A student calculated the volume of a solid metal bar by volumetric displacement of water. The student calculated a volume of 22.7 cm3. The actual volume of the bar is 19.3 cm3. Determine the percentage error for this student's calculation.

17.6% is the percentage error

Explanation:

The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:

|Measure - Real| / Real * 100

In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:

|22.7cm³ - 19.3cm³| / 19.3cm³ × 100

the solar system used to have much dust particles option no d

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).
