The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Measuring a Coil of Wire with Ohmmeter and Balance A coil of fine copper wire has a resistance of 6.94- and a total mass is 14.3 g. What is the diameter d of the wire and what is its length L? (The density of copper is 8.96 g/cm'.) Diameter d = mm abc in(x Ox10 Submit Reset Reset All .See Table 25-1 for the resistivity of copper. .Model the wire as a long cylinder of diameter d and length L. Write one relation for its mass, another for its resistance--from these two relations, you can determine the two desired quantities. 7 Length L = m abc in(x Ox10 Submit Reset Reset All
