\[c = \frac{2(s_{2} - s_{1})}{\mathrm{\Delta}t} \cdot \frac{\gamma}{\gamma^{‘}} = \frac{2(s_{2} - s_{1}) \ast 10^{- 2}}{\mathrm{\Delta}t \ast 10^{- 6}} \cdot \frac{\gamma \ast 10^{3}}{\gamma^{‘}}\]
\[u_{A} = \sqrt{\frac{1}{n(n - 1)}\sum_{i = 1}^{n}{(x_{i} - \overline{x})}^{2}} = \sqrt{\frac{1}{6 \ast 5}\sum_{i = 1}^{6}{(c_{i} - \overline{c})}^{2}} = 1.9\%\]
