Answer: The correct way to write 0.0000250 m in scientific notation is [tex]0.0000250 m=2.50\times 10^{-5} m[/tex]
Explanation
The scientific notation is way to represent a very large or very small number in a convenient way.
For numbers without decimal:
It is written by shifting the decimal point to the left until single digit before decimal point is reached and multiplying with number '10' raised to the power equal to number of times decimal point shifted towards left.
For example: Number '2345 ' is written in scientific notation as [tex] 2.345\times 10^{3}[/tex].
For numbers with decimal:
It is written by shifting the decimal point to the right until single digit before decimal point is reached and multiplying with number '10' raised to the power equal to number of times decimal point shifted towards right with negative sign.For example: Number '0.003045 ' is written in scientific notation as [tex] 3.045\times 10^{-3}[/tex].
So, the correct way to write 0.0000250 m in scientific notation:
[tex]0.0000250 m=2.50\times 10^{-5} m[/tex]
