Resistance of a Wire :: Papers

Resistance of a Wire Introduction Resistance is the opposition a material offers to the flow of electricity. The electric resistance of an object is not only by what material its made of, but also by its shape. A very thin copper electrify has more resistance than a thick copper outfit of the same length. A very long copper wire has more resistance than a short one of the same thickness. Resistance is measured in Ohms. Variables There were three variables that our group was able to choose from the length of the wire, the area of the wires cross class (thickness) or the type of wire (constantan or nichrome). All of these variables are able to change the resistance of the wire. Here are my thoughts and predictions on what would happen to the resistance of the wire as you change the variables. I think that if you change the length of the wire then the resistance would increase as the length increased but the online would decrease. If you changed th e thickness of the wire then the resistance would decrease as the wire got thicker but the current would increase. If you change the type of wire then you will attain different results, as there may be more or less resistance between types of wire. To study the resistance or wire we experimented on changing the length of nichrome wire. We measured the volts and amps over 1 metre I worked out the resistance using my calculator. We carried out this experiment 5 times to reap the results fair. We let the wire cool down a bit between doing the experiments, as its temperature did tend to increase as we got to the end of each experiment. Analysis We took a set of practice results before starting the experiment. Here they are. Wire Volts Amps Ohms 10cm 2.63 2.53 1.04 50cm 4.16 0.82 5.

Crushed Dreams in The Glass Menagerie Essay -- Glass Menagerie essays

Crushed Dreams in The Glass zoological garden Tennessee Williams is cognize for his use of symbols, tension, and irony. Williams uses all of these components to conduct the central theme of The Glass Menagerie - hope followed by despair. Each of the characters has dreams that argon destroyed by the harsh realities of the world. As the narrator blatantly admits, since I have a poets weakness for symbols, symbols are central to The Glass Menagerie (Williams 30). Symbols are merely concrete substitutions used to express a particular theme, idea, or character. One major symbol is the firing off ladder which has a separate function for each of the characters. This incinerate run provides a gist of escape for Tom from his cramped apartment and nagging mother. Therefore, the fire escape for him represents a path to the outside world. For the gentleman caller, the fire escape provides the means through which Jim can enter the Wingfield apartment, thus entering their lives. For Am anda, the fire escape allows Jim to come into the apartment and prevent Laura from becoming a spinster. The significance of the fire escape for Laura is that it is her door to the inside world in which she can hide. It is ironic that when Laura does abdicate the security of her apartment, she falls.

The Europeans Acceptance of Imperialism Essay -- Age of Imperialism

If we look at the valet de chambre we live in today, we notice that it has changed dramatically oer the years since the 1800s. Many historical events from the past take up changed the way we live today. It has turned our knowledge and our lifestyle into something so ordinary, that we are not even aware of it. For instance, our education system, since we were kids we were always taught to read the map a certain way so that when we grew up and started to draw and label the map of the world, we always put Europe in the center. Our teachings have taught us to view the world through such a Eurocentric perspective. Furthermore, it is important to understand that our ways of practicing various fundamentals of life regard the historical background we come from. In the past the European powers had an impact on legal age of the world. These European powers adopted a policy of Imperialism. Imperialism is an act that takes place when one with greater dominance takes over another nation in or der to control its economical, political cultural, industrial and social life.

Essay --

I watched a documentary on Youtube about the Super Volcano that lies beneath the oldest national park. I have always been very interested in this varianceicular volcano because it is so close to my home in Colorado. I found this documentary to be thoroughly informative while being left extraordinarily frightening. All of those wonderful geysers, boiling mud pits, and pools of heated sulfur, all get their power by the magma chamber a mere 5 miles below the surface. This Magma chamber contains over one million tons of partially molten rock. Volcanologists have explored all move of Montana, Idaho, and Wyoming. The discoveries that they made would shock the world, they have found 3 calderas from past flacks. The last and biggest eruption ever known to man, taking place 64,000 years ago, left a huge Caldera towards the North part of Wyoming up into Montana that can only be fully seen in the air. The effects of this eruption were felt most intemperately in a radius of 300 miles however there were devastating effects were felt worldwide and they lasted up to 9 years. This caldera is the biggest ever known to mankind, and with part of it overlapped with a caldera from a previous, smaller eruption, ultimately creating an even larger caldera. This is the foundation for a globally spread disaster. Theres only one eruption that can almost match the destruction that would come when the pressure starts to build and everything explodes. That is the Eruption in Toba. We know from this eruption that when a supervolcano erupts the immediate effects willing take place in a Possible 450ft. Radius. A super volcano differs from the typical volcano in the sense that there is no noodle or raise earth where the opening is. Instead, the magma chamber is rumbling ... ...fference of life and death. I liked the production and presentation of the documentary, it was VERY informative and chalked full of facts that I am dying to share with everyone now. If I could change anything about the message that they sent across would be that, yes if an eruption were to happen (which it probably will quondam(prenominal) in the not so far away future however far away that may be, anywhere from a year from now, to one railyard years from now) our future would be bleak and most likely the earth would be desolate. But I would have added in the factor and hope that comes with knowledgeable that Gods in control and it was his will for this to happen. Overall It leaves me knowing everything I would have ever want to know about the Yellowstone Supervolcano. Yet in a strange way, it leaves me wanting to explore deeper into the mystery that lies just beneath our feet.

Our Time Machine :: essays research papers

Our Time MachineH.G. Wells once wrote a novel called The Time Machine, it was published in 1895. This kindle little adventure featured a device that had power over time. Who knew that in 2001 we too would have such a device? One conception that has made it evident that we have reached the twenty first century is named Tivo. With this, one has the ability to pause, fast forward, and essentially tamper with live television. This gadget is, in a sense an actual time machine. Were living in an age where the word digital seems to come into play with every new invention. Digital applied science admits all types of electronic applications that use information in the form of numeric code. This information is usually in something called a binary codethat is, code that freighterful be equal by strings of only two numeric characters. These characters are usually 0 and 1. Devices that put to work and use digital information include personal computers, calculators, automobiles, traffic l ight controllers, compact disc players, cellular telephones, communications satellites, and now Tivo. Most of the information we sense is parallel of latitude in naturethat is, it varies constantly, and an blank number of values can be assigned to the information. For example, the brightness of a light bulb dimmed gradually from on to off could be considered analog information. This infinite number of brightnesses can be broken up into ranges. If the possible brightnesses are broken into two ranges, then the values 0 and 1 can hold digital information relating to the brightness of the bulb. However, each of the two digits still represents a countless number of analog values. The ranges of brightnesses can be divided once more and again, until there are thousands of ranges of values, each of which can be represented by a numerical value. Once analog information has been broken up into digital information, it is impossible to perfectly reverse the process and re-create all of the po ssible analog signals from the corresponding digital signals. This is why most analog signals are represented by a great number of digital information levels. For example, the sound stored as digital information on a CD is broken ingest into 65,536 levels. A CD player translates the digital information into analog information so that a speaker can convert it into sound waves. Some devices process digital information using a tiny computer called a microprocessor. It performs calculations on digital information and then makes decisions based on the results.
