Question

DNA’s diameter is 0.000000002 meters what is the measurement in scientific notation

Answer 1

Answer:

$d=2\times 10^{-9}$

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 :

$N=m\times 10^n$

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,

$d=2\times 10^{-9}$

Hence, the diameter of the DNA is $2\times 10^{-9}$.
