Classify the following measures as scalars and vectors
a.30 km / hr b.50 m/ sec towards north c.`10^(-19)` coloumb

Explanation

(a) 30 {km} / {hr} `rightarrow` speed` rightarrow` scalar

(b) 50 {m} / {sec} toward North `rightarrow` Vector

(c) `10^{-19}` Coulumb `rightarrow` unit of charge `rightarrow` Scalar
