find the resistance of a piece if wire. The piece of wire is my dependent variable throughout the investigation. I changed the length of the wire in order to measure the resistance of each length. Plan In this investigation‚ a simple circuit will be set up to read the voltage and current when the length of the wire changes. The length will range from 10cm-80cm with intervals of 10cm. The length of the wire will be changed by moving the crocodile clip across the wire and checking the measurements with

Mary Emeny’s poem‚ "Barbed Wire‚" depicts war as a negative force‚ destroying every decent aspect of human existence. Written during the Vietnam War‚ the work displays Emeny’s negative views on war. In one way or another everyone experiences and identifies with the presence of war. Although some wars are fought for justifiable reasons‚ every war tears into the lives of those undeserving. The tragic effects of war consume the innocent creating an unconquerable path of entanglement. The physical

Chapter 12 – Completion and reporting on the audit REVIEW QUESTIONS 12.1 What is the process of ‘engagement wrap-up’? Why is it important? The process of engagement wrap-up involves the auditor finalising an open items before issuing their audit report. The finalisation process could include completing additional audit procedures to ensure that sufficient and appropriate evidence is held on which to base the audit opinion. The process usually includes work in the following areas: 1

How the Length of a Wire Affects Its Resistance In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor‚ and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance‚ using
