To calculate the density, find the mass and the volume.
Mass divided by volume = Density.
Each substance has a different density.
Density is measured in g/cc (solids) or g/ml (liquids).
There is no such term. The regression (or correlation) coefficient changes as the sample size increases - towards its "true" value. There is no measure of association that is independent of sample size.
It means that the speed of light in that medium is the same as in vacuum. This is ALMOST the case for stuff like "air". If you measure closely enough, it is only true for vacuum, all other materials have an optical density > 1.
True. A balance IS used to measure the volume of things.
About that of water. This is true of most living things.
True
True.
False. The question says "... regardless of size and weight ...", but it is weight that is the force of gravitybetween the object and the earth. So when the weight is different, the force is different, by definition.
Hmmm... technically false. Density is mass/volume - it is an intrinsic property. Weight is subjective to the force of gravity, while density is not.
Graphing is used in measuring density. It plots the temperature and density as read, and gives the true density at standard conditions.
Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
The density of a textbook can vary based on its size, weight, and the materials used in its construction. On average, a standard textbook may have a density of around 0.7-1.2 grams per cubic centimeter.
Density can be defined that way, but it is more common to use another kind of density: mass per unit volume.
Any sample size of a particular substance will have the same density.
False it increases them!!!!
Yes, they can measure to the size of a tennis court.No, it is not. It is only about the size of a small hotel bathroom floor, not including the tub.
It depends on the size on the cup you are talking about and the weight of things in the cup but a cup is not a true measurement like ounces to pounds. You can weigh how many pounds with a balance.
