Given:
Diameter of corona virus = 0.000000120 m
To Find:
The diameter in standard form.
Solution:
The given numerical problem can be solved by the following method.
The standard form of any number is expressed in terms of powers of 10 multiplied with a decimal number with atleast one number between 1 and 10 before the decimal point.
To convert the given decimal number into standard form, we first shift the decimal point.
On shifting 7 places to the right,
1.20 × 10-⁷ m
When we shift two more places,
120 × 10-⁹ m
This can be expressed in nanometre as
120 nm.
Hence, the standard form of the diameter is 1.20 × 10-⁷ m.
