Answer :
To find the thickness of the tissue in inches, we need to follow a series of conversions from Ångstroms to meters and finally to inches.
Step 1: Convert Ångstroms to meters.
The thickness of the tissue is given as 70 Å. We're informed that 1 Å = 10^{-10} m.
[tex]70 \, \text{Å} = 70 \times 10^{-10} \, \text{m}[/tex]
Thus, in meters:
[tex]70 \, \text{Å} = 7 \times 10^{-9} \, \text{m}[/tex]
Step 2: Convert meters to inches.
We know that 1 meter is equivalent to 39.4 inches.
[tex]7 \times 10^{-9} \, \text{m} \times 39.4 \, \text{in/m} = 2.758 \times 10^{-7} \, \text{inches}[/tex]
So, the thickness of the tissue is approximately [tex]2.758 \times 10^{-7}[/tex] inches.
Therefore, the original tissue thickness of 70 Å is approximately [tex]2.758 \times 10^{-7}[/tex] inches when converted.
