Answer:
<em>The density of rock = 3.37 g/cm³</em>
Explanation:
Density: Density can be defined as the ratio of the mass of a body to the volume. The S.I unit of density is kg/m³. It can be expressed mathematically as ,
D = M/V............................................... Equation 1
Where D = density of the body, M = mass of the body, V = volume of the body.
From Archimedes' principle, a body will displace a volume of water equal to its volume.
Therefore, Volume of the object = volume of water displaced
<em>Given: M = 300 g, V = volume of water displace = 89.0 cm³.</em>
<em>Substituting these values into equation 1</em>
<em>D = 300/89</em>
<em>D = 3.37 g/cm³</em>
<em>The density of rock = 3.37 g/cm³</em>
The sun gets its power from nuclear fusion. In the suns core.
