9. The accepted value of g on the earth is 9.81 m/s What is the percent difference between the accepted value of g and the experimental value calculated using your equation from the graph.
Percent Difference= (The difference between the two values divided by the average of the two
values) X 100

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 .
