A certain geophysical technique determines the electrical resistivity of the ground by measuring the voltage, V, and current, I, between electrodes separated by a distance, a. These measurements are related to resistivity by the equation, resistivity = 2ra (VI). If V = 0.512 +0.01 volts, I=0.00684 ± 0.0001 Amps, and a = 1.00 ±0.01 meters, what is the uncertainty in the resistivity. (Note: The units of resistivity are ohm-meters. The numbers in this problem are given in such a way that no unit conversions are necessary.)

Question
1. A certain geophysical technique determines the electrical resistivity of the ground by measuring the voltage, V, and current, I, between electrodes separated by a distance, a. These measurements are related to resistivity by the equation, resistivity = 2za (VI). 1.00 +0.01 meters, what If V = 0.512 +0.01 volts, I–0.00684 ± 0.0001 Amps, and a = is the uncertainty in the resistivity. (Note: The units of resistivity are ohm-meters. The numbers in this problem are given in such a way that no unit conversions are necessary.)
