Serena is mixing a material into a beaker filled with a liquid. She notices that the material seems to disappear into the liquid. What physical property of the material is Serena most likely observing? solubility conductivity magnetism density

The physical property of the material is Serena most likely observing is solubility.

Explanation:

Solubility is defined as the property of a substance to get dissolve in another substance. A small amount of substance is termed as solute and a substance in a larger amount is called a solvent.

Intermolecular interaction of solute particles with solvent particles results in the dissolving of a solute in the solvent.

Conductivity is the property of the substance to conduct heat, electric current, or sound through them.

magnetism is a physical phenomenon that arises due to the motion of electric current through a conductor resulting in the production of a magnetic field.

Density is a measure of the mass of a substance present in the unit volume of the substance.

So, when Serena observed the disappearance of a material into a beaker filled with liquid she is observing the property of solubility of that material.

Solubility

Explanation:

Material becomes soluble in solvent and disappears.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
