Question

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

Answer 1

`\rho_(avg)=4000kg/m^3`

Step-by-step explanation:

From the question we are told that:

Density of Material 1
`\rho_1=2000kg/m^3`

Density of Material 2
`\rho_2=6000kg/m^3`

Generally the equation for Average density is mathematically given by

`\rho_(avg)=frac{\rho _1+rho _2}{2}`

`\rho_(avg)=(2000+6000)/(2)`

`\rho_(avg)=4000kg/m^3`
