Theory behind my experiment Thickness (cross sectional area of the wire)‚ length‚ and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. As long as I use the same type of metal for each wire‚ my experiment will remain fair. Cross Sectional Area The thicker the wire‚ the less resistant it is. This is because there are more electrons in

effect of Length on the overall resistance of a circuit. Research question: How does the length of the conductive putty affect the over all resistance of a circuit? This experiment will be discussing how the length of the conductive putty wire affects the overall resistance of a circuit. The variables for this experiment are being used for a number of reasons‚ however one of the main reasons behind choosing this experiment is investing how length of an object is affected be the resistance. The electrons

factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance. Background

Does peaceful resistance affect our laws positively or negatively? In fact peaceful resistance has a positive impact on our laws. Just like publicity‚ non-violence is supposed to lower the bars of negative effects‚ impacting our laws. The relationship between the american public and laws enforcement has always‚ had a violent nature that as a country has never been able to escape. Yet‚ throughout the years the people of this country have used peaceful resistance to change so much of the mistakes‚

Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

Film: The wire (TV series 2002-2008) The series features the abuse of narcotics from a law enforcer’s‚ abuser’s and a drug dealer’s perspective. Rational choice theory This theory settles on a practical belief that man is an actor who reasons contemplates on benefits‚ means‚ costs and ends then makes a rational choice. Man has a sense comprehensible rationale of free will‚ where he evaluates the risks and benefits for committing a crime. From the excerpts from the film (season1)‚ we see a night

Peaceful resistance to laws positively affects a free society. Since we’re Americans we’ve been learning about American History since we started school. Breaking the law is not always a bad thing. IF the law goes against something you believe in ‚ and you know it’s not right break the law. Yes‚ if you’re caught you’ll be jailed but it’s worth it to stick up for something that you believe in. Take for instance in the Civil Right’s Days when Rosa Parks was fed up with the unequal treatment blacks received
