Answer:
2.75x10⁻¹⁰m
Explanation:
By scientific notation, we have to express 0.000000000275 m in powers.
This can be done by counting the number of zeros after the decimal and the number after 0 which is 2.
from 2 to the decimal point, we have 10 characters
so we express it scientifically as,
= 2.75x10⁻¹⁰m
for easy understanding. i have added an attachment to help you out on how to do this.
