A minute later the green car is traveling 60 miles per hour north, the blue car traveling 60 miles per hour south how is the green cars velocity similar to the blue cars velocity? what is the different about their velocities

A) The green cars's velocity has the same magnitude as the blue car's velocity.

B) the difference about their velocity is the direction of the velocity which is 180° in the opposite directions.

Explanation:

Velocity is a vector quantity that has both magnitude and direction. The magnitude shows the size, and the direction shows the path the motion takes.

Both cars have the same magnitude but different directions. The difference in their direction is at a 180°angle.

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 .
