A unit can be expressed with a prefix that stands for a power-of-ten multiple or submultiple. Complete Table 1.1 by giving the name and symbol of each prefix and the corresponding power-of-ten multiple or submultiple.
From the list below, underline every unit that is an SI base unit. ampere, coulomb, metre, newton
The potential difference $V$ across the two ends of a uniform metal wire is given by $V = \dfrac{4\rho L I}{\pi d^2}$ where $d$ is the diameter of the wire, $I$ is the current in the wire, $L$ is the length of the wire, and $\rho$ is the resistivity of the metal. For one particular wire, Table 1.2 lists the percentage uncertainties in some of these quantities.

For one particular wire, Table 1.2 lists the percentage uncertainties in some of these quantities. The values in Table 1.2 are used to determine $\rho$ as $4.1 \times 10^{-7}\,\Omega\,\text{m}$. For this value of $\rho$, calculate the percentage uncertainty.
Calculate the absolute uncertainty for $\rho$.
