Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health. The leaf of a corn plant has a resistance of 2.1 M Ohm measured between two electrodes placed 20cm apart along the leaf. The leaf has a width of 2.8 cm and is 0.20 mm thick.
What is the resistivity of the leaf tissue(Value and Unit)?

To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”
Look for the equation that relates resistance (R) to resistivity.
The unit of resistivity is usually ohm-centimeters
