Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed.
Cell P: 5.0×10^−4 m
Cell Q: 3.0×10^−5 m
What is the difference in the diameters of the two cells?
A. 0.047 m
B. 0.05 m
C. 0.00047 m
D. 0.002 m
The difference in diameter of the two cells can be calculated by subtracting the diameter of cell Q from the diameter of cell P:
Cell P: 5.0×10^−4 m
Cell Q: 3.0×10^−5 m
5.0×10^−4 - 3.0×10^−5 = 4.7×10^−4
Therefore, the difference in diameter of the two cells is 4.7×10^-4 m, which is equivalent to 0.00047 m.
The answer is C. 0.00047 m.
