Question

the mass of a paper - clip is 9.4×10^(-5) kilogram. what is that mass in standard form? a. 0.0000094 kg b. 0.000094 kg c. 0.00094 kg d. 0.0094 kg

Explanation:

Step1: Recall scientific - notation to standard - form rule

For a number in scientific notation \(a\times10^{n}\), when \(n\lt0\), we move the decimal point \(|n|\) places to the left. Here \(a = 9.4\) and \(n=-7\).

Step2: Convert to standard form

Starting with 9.4, we move the decimal point 7 places to the left. So \(9.4\times10^{-7}=0.00000094\) kg.

Answer:

a. \(0.00000094\) kg
