Question 1 Report

which of the following is a scalar quantity?
Answer Details
A scalar quantity is a physical quantity that has only magnitude, but no direction. Therefore, it can be represented only by a number (positive or negative) and a unit. Distance is a scalar quantity as it only has magnitude and no direction associated with it. The other options - tension, weight, impulse, and upthrust are vector quantities as they have both magnitude and direction associated with them.
