The free-fall acceleration on the surface of the moon is approximately one-sixth of the free-fall acceleration on the
surface of Earth Compare the period of a pendulum on the
moon with that of an identical pendulum set in motion on Earth

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 .
