Physics assignment Aim To determine which 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

as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are silver‚ gold‚ and aluminum. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Aluminum and most other metals do not conduct

In her book “The Conductor as a Leader”‚ Ramona Wis outlines many idea and concepts regarding how to be an effective leader. Many of her ideas seemed particularly profound to me as I read‚ but a small list seemed to stand out above the others. These points stood out to me often because I could relate them to experiences in my own life and conceptualize how their application would have changed an experience for myself. The first point‚ and the most foundational to the book‚ was the entire notion

helped kids and adults with nowhere to go. Harriet Tubman was the conductor of the Underground Railroad. During a ten-year span she made 19 trips and freed over three hundred slaves. Also‚ in all of her trips she has never lost a single passenger. Everyone who attempted to escape through the Underground Railroad succeeded. Harriet Tubman was the most well known conductor of the Underground Railroad. By 1856‚ the reward for the capture of Harriet Tubman was up to $40‚000. Harriet Tubman was a very

Being a conductor of a school band was one of my memorable event of my childhood. I was a freshman at Happy Palace High School. It was summer of 2002 when my high school was having a sports tournament. During that time‚ school held a selection process for band conductor. It was an opportunity for me to improve my self-esteem and confidence. I decided to participate and gave my name to the selection team. The selection process required each participant to perform a band conductor role by using

Harriet Tubman Interview I interviewed Harriet Tubman; a Conductor on the Underground Railroad. I interviewed this person to learn new information about her. This information will help me organize and outline my essay. I asked a total of twenty-six questions‚ gathering the answers to them. The information that I found were surprising‚ interesting‚ and significant to her character. The most surprising facts that I have learned from this research was that Harriet Tubman became a spy

Conductor Investigation Experiment LabReport Introduction This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism Aim To determine the effect of the length of the wire on the ampere of the electric current. Hypothesis Nichrome is an alloy(a metal made by combining two or more metallic elements)

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes
