' victory of Tony Blair's New Labour won with

Both "Lamb to the slaughter" and "The Speckled Band" shares some of the characteristics of murder mysteries. Explain the similarities and differences between the two stories and say which story you think is more compelling to read.

Emily Rice 10Y1 English GCSE coursework Both "Lamb to the slaughter" and "The Speckled Band" shares some of the characteristics of murder mysteries. Explain the similarities and differences between the two stories and say which story you think is more compelling to read. After reading both "Lamb to the slaughter" and "The Speckled Band" I intend to analyse the stories in detail showing their similarities, differences and success in fulfilling my expectations of a murder mystery story, taking into consideration that the two stories were written at very different periods in history. In order to do this I will make comparisons between characters, settings, language and overall story line, etc. I will constantly be considering how writing techniques and styles have changed through time and how this affects the story. Finally, I will attempt to come to a conclusion stating which story is generally most compelling to read. Roald Dahl and Arthur Conan Doyle were very different authors with very different writing styles, but they shared the same love for writing stories with a twist and for pleasing their readers in their own unique ways. They were both born in different centuries, had dissimilar views and were very incomparable for their time. Arthur Conan Doyle knew what the public wanted to read, they wanted to be able to associate with and love the main

How does Willy Russell explore the themes of class and society in Blood Brothers?

How does Willy Russell explore the themes of class and society in Blood Brothers? Willy Russell explores how class can make a big difference to society and people's lives in the play Blood Brothers. Blood Brothers is set in Liverpool during the 1980's. During the 20th century unemployment and poverty was high which lead to a massive gap between the rich and poor. Willy Russell can relate to this as he himself was born outside of Liverpool and was of the working class. The class divide also meant the education of children would suffer as grammar schools were free however the working class must past the lit to gain entry. The pass mask was deliberately made high so the working class cannot go grammar school. This maintains the social system. I will explore in this essay the characters actions, dramatic techniques structure and context through social class and injustice. Willy Russell shows the divisions of society in many different ways. Firstly he starts with Mrs Johnstone. She is quite poor and works for Mrs Lyons. The theme superstition implies that something bad will happen for example there might be a loss. Nothing will ever change what would happen. At times when superstition is used a bad feeling or threatening feeling is left which creates tension. Mrs Lyons uses this to persuade Mrs Johnstone to give her one of the children. Mrs Johnstone is clearly superstitious,

Show how J. B Priestley uses a detective story to create and maintain the interest of the audience and put over a moral message

An Inspector Calls written by J.B Priestley is a play that contains many of the ingredients of a murder mystery. Murder mysteries contain a crime, suspects, victims, setting, murder weapon, evidence, witnesses, detectives, red herrings, cliffhangers, and interrogation. An Inspector Calls contains many of these for example the setting (Birling residence) the inspectors calls to the house and starts questioning the family. J.B Priestley creates interest of the audience by making the play resemble that of a murder mystery. It is like one because the Inspector has his suspects and his victim. The Birling family are the suspects and Eva Smith/Daisy Renton is the victim. The Inspector believed that they all had some involvement with girl to drive her to suicide. The first suspect was Mr Birling, she worked for him at his factory she went on strike because she demanded more money. He refused and gave her the sack. The next was Sheila, her involvement was that the girl worked at a store called Milwards she was lucky even to get that job. Though Sheila complained to the manager and said if you don't sack this girl for being so rude then we withdraw our account from your store. Which obviously meant the girl had to go.

This is known as a three-step stair. The total of the numbers inside the stair is: 55+45+46+35+36+37=254 So the stair total for this shape is 254. The stair number for this shape is stair 35 as the number in the bottom left hand corner is 35. Now we can investigate the relationship between the position of the stair shape on the grid and the stair total. The diagram below is stair 1 as the number in the bottom left hand corner is 1. 21 1 2 2 3 As we see, the stair total for this 3-step stair1 on this 10 by 10-number grid is 50 as 1 + 2 + 3 + 11 + 12 + 21 = 50. Below is the stair shape one square to the right of stair1. This stair is called stair2 as the number in the bottom left hand corner is 1. Stair2 is a translation of stair1 one square to the right. 22 2 3 2 3 4 The stair total for this stair shape is 2 + 3+ 4 + 12 + 13

Sheila's Speech That night was one night I could never forget. It was the night that changed my life forever...

Sheila's Speech That night was one night I could never forget. It was the night that changed my life forever... It was changed by a mysterious inspector whom none of us had ever met before. We didn't even know what he was; was he a regular police officer, a hoaxer, or was he something a lot more than what appeared to the eye? It left me and the rest of the family shocked. It really began at a dinner party to celebrate my engagement to Gerald- my first arrangement to Gerald I should say! I hardly recognise myself now looking back at that silly, happy, charming girl who thought she had reached the pinnacle of her life, how wrong I was. How little did I know about the world, society, other people... It was a nice, pleasant day; one which I was looking forward to for a long time. Never did I even think about something as strange as this happening at that day it was extremely bizarre. It was basically like most days we were all having our silly discussions around the table and just trying to get along with each other, just a bit more special though, more port, the family dressed up in nice new clothes, etc. It was my engagement to Gerald, there was nothing strange or weird expected. I could just imagine looking back at the day, before going to bed and thinking what a nice day it was. We were all just talking about loads of different little things and mainly the engagement of

BTEC National Diploma in Business Exploring Team Development Introduction: In this Assignment I am going to describe how to build cohesive teams that perform well and explain how targets are set and team performance is monitored. I will also assess the value of different methods of monitoring the performance of a team. Task 2 (P2) How to build cohesive teams that perform well The term "cohesive" means unity, coming together, sticking together, while a team is a group of people who comes together in order to achieve a common goal. So "cohesive team" in my own word may be defined as the uniting together, coming together or sticking together of a group of people in completing a set target. To have a cohesive team you have to follow different processes in team building and also monitoring team performance. Team Building This is very important as it ensures the success or the downfall of an organisation. If an organisation employs the right staffs that possess the right skill in the right position then they will be able to perform effectively. There are different processes involved in team building which are: * Recruitment: The recruitment process involves identifying the skills, qualities and competences that will be required in potential team members (Job analysis).
