Question

Physics question about density

Answer 1

The answer is option 4.

Step-by-step explanation:

Firstly, you have to convert the mass of tea bagto kilogram as the question wants the unit in kg/m³.

`1000g = 1kg`

`100g = 1kg / 10`

`100g = 0.1kg`

So the mass of tea bag is 0.1 kg. Next you have to use density formula ρ = mass/volume. Then you have to substitute the values into the formula :

`ρ = (mass)/(volume)`

Let mass = 0.1kg,

Let volume = 0.025m³,

`ρ = (0.1)/(0.025)`

`ρ = 4kg \: per \: {m}^(3)`

Answer 2

So the right answer is 4kg/m^3.
