Answer 2

The option which does not have a direction is :

2. Speed

• Most if not all physical quantities can be distinguished into scalar and vector quantities.
• A scalar quantity is one that can be represented by only a numeric value and doesn't need the aid of a direction. For example: speed
• A vector quantity is one that can be represented by both a numeric value and direction. For example: velocity.
• Though speed and velocity in layman's terms mean the same i.e total distance covered in certain amount of time. Speed is just a numeric value while velocity provides the direction as well as the numerical value.
