What determines the mass of objects that have equal volume?
Density. This is quantified as a mass over a volume, so if you know the volume, the density will allow you to determine the mass of an object. Density equals mass divided by volume so mass is equal to density multiplied by volume.
How is the mass of an object different from its density?
Density is equal to the mass divided by the volume.
An object's density is equal to its mass divided by its what?
Density is mass divided by volume
Is it true that momentum is not equal to the mass of an object divided by its velocity?
That is true because momentum is mass times velocity
If 90 percent of an object is floating below water what is its density?
Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.
Does cutting an object into equal halves affect its mass?
If the object has uniform density throughout, and it is separated into two parts of equal volume, the two parts will also have equal mass, and if it is separated into two parts of equal mass, the two parts will also have equal volume. If the density of the object is not uniform, and the object is separated into two parts of equal volume but unequal average densities, the part with the higher average density has more mass. In any case, the sum of the masses of the two halves is equal to the mass of the original object. That is the law of conservation of matter. The only exception is when energy is produced by the combining (fusion) or separating (fission) of matter. For example, in the core of the sun, hydrogen atoms are pressed together to form helium atoms and energy. The mass of helium created by combining one gram of hydrogen with another gram of hydrogen is less than two grams; the mass lost in the fusion is converted into radiant light and heat.
How does the mass of an object compare to the mass of its parts?
the mass is the same because think about it you made the object from its parts so they would be the same

What does equal parts by mass mean?
it means to have and equal part of mass
What You weigh the mass of an object you then cut the object in two halfs and weigh the total mass of the two halves is what to the mass of the original object?
it is equal to the mass of the original object
What does it mean to know the mass of an object?
it means that you found the mass of an object.
What determines the mass of objects that have equal volume?
Density. This is quantified as a mass over a volume, so if you know the volume, the density will allow you to determine the mass of an object. Density equals mass divided by volume so mass is equal to density multiplied by volume.
Is every object mass equal to weight?
No, they are almost never equal.
How an object float in a liquid with illustration?
When the displaced fluid has a mass equal or greater than the mass of an object placed in the fluid, the object will float.
How is density different from the mass of an object?
Density is equal to the mass divided by the volume.
