Question: 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 2.3 MΩ measured between two electrodes placed 20 cm apart along the leaf. The leaf has a width of 2.9 cm and is 0.20 mm thick.
Part A: What is the resistivity of the leaf tissue? Express your answer to two significant figures and include the appropriate units.
Ï = ________
Part B: Is this greater than or less than the resistivity of muscle tissue in the human body?
(A) greater or
(B) less
