This question has multiple parts. Therefore each part has been answered as a separate question on Clay6.com

- A scalar quantity has only magnitude.
- A vector quantity has both magnitude and direction.

Step 1:

We are asked to classify $40^\circ$ as a vector or a scalar quantity.

Clearly $40^\circ$ represents only the angle measure.

It shows only the magnitude,but not the direction.

Step 2:

Hence it is a scalar quantity.
