Answer:
In scientific notation, that would be;
7.0 * 10^-7 m
Step-by-step explanation:
Here, we want to write the given diameter in scientific notation
Mathematically, that can be done by moving the decimal point to the back of 7
The number of times we move will be counted as negative powers of 10 host
Thus, we have;
7.0 * 10^-7
