Resistivity measurements on the leaves of corn plants are a good way to assess stress and overallhealth. The leaf of a corn plant has a resistance of 1.8M%u03A9 measured between two electrodes placed 20 cm apart along the leaf. The leaf has a width of 3.0cm 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. %u03C1 = SubmitMy AnswersGive Up Part B Is this greater than or less than the resistivity of muscle tissue in the human body? Is this greater than or less than the resistivity of muscle tissue in the human body? greater less Su

Explanation / Answer

Apply R = pL/A

1.8 X 10^6 = (p)(.2)/(.03)(2 X 10^-4)

p = 54 Ohm m

For human muscle tissue, the resistivity is about 1.7 Ohm m so the leaf has a greater resistivity
