A solid object is made of two materials,one material having density of 2000 kg/m³ and the other having density of 8000 kg/m³.If the object contains equal volumes of the materials,what is its average density? A) 3000 kg/m³ B) 3200 kg/m³ C) 5000 kg/m³ D) more information is needed

Question

Quizplus · Accepted Answer

The average density of the object is calculated by taking the sum of the densities of the two materials and dividing by 2 since they have equal volumes. Average density= (2000 kg/m³ + 8000 kg/m³)/2 = 5000 kg/m³. Therefore, the correct choice is C.
