Which prefix corresponds to a factor of 10^-12?

• A. Pico
• B. Femto
• C. Micro
• D. Nano

Answer: (A)

The prefix that corresponds to a factor of 10^-12 is "pico." This is part of the metric system where various prefixes represent specific powers of ten. The prefix "pico" specifically denotes a trillionth of a unit, which is mathematically expressed as 1 picometer = 10^-12 meters. In the metric hierarchy, each prefix decreases by a factor of 10. For instance, "femto" represents 10^-15, while "micro" indicates 10^-6 and "nano" represents 10^-9. This organization of prefixes helps to easily communicate and understand measurements across different scales, particularly in scientific fields. Hence, when identifying the correct prefix for 10^-12, "pico" clearly stands out as the appropriate choice.
