Simple definition of polar vector

In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed

Explanation:

Polar vectors are the type of vector usually simply known as "vectors." In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.

Explanation:

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 .

choosing tennis and golf balls is your inde choice.

their mass and volume are dep
