Predict how the strength of the force between the cars changes when the wedges are taken away and the cars are allowed to move. Justify your prediction

elements make up everything, and they combine to make compounds.

the answer is c

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

they are all solids.
