Which of the following is the multiplier associated with the metric prefix atto-?

• A. 10^{-9}
• B. 10^{-15}
• C. 10^{-12}
• D. 10^{-18}

Answer: (D)

Verified step by step guidance

1. Understand that metric prefixes represent powers of ten that scale units up or down by specific factors.
2. Recall common metric prefixes and their corresponding powers of ten, such as nano- (\$10^{-9}\(), pico- (\)10^{-12}\(), femto- (\)10^{-15}$), and atto-.
3. Identify that the prefix 'atto-' corresponds to a very small scale, smaller than femto- and pico-.
4. Recognize that 'atto-' is associated with the multiplier \$10^{-18}$, which means it scales a unit down by a factor of one quintillionth.
5. Confirm that among the given options, \$10^{-18}$ correctly matches the 'atto-' prefix.
