Which of the below statements are true? a. A person can walk a distance of 12 km and have a displacement of 20 km
b. A person can walk a distance of 20 km and have a displacement of 12 km.
c. The displacement of an object depends on the path taken from its initial
point to its final point.

B

Explanation:

Displacement is the distance from the start point to the endpoint, displacement disregard the path taken or the amount traveled.

if you start at point A, then go to point B, and back to point A, the displacement is zero because you started and ended at the same point.

for this question, pretend you started at point A, went east 20 km to point B, and then west 8 km to point C, your displacement is 12 km. 12 km is the distance between point A and point C.

angle is from normal turned to line of ray
