Apply: An archaeologist finds a golden figurine. How could she determine if the figurine is solid gold without cutting it?

By weighing it

Explanation:

The density of gold is known to be 19.3 g/cc and this was derived by dividing a particular mass of gold by its volume. As the density is already know, the archaeologist can then estimate the size of the figurine. Using the estimated size and the density, the archaeologist should be able to come up with a theoretical weight.

The archaeologist should then weigh the figurine. If the figurine's mass is quite different from the theoretical mass then it probable isn't solid gold.

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
