Displacement is used to measure A.
weight
B.
mass
C.
distance
D.
volume

In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. So I believe the answer would be C or distance

Maybe c? sorry if im wrong

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way
