Which of the following metric prefixes corresponds to 10^{-9}?

• A. milli-
• B. pico-
• C. micro-
• D. nano-

Answer: (D)

Verified step by step guidance

1. Recall that metric prefixes represent specific powers of ten, which help express very large or very small quantities in a more manageable form.
2. Identify the power of ten associated with each given prefix: milli- corresponds to \$10^{-3}\(, pico- corresponds to \)10^{-12}\(, micro- corresponds to \)10^{-6}\(, and nano- corresponds to \)10^{-9}$.
3. Compare the given power of ten, \$10^{-9}$, with the powers of ten for each prefix to find the matching one.
4. Recognize that the prefix corresponding to \$10^{-9}$ is nano-, which is used to denote one-billionth of a unit.
5. Conclude that the correct metric prefix for \$10^{-9}$ is nano-.
