Question

Which measurement of length is the smallest?

9 x 10–6 m
7 x 10–5 m
7 x 101 m
9 x 102 m

Answer 1

I guess A is the correct answer

Answer 2

Answer : The correct option is
`9* 10^(-6)m`.

Explanation :

Length : It is defined as the measurement of any object from end to end.

The length is measured in many terms like in Meter, Centimeter, Kilometer, etc.

`9* 10^(-6)m=0.000009m`

`7* 10^(-5)m=0.00007m`

`7* 10^(1)m=7m`

`9* 10^(2)m=90m`

The higher the negative power of 10, the lower will be the value.

And the higher the positive power of 10, the higher will be the value.

Therefore, the smallest value of length is
`9* 10^(-6)m`.
