affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)‚ the thickness of the wire‚ and the temperature of the

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement

RECENT TRENDZ IN POWER GENERATION POWER GENERATION FROM ROAD SPEED BREAKER AND FROM SHOES (Recent way to produce power) ABSTRACT: Man in his lifetime‚ uses energy in one form or the other. In fact whatever happens in nature‚ results‚ out of the conversion of energy in one form or the other? The blowing of the wind‚ the formation of the clouds and the flow of water are a few examples that stand testimony to this fact. Of late‚ erratic and perfunctory usage

In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2

THE ROUGH CROSSING by F. Scott Fitzgerald (1896-1940) The Saturday Evening Post (8 June 1929) I Once on the long‚ covered piers‚ you have come into a ghostly country that is no longer Here and not yet There. Especially at night. There is a hazy yellow vault full of shouting‚ echoing voices. There is the rumble of trucks and the clump of trunks‚ the strident chatter of a crane and the first salt smell of the sea. You hurry through‚ even though there’s time. The past‚ the continent‚ is

In episode 3 of The Wire‚ there are a lot of characters that seem to know nothing more than selling drugs and making money. However‚ in this scene starting at 10:41 and ending at 12:41 shows that these characters are bit more complex and two sided than we are shown. This scene starts with a very fast pan of the pit area until the camera finds D’Angelo. This pan of the courtyard shows how unsafe it is‚ and how the characters are being watched and how they should watch their backs. The pan of the

The close up shot of the wire illustrates to the audience that extreme actions are undertaken to create an atmosphere in which she can belong. The barbed wire indicates that intruders aren’t allowed to enter her surroundings as they could severely impair her sense of place‚ thus highlighting that indeed belonging and place are

railroad crossing is where a road crosses through a railroad where the trains can pass through. There are all sorts of signs that warn drivers that there is a railroadcrossing ahead‚ they can be on a post or on the road pavement. The warning signs thatare on the road and on the posts have an “X” and two “R” on the sides of the X. These signs tell you to slow down‚ listen‚ keep the look out‚ and be prepared to stop at a railroad crossing.There are three types of railroad crossing signs‚ which

and watching the additional videos‚ I learned a lot about railroad crossing safety. At first I did not know that this topic was an issue. But through reading and watching the information given to me related to this issue‚ I learned that it is definitely a danger to drivers and passengers who are involved. From the Utah 2014 Driver’s Handbook it states‚ “As the number of driver’s increases‚ more and more people die at railroad crossings.” As seen in the statistics‚ the number of injuries caused by railroads
