Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed.

Cell P: 5.0x10^-4m
Call Q: 3.0x10^-5m
What is the difference in the diameter of the two cells?

A 0.002m
B 0.00047m
C 0.047m
D 0.05m

To find the difference in the diameter of the two cells, we need to subtract the diameter of cell Q from the diameter of cell P.

Cell P: 5.0 x 10^-4 m
Cell Q: 3.0 x 10^-5 m

Difference = (5.0 x 10^-4 m) - (3.0 x 10^-5 m)
Difference = 5.0 x 10^-4 m - 3.0 x 10^-5 m
Difference = 4.7 x 10^-4 m
Difference = 0.00047 m

Therefore, the difference in the diameter of the two cells is 0.00047m. The answer is B. 0.047m.
