The dot product between two vectors is a scalar quantity. If the result of the dot product between two vectors v and w is zero we can assure that the vectors v and w are perpendicular. Answer and Explanation:1 Given: $$\begin{align} \vec u &= \left <2, 2, 1 \...
SI unit of average speed is m/s, and is a scalar quantity, which means it has only magnitude. Solved Examples on Average Speed 1. A train travels at a speed of 300 km/hr for 2 hours and then slows down to 220 km/hr for the next 2 hours. What is the average speed of the trai...
