Classify the following measures as scalars and vectors. (i) \[10\] kg (ii) \[2\] metres north-west (iii) \[{{40}^{\circ }}\] (iv) \[40\] watt (v) \[{{10}^{-19}}\] coulomb (vi) \[20m/{{s}^{2}}\]

(i) \[10\] kg is a scalar quantity because it has only magnitude.

(ii) \[2\] meters north-west is a vector quantity as it has both magnitude and direction.

(iii) \[{{40}^{\circ }}\]  is a scalar quantity as it has only magnitude.

(iv) \[40\] watts is a scalar quantity as it has only magnitude.

(v) \[{{10}^{-19}}\] coulomb is a scalar quantity as it has only magnitude.

(vi) \[20m/{{s}^{2}}\] is a vector quantity as it has both magnitude and direction.
