If an object moves 40 m north, 40 m west, 40 m south, and 40 m east, what's the total displacement?
2 answers:
Answer:
B. 0 m
Step-by-step explanation:
We are given the movement of an object and are required to find the total displacement.
Now, as we know that 'displacement' refers to the length of the shortest path between two points.
i.e. We are required to find the shortest path the object covers.
Now, we can see from the figure below that the given movement,
40 m north → 40 m west → 40 m south → 40 m east,
will bring the object back to the original position ' O '.
Hence, the total displacement will be 0 m.

Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
