Classify the following measures as scalars and vectors
(i) 20 m north-west
(ii) 10 newton
(iii) 30 km/h
(iv) 50m/s towards north
(v) `10^(-19)` coloumb

Explanation

To classify the given measures as scalars or vectors, we need to understand the definitions of scalars and vectors:

- **Scalar**: A quantity that has only magnitude (size) and no direction.
- **Vector**: A quantity that has both magnitude and direction.

Now, let's classify each measure step by step:

### Step 1: Classify 20 m north-west
