Answer:

it means that the mass of 1 cm^3 of the metal is 8.9 grams.

The density is used to approximate how heavy and object is going to be. The mass of an object with known density and volume can be calculated using;

Mass = density × volume

Density is used to determine whether an object would float or sink in water of other substances.

Density is also considered in the selection of materials for construction, fabrications and manufacturing of products

Explanation:

Density is the measure of compactness of a substance. It is simply the mass of a unit volume of a substance.

Density = mass/volume

If the desinty of a metal is 8.9g/cm^3, it means that the mass of 1 cm^3 of the metal is 8.9 grams.

That means that the mass of a unit volume (1cm^3) of the metal is 8.9 g.

The density is used to approximate how heavy and object is going to be. The mass of an object with known density and volume can be calculated using;

Mass = density × volume

Density is used to determine whether an object would float or sink in water of other substances.

Answer:

It means that in every cubic centimeter volume of the metal, there is 8.9 grams mass of the metal.

Explanation:

It means that the degree of compaction of the atoms of the metal is 8.9 g/cm3.

It also means that in every cubic centimeter volume of the metal, there is 8.9 grams mass of the metal.

This information (density) will help us to understand how dense the the metal is, whether it will float or sink when immersed in a certain fluid.

Example, this metal will sink when it is immersed in water, because density of water is 1g/cm3, which is less than the density of the metal.

Also, this metal will float when immersed in a fluid like heavy crude oil, whose density is great than 8.9g/cm3.

When visiting some countries, you may see a person balancing a load on the head. Explain why the center of mass of the load need
Vinvika [58]

Explanation:

If the center of the load is directly above the vertebrae, there is no torque in the system. This is a good thing so that the vertebrae are not put out of alignment over time. (Of course, this still doesn't prevent compression of the vertebrae over time, which is a possibility.)
