Ajar contains 30 ml of glycerin (mass=37.8 g) and 60 ml of corn syrup (mass=82.8 g). which liquid is on the top layer? explain your answer.

Glycerin

Explanation:

Applying the concept of density, the less dense material stays at the top while the more dense material stays below in the glass.

Density (ρ) = mass / volume

Density of glycerin = 37.8 / 30*10⁻³ = 1260g/l

denisty of corn = 82.8 / 60* 10⁻³ = 1380g/l

from the above calculation, it shows that maize has the highest density and would stay below glycerin in the jar.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
