Im in gr.12 and my teacher gave us a dry lab to do. I have all the information. But theres a question that i cant answer. So can you please help me. The purpose of this lab is to determine the relationship between the resistance, the length and the diameter of an electrical conductor. This is the data. This table won't come out very good so please try your best to understand it. The data ends up crunched up together for some reason Diameter (cm) Resistance 1/d^2 0.025 15.7 1600 0.04 6.1 625 0.075 1.9 177.7 0.125 0.6 64 The 1/d^2 is when the inverse motion becomes a straight line because we are doing proportionality statements. Anyways this is the question i need help on. When a straight line is achieved which is 1/d^2, write a proportionality statement relating R and d, for a constant length. Using the slope of the graph, write an equation for this proportion. Can anyone help me with this question?
