Here are the solutions to the problems: 23) Which of the following gives the correct addition of the two vectors a and b shown in the diagram above? To add vectors $\vec{a}$ and $\vec{b}$ using the head-to-tail method, you place the tail of the second vector ($\vec{b}$) at the head of the first vector ($\vec{a}$). The resultant vector is then drawn from the tail of the first vector ($\vec{a}$) to the head of the second vector ($\vec{b}$). Option [A] correctly illustrates this method. Vector $\vec{a}$ is drawn, then vector $\vec{b}$ is drawn starting from the head of $\vec{a}$. The resultant vector is drawn from the tail of
