Chapter A1, Problem 5E

Interpretation Introduction

Interpretation:

Prefixes are used in order to avoid very small/large numbers. They represent exponential order.

Concept introduction:

◾ Prefixes in units will state the order of magnitude

◾ This is useful for very small or very large numbers.

Given:

$\begin{array}{l}\text{a}\text{.}1.2\times {10}^{-9}m\\ \text{b}\text{.}22\times {10}^{-15}s\\ \text{c}\text{.}1.5\times {10}^{9}g\\ \text{d}.3.5\times {10}^{6}L\end{array}$
