1.0 GENERAL PHYSICS P2\&P3 QUESTIONS
Compiled by: R.T.Tuga
Q1: NOV 2001 P2
The unit of a physical quantity may be shown with a prefix. For example, the prefix micro $(\mu)$ has the decimal equivalent $10^{-6}$, so that 1 microamp $(1 \mu \mathrm{~A})$ can be written as $10^{-6} \mathrm{~A}$. Complete Fig. 3.1 to show each prefix with its corresponding decimal equivalent.
\begin{table}
prefix | decimal equivalent
pico | $\ldots \ldots \ldots \ldots \ldots$.
micro | $10^{-6}$
giga | $\ldots \ldots \ldots \ldots \ldots$
$\ldots \ldots \ldots \ldots \ldots .$. | $10^{12}$
