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

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

B at a point of distance r‚ from an infinitely long wire that carries a current I. Your derivation should include the direction of the magnetic field with respect to the direction of current flow. 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

In this photo‚ including myself‚ there are five people. I am on the far left‚ and one of the four persons on the inside of a barbed wire gate located at a motel about thirty miles south from Tegucigalpa. I carried a large bottle of water and wore an aged Redskins’ football t-shirt. These four people on the inside of the gate are in their night wear and etc. The one person behind the gate is wearing semi presentable clothes (a tucked in blue collared shirt‚ a buckled white pair of cargo shorts and

Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the

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

Being a part of a group of children having to adapt after being trapped on a island with no surrounding civilization is an unimaginable situation. However‚ William Golding shows just how terrifying it can be in his novel‚ Lord Of The Flies‚ by his use of symbols to represent hardships. The main symbols‚ which best portrays characteristics are the fire and the conch; symbols leadership and confidence. <br> <br>Ralph feels the need to create a better place as he attempts to get everyone home.
