No, there is no formal procedure for establishing a legal residence in Massachusetts. Voter registration, automobile registration, a driver's license, the appearance of a person's name on a city or town street list, and rent, utility, mortgage or telephone bills normally provide tangible proof of residence.
You weight it.
The amount of mass in a certain volume of matter is called density. Density is calculated by dividing the mass of an object by its volume, and it represents how much mass is contained in a specific amount of space.
mass = volume X density
Mass.
The amount of matter (mass) in a certain amount of space (Volume).
It has like more dense
Black Holes are created when stars above a certain mass start collapsing in on themselves. They're mass affects space time and they become a small point in space with an unimaginably large amount of gravity.
Mass per unit volume is the object's "Density".
The massof an object is how much matter there is in the object.
Jupiter did not become a star because it lacks the mass needed to sustain nuclear fusion in its core. Stars need a certain amount of mass to generate enough pressure and heat for nuclear fusion to occur, and Jupiter's mass is not sufficient for this process to take place.
Density is the amount of mass in a certain unit volume of a substance (Density equals mass divided by volume).
The amount of mass an object has in a certain volume is known as its density. Density is calculated by dividing the mass of the object by its volume. It is typically measured in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
