b) Cuál será la Epg de una piedra de 20 g de masa a 50 m de altura? Nota: recordá primero pasar los 20 g de masa a kg​

where's the diagram?

it should be all of them because it asks if you included all of those in your answer

explanation:

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
