States that all matter is made of tiny particles that are in constant motion

All matter is made up of 'atoms', which are generally treated as tiny particles, although they have been shown to also have the properties of waves (just like light has both p … article and wave nature). They are constantly in motion, and move faster in matter at a higher temperature.

b would be the answer

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 .
