a uniform meter stick balances on a fulcrum placed at the 70 cm mark when a weight w is placed at the 90 cm mark. what is the weight of the meter stick

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 .

the answer is a 3.8cm
