Question

question 13 (1 point)which of the following measurements is a scalar quantity?the tension in an elevator cablethe acceleration of a car along a test trackthe instantaneous velocity of a parachutist in free fallthe displacement of a hiker from her base stationthe measured distance between toronto and montreal

Explanation:

Scalar quantities only have magnitude, no direction, while vector quantities have both magnitude and direction.

1. Tension is a force, which is a vector (has direction along the cable).
2. Acceleration is a vector (has direction corresponding to the change in velocity).
3. Velocity is a vector (has direction of motion).
4. Displacement is a vector (has direction from the starting point to the ending point).
5. Distance is a scalar, as it only describes the total length between two points with no associated direction.

Answer:

the measured distance between Toronto and Montreal
