Biology

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.

<span>Vagus Let's look at the list of cranial nerves to see what they do 0. Terminal - Animal tests indicate this nerve is involved in detecting pheromones. I. Olfactory - Handles the sense of smell. II. Optic - Handles the transmission of visual signals. III. Oculomotor - Handles the movement of your eyes. IV. Trochlear - More eye movement. V. Trigeminal - Allows you to sense touch on your face and chew your food. VI. Abducens - More involvement with the eyes. VII. Facial - The name says it all. VIII. Vestibulocochlear - Sense of hearing and balance using the inner ear. IX. Glossopharyngeal - Taste and some motor movement. X.
