Answer : The diameter in meters is, [tex]5.5\times 10^{-9}m[/tex]
Explanation :
As we are given that the diameter of red blood cells is, 5.5 nm. Now we have to convert it into meter.
The conversion used from nanometer to meter is:
[tex]1nm=10^{-9}m[/tex]
As, [tex]1nm=10^{-9}m[/tex]
So, [tex]5.5nm=\frac{5.5nm}{1nm}\times 10^{-9}m=5.5\times 10^{-9}m[/tex]
Thus, the diameter in meters is, [tex]5.5\times 10^{-9}m[/tex]
