If an object moves 40 m north, 40 m west, 40 m south, and 40 m east, what's the total displacement?

80,000 Is the answer I believe

The displacement of the object is 0, because the object ends up in back in its starting position. The 40 m north and 40 m south will cancel out. Similarly, the 40 m west and 40 m east will cancel out. Even though the object did travel, it ended up in the same position at the end of its journey as it was in its beginning position. That is why the objects displacement is 0 m

The answer to this is decibel
