Which metric prefix corresponds to a multiplier of 1.0 × 10^{-15}?

• A. femto
• B. nano
• C. pico
• D. atto

Answer: (A)

Verified step by step guidance

1. Recall that metric prefixes represent powers of ten and are used to express very large or very small quantities in a more manageable form.
2. Identify the exponent in the given multiplier: \(1.0 \times 10^{-15}\), which means the quantity is scaled by ten to the power of negative fifteen.
3. Match this exponent to the standard metric prefixes: for example, nano corresponds to \(10^{-9}\), pico to \(10^{-12}\), femto to \(10^{-15}\), and atto to \(10^{-18}\).
4. Since the multiplier is \(10^{-15}\), the correct metric prefix is the one associated with \(10^{-15}\), which is femto.
5. Therefore, the metric prefix corresponding to \(1.0 \times 10^{-15}\) is femto.
