Arock is placed in a graduated cylinder to determine its volume. the following data are obtained. what is the volume of the rock?
initial volume of water: 13.7 ml
final volume of water: 28.9 ml
15.2 cm3
15.2 ml
15.2 cm
15.2 dm

15.2 mL is the volume of the rock.

Explanation:

Initial volume of the water in graduated cylinder= 13.7 mL

Final volume of the water in graduated cylinder= 28.9 mL

Volume occupied by the rock = x

V + x = V'

Where, V = Inital volume of water

V'= Final volume of the water

x = 28.9 mL - 13.7 mL =15.2 mL

15.2 mL is the volume of the rock.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
