A plane starts its flight in direction $\theta $ with run-way. If the distance covered by it in horizontal and vertical both directions is $600\, m$, then find $\theta $.
Unit vector does not have any .......
How the magnitude of vector quantity is represented ?
If a vector $\overrightarrow P $ making angles $\alpha, \beta\ and\ \gamma$ respectively with the $X, Y$ and $Z$ axes respectively. Then ${\sin ^2}\alpha + {\sin ^2}\beta + {\sin ^2}\gamma = $
The change in a vector may occur due to .....
