Question

question 4 of 25 as part of a project for his biology class, alex is studying the motion of a turtle over the course of an hour. he places the turtle at the center of a circular tank. after a few minutes, the turtle hasnt moved and alex ends up drifting off to sleep. when alex wakes up at the end of the hour, the turtle is still at the center of the tank. which of the following can alex conclude about the turtles motion during the hour? a. the turtle traveled a total distance of 0 m. b. the turtles displacement was 0 m in every direction. c. the turtle walked in a circle. d. the turtle did not move.

Explanation:

Displacement is the straight-line distance from start to end position. The turtle started and ended at the tank's center, so displacement is 0 m. Distance (total path) isn't necessarily 0, and the turtle did move (drifted off). No info supports circular motion.

Answer:

B. The turtle's displacement was 0 m
