hope it helps u a bit

Answer 2

Answer:

The standard form  is $1.2 \times 10^{-7} m$

Step-by-step explanation:

Given that,

Corona virus's diameter = 0.000000120 m

let's express this in fractional form,

0.000000120 m= $\frac{120}{1000000000}$ m

                          =$12 \times 10^{-8}$ m

                          = $1.2 \times 10^{-7}$ m

To express numbers standard form, the number should be of the form

$x \times 10^{k}$   1≤x<10.

Hence, the given number 0.000000120 m can be representation as  $1.2 \times 10^{-7} m$.
