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.

Humans are naturally savage‚ but their savageness is under constraint by society. This means that people change when civilization is no longer around to constrain their savageness. In Lord of the Flies‚ there is no civilization when the boys are stranded on a jungle island and Golding shows that this allows savage behavior to take over. The boys then become savages and everything becomes chaotic. The constraints of society do not allow for savage behavior‚ and the society created by the boys on the

Factors affecting the resistance of a wire Introduction: Resistance is a force‚ which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this ’RESISTANCE.’ He even came up with a rule for working out the resistance of a circuit‚ which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to

Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful. Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However‚ there are some that can cause infections. As bacteria are exposed to antibiotics over time‚ resistance may develop‚ and the number of antibiotics we have to kill the bacteria decreases as well. Thus‚ it is important to learn

Air resistance is an opposing force often known as drag force. Air resistance acts in the opposite direction to snow skier’s velocity and can either harm or enhance performance of the athlete. The flow of air around an object causes the unavoidable effect of drag and is influenced by the size‚ shape‚ surface‚ and overall speed of an object (John Polson‚ 2013). Air resistance is present in snow skiers and can inhibit their performance in a race greatly if the proper precautions and positions are

Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated

Peaceful resistance‚ as with all forms of protest‚ have both positive and negative effects on America’s concept of a “free society” but upon inspection‚ one can see that in time‚ it is positive. Forms of peaceful resistance can range from a conscientious objection to a law in the form of protesting‚ to simply writing a representative to express one’s opinion on a law. Each of these are opportunities for citizens to exhibit their constitutional rights to organize‚ free speech‚ and perform their civic
