geological core sample is taken at a coal mine. The sample is a cylinder 20.7 feet long and 5.25 inches in diameter. The geologists run electric current through the sample to find its resistivity, which can be used to determine the quality of the coal. A voltage of 5030 V (5.03 × 103 V) is found to produce 11.4 mA of current through the sample. a. What is the resistance in the coal sample? b. What is the resistivity of the sample?
