How does the length of a wire affect its resistance? Introduction: This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go through the main definitions‚ to get a better knowledge of what is going to happen. However I will plan it out first to show each step of how I started‚ and then go into detail about the results and what the investigation on a whole has showed me. I shall then conclude my findings and present them with

THE FINANCIAL CRISIS OF 2007- 09‚ EFFECT ON THE ECONOMY OF JAPAN Japan is among one of the most rapidly growing economies in the world. The economy is primarily dependent upon the service sector which is highly developed followed by the manufacturing and industry sector. The country is rich in new and innovative technologies which benefit it to endeavour in the competitive era. The overall GDP of Japan in the year 2012 was $5960 billion and the purchasing power parity was $4.617 trilllion representing

thing again‚ go about this very‚ very carefully. Dong rot is nothing to joke about. This is the only body you’ve got‚ so don’t ruin it. Step 3-Decide on what size‚ or gauge you would like to be pierced at. Piercing sizes generally follow the American Wire Gauge standard in which a larger number represents a smaller size. For example‚ genital piercings are generally done from a size 16 to about a size 12‚ though there are always exceptions. A 14 gauge is about 1/16". Step 4-Order your surgical steel

current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the length of the wire is so small that it doesn’t resist any current at all. The length of the wire will be changed by moving the crocodile clip across the wire on a ruler. The independent

Verify your expression by using the experimental results obtained. If your results do not show the expected relationship‚ explain why. In order to derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries a current I‚ we can refer to fig. 10. From

a certain few of Cohen’s that stand above the rest. Songs that were hits‚ and songs that in fact helped shape the period of time they were created in. "Suzanne"‚ "Bird on the Wire"‚ and "So Long‚ Marianne" are a couple of these elite creations of Cohen’s mind. During this paper I will be analyzing the song "Bird on the Wire"‚ interpreting its meaning and explaining what it is saying. This song was one of Cohen’s most famous songs‚ and was very influential during the ’60’s- a time of turmoil and unrest

Many parallels exist between “Man on Wire” and the life presented by Camus in The Myth of Sisyphus‚ but there are some distinct differences between the assertions of Camus and the actions of Philippe Petit. Camus found that we as humans usually act with some motive‚ whether that is appealing to God or to some goal set by social standards‚ to reach some unknown measure of success. To Camus‚ this constant appeal to some ulterior meaning becomes absurd when death is considered‚ because death is when

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting
