Title The Wire is one of the rarest yet most intriguing shows I have ever seen. It captures real life issues that many people tend to push to the side. Ed Burns and David Simon‚ creators of The Wire‚ cover a wide area of problems that vary from police institutions‚ the school system‚ politics and the corner. No matter which side an individual is on or which institution they are involved with‚ only one side can overcome the other. Many people believe that the American dream is one hundred percent

Red wires marks the beginning of The Economist talking to people who might not yet consider themselves to be Economist readers through its marketing and advertising. It was sparked by research undertaken by the magazine last year which discovered that‚ because of the rise in the number of people going on to university‚ there are now over 3 million people in the UK whose interest in world affairs‚ travel‚ news and politics suggests an unconscious affinity with what The Economist reports on every week

Bird on the Wire by Cohen Leonard is a personal song that talks about the great challenges of humanity. The poem first starts off saying that people are very free but still confined by comparing us to birds on a wire. Then the song talks about making mistakes and hurting people but always trying make it up. I believe that this is a sad song about feeling out of luck and down‚ and always trying to find yourself from within. I personally really enjoyed the message the second verse was trying

Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes the electrons harder to

because the electrons would bump into more atoms‚ the longer the wire which is like using up its fuel. Material – different materials inherent resistances as they have more or less atoms in them already. Thickness – Thickness affects resistance because the thicker the wire the more paths the electrons have to avoid the atoms. Therefore the cross sectional area is larger so there is less resistance. Temperature – The hotter the wire is the more energy the electrons have to flow faster. Why do we

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
