The vectors \( \vec{u} \), \( \vec{v}\), \( \vec{w} \), \( \vec{z} \) are indicated in a cube shown in the figure. The cube edge length is \( 1 \). Find the dot products of: \[ \vec{v}\cdot\vec{z}\text{ ,}\ \ \vec{u}\cdot\vec{v} \text{ ,}\ \ \vec{w}\cdot\vec{u}\]
\( \vec{v}\cdot\vec{z}=1 \), \( \vec{u}\cdot\vec{v}=0 \), \( \vec{w}\cdot\vec{u}=1 \)
\( \vec{v}\cdot\vec{z}=\frac{\sqrt2}2 \), \( \vec{u}\cdot\vec{v}=1 \), \( \vec{w}\cdot\vec{u}=\sqrt3 \)
\( \vec{v}\cdot\vec{z}=\sqrt2 \), \( \vec{u}\cdot\vec{v}=0 \), \( \vec{w}\cdot\vec{u}=1 \)
\( \vec{v}\cdot\vec{z}=1 \), \( \vec{u}\cdot\vec{v}=1 \), \( \vec{w}\cdot\vec{u}=\sqrt3 \)
