Answer 1

To find the difference in the diameters of the two cells (Cell P and Cell Q), we can subtract the diameter of Cell Q from the diameter of Cell P.

First, we have:

• Cell P: \(5.0 \times 10^{-4} , \text{m} = 0.0005 , \text{m}\)
• Cell Q: \(3.0 \times 10^{-5} , \text{m} = 0.00003 , \text{m}\)

Now, we can calculate the difference:

\[ \text{Difference} = \text{Diameter of Cell P} - \text{Diameter of Cell Q} \] \[ = 0.0005 , \text{m} - 0.00003 , \text{m} \] \[ = 0.0005 , \text{m} - 0.00003 , \text{m} = 0.00047 , \text{m} \]

Therefore, the difference in the diameters of the two cells is \(0.00047 , \text{m}\).

The correct response is:

0.00047 m
