Answer:
[tex]d=2\times 10^{-9}[/tex]
Explanation:
It is given that, DNA's diameter is 0.000000002 meters. We need to convert the diameter into scientific notation.
Any number can be written in the form of scientific notation as follows :
[tex]N=m\times 10^n[/tex]
Where, m is a real no and n is any integer
We have, d = 0.000000002 m
There are 8 zeroes before 2. We can shift the decimal after 2 so as to write it into scientific notation.
So,
[tex]d=2\times 10^{-9}[/tex]
Hence, the diameter of the DNA is [tex]2\times 10^{-9}[/tex].
