Unreasonable Results

Avg difficulty 2.5

Note: Data taken from figures can be assumed to be accurate to three significant digits.

Two resistors, one having a resistance of 900 kΩ9 \text{00 k}\Omega, are connected in series to produce a total resistance of 0.500 MΩ0 . \text{500 M}\Omega. (a) What is the value of the second resistance? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
