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.

Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter

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‚

procedure‚ you actually made a cylinder of M&Ms. The cylinder was rather "smushed‚" and the height of the cylinder was the thickness of an M&M. Recall that the equation for the volume of a cylinder is V = (3.14)r2h. A. Rearrange the equation for "h." Show your work.H=v*(3.14)r^2 B. Using the data from Table 1 and your equation‚ calculate the average thickness (height) of an M&M for each trial. Record your calculated values in Table 1. Hint: Students often forget that they must

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

Coursework - Resistance of a Wire Coursework Introduction (Theory) In this piece of Coursework I am going to investigate the resistance in a piece of wire. Resistance is the force that slows down the flow of electrons; this can be due to electrons colliding. The total length of the wires will affect the amount of resistance. The longer the wire‚ the more resistance that there will be. This is also true for thickness of wire; the thinner the wire is the more resistance. Resistance is measured

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
