A solid object is made of two materials,one material having density of 2 000 kg/m³ and the other having density of 6 000 kg/m³.If the object contains equal masses of the materials,what is its average density? A)3 000 kg/m³ B)4 000 kg/m³ C)5 300 kg/m³ D)more information is needed

Question

Quizplus · Accepted Answer

Average density = (density of material 1 * mass of material 1 + density of material 2 * mass of material 2) / (mass of material 1 + mass of material 2)= (2000 kg/m³ * m + 6000 kg/m³ * m) / (2m)= 4000 kg/m³
