Question

Which measurements are scalar quantities?

Answer 1

Answer. 12 km/hr and 2 m are scalar quantities.

Explanation

Scalar quantities are those quantities which only have magnitude but no direction, for example: speed, time, mass etc.

Vector quantities are the quantities which have both magnitude and direction,for example : acceleration, momentum etc.

5 m northeast and 2 m north are vector quantities telling us magnitude and direction both that is 5 m in north east direction and 2 m in north direction.  

12 km/hr and 2 m are scalar quantities telling us only speed and distance respectively without specific directions.
