Two forces are acting on a particle at the origin. One force is acting in the first quadrant at 45o with 20 N and the other is acting in the second quadrant at 45o with respect to the negative x-axis also with 20 N. If the mass is 2.0 kg, the net force on this mass is Group of answer choices 10 N 15 N 40 N 28 N zero N

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 .
