GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor‚ in this case wire‚ by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

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

investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes‚ current changes‚ as Ohm’s law: I = V/R. If one part of an equation changes‚ the equal must be done to the opposite side. To detect how resistance affects current‚ I must first discover what factors affect resistance. These factors are: · Length of the wire if a wire is longer; there are more particles for electrons to move through‚ and therefore more resistance. · Conductivity

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

in animals‚ people could still assume it exist in human due to MRI of human brain had very similar patterns with animals when observing behavior. One study done by Iacoboni in 2004 related to mirror neuron could be considered as another example of how physiological processes get influenced by environment. First‚ the aim of Iacoboni’s study was to determine if simply observing an emotion that’s expressed on a person’s face could cause the brain of observer to start become stimulated. The researcher

Diabetes is a chronic disease that affects the endocrine system‚ and occurs when your blood glucose‚ also known as blood sugar‚ is too high. Disease is a very common and serious disease that affects approximately 29.1 million people in the U.S.‚ let alone the 86 million people that have prediabetes‚ without even noticing it‚ (MedicineNet.com). To understand diabetes‚ it is important to understand the role of insulin and glucose in the body. Glucose‚ or sugar‚ is an important source of energy for

Rain forests have an average temperature of 80 degrees fahrenheit. The temperature may feel hotter due to the high humidity rate. Rain forests can receive 100 to 300 inches of rain per year! The rain forest can produce good

September 17‚ 2008 Wednesday Lab I am writing about the testing of sizes on Paramecium caudatum and bursaria and how they differentiate from one another. In comparing the two specimen’s size I found that the Paramecium caudatum was larger in size than the bursaria. Paramecia are unicellular organisms and are usually less than 0.25mm in length and covered with minute hair-like projections called cilia. They are characterized by their cilia which are used in locomotion and
