Answer:
If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.
Explanation:
Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.
If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:
ρ = m/V
Therefore, according to the mass and volume of the rock
ρ = 12 grs / 2 cm³
<em>ρ = 6 grs/cm³
</em>
Being the density of the rock equal to 6 gr/cm³.

Answer:
The first yellow fever outbreaks in the United States occurred in late 1690s. Nearly 100 years later, in the late summer of 1793, refugees from a yellow fever epidemic in the Caribbean fled to Philadelphia. Within weeks, people throughout the city were experiencing symptoms.
