The total displacement of the car is 2 meters south
Explanation:
As the car went south 10m, and then went back over it initial path for 8 meters, the actual distance registered in the car's odometer will be 18 m, but as far as vector displacement in its final position, this will be 2 meters south (10m -8m=2m).
Notice that the displacement vector is defined as the final position minus the initial position, which gives a distance of 2 from the origin, in the suoth direction.meters

Explanation:
Sound waves enter the auricle and travel through a narrow passageway called the ear canal, which leads to the eardrum.
Density=m/v so d=22.7/2 which gives you an answer of 11.35
