Average Density is the total mass of an object divided by the total volume.
bouyancy density
Rock density has no direct affect on war.
The moon's average density is about the same as the density of mantle of the Earth.
The density is lower.
affect turtles
It affects almost like density.
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
bouyancy density
Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
It's difficult to tell what you are asking. If the question is concerned with the bouyancy of the object, it will sink if it first displaces its volume of water, or will float if it first displaces its weight in water. Since density is mass per unit volume, objects with an average density greater than water will sink.
because boaties can floatie
Buoyancy is the ability to float, so if the density is high, it'll hold up something. (see? FLOATING. BUOYANCY.)
more salt means more density so more buoyancy.
An object will sink in a fluid medium if its density is greater than that of the medium.
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
Divers use substances with high density (ie. lead) to help them sink, and substances with low density (ie. air) to help them float. That way they control their bouyancy.
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
