Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens

Petit: Sane Wire Walker What do you think when you imagine a man walking on a wire higher than 10 stories high? A French wire walker named Philippe Petit walked over many structures from Notre Dame to Sydney‚ Australia‚ to New York. Through the things he has done‚ people may think he is crazy. However‚ Petit and I think that there is nothing crazy about what he has done. I believe the people/society thinks he is crazy. They see this man up hundreds of feet walking across a wire over famous

The edge of the cliff is 8 feet above the level of the water. The tip of his fishing rod is directly above the edge of the cliff and is 7 feet above the cliff. He lowers his fishing line so that it enters the water at the base of the cliff. The length of his fishing line‚ l‚ which is measured from the tip of his fishing rod to the place his line enters the water‚ and the angle between his line and the water‚ θ‚ are changing as the river carries his line downstream.

Section 1 WHAT IS HAPPENING IN THE WIRES? INTRODUCTION Electricity is usually invisible. Except for lightning and sparks‚ you never see it in daily life. However‚ light bulbs and a magnetic compass can show you when something electrical is happening. By observing their behavior and making a few assumptions‚ you can begin forming ideas about electricity. This type of thinking is called “building a model”. INVESTIGATION ONE: WHAT IS NEEDED TO LIGHT A BULB? 1.1 Activity: Lighting bulbs in a loop

perseverance sets him apart from how most people handle their ambitions. When people desire to do things that are potentially harmful‚ their friends try to convince them otherwise. In Philippe’s case‚ no one tries to sway him. This is because they know it would be impossible to influence his decision. It could also be that his friends see‚ and somehow feel some of the passion that Philippe feels about the subject. The documentary did a great job of depicting just how much Philippe appreciated every
