A jogger runs 224 meters eastward, then 156 meters westward, then 84 meters eastward, and finally 248 meters westward.

What is the distance, magnitude and the direction of the displacement?

Explanation:

Distance is the length of the path traveled.  Displacement is the difference between the final position and initial position.

Distance = 224 m + 156 m + 84 m + 248 m = 712 m

Displacement = 224 m − 156 m + 84 m − 248 m = -96 m

Displacement = 96 m westward

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
