3. Vectors

Find the magnitude and direction of the vector $\overrightarrow{C}=2\overrightarrow{B}\times \overrightarrow{A}$ .

What is the magnitude of the cross product of two vectors $\overrightarrow{a}$ and $\overrightarrow{b}$?

Given two vectors $a$ and $b$ in three-dimensional space, which of the following statements correctly describes the cross product $a\times b$ using its properties (without using determinants)?

Given two vectors $j-k$ and $k-i$, what is their cross product $\times$ using the properties of cross products (not determinants)?
