An electrician cuts a 10-meter-long copper wire having a density of 8.9 g/cm3 into 10 equal parts. What is the density of each small part? One-tenth of 8.9 g/cm3 since density is an intensive property One-tenth of 8.9 g/cm3 since density is an extensive property 8.9 g/cm^3 since density is an intensive property 8.9 g/cm3 since density is an extensive property
