Calculate \(\int_{C} 1 d s\), where the curve \(C\) is parametrized by \(\mathbf{r}(t)=\langle 4 t,-3 t, 12 tangle\) for \(2 \leq t \leq 5\). What does this integral represent?
Calculate \(\int_{C} 1 d s\), where the curve \(C\) is parametrized by \(\mathbf{r}(t)=\left\langle e^{t}, \sqrt{2} t, e^{-t}ightangle\) for \(0 \leq t \leq 2\).
