A12-kg piece of metal displaces 1.6 l of water when submerged. part a find its density. express your answer to two significant figures and include the appropriate units.

ρ = 7500 kg/m³

Explanation:

Given that

mass ,m = 12 kg

Displace volume ,V= 1.6 L

We know that

1000 m ³ = 1 L

Therefore V= 0.0016 m ³

When metal piece is fully submerged

We know that

mass = Density x volume

Now by putting the values in the above equation

ρ = 7500 kg/m³

Therefore the density of the metal piece will be  7500 kg/m³.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
