I think its half the one of the water.
So 500 kg/m^3
If pressure is applied to a cube until its volume is halved, the density will increase by a factor of 2, since density is equal to mass divided by volume. As the volume decreases by half, the mass of the cube remains the same, leading to a doubling of density.
It will be half the mass of the whole cube.
Water is more dense than a half-dollar coin. The density of water is about 1 g/cm3, whereas the density of a half-dollar coin, usually made of a combination of metals like copper and nickel, is less than 1 g/cm3.
Yes, the wood would float in water because its density is less than that of water (1 gram per cubic centimeter). Objects with a density less than that of water will float, while objects with a density greater than that of water will sink.
Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
To determine the mass of one half of an aluminum (Al) cube, you first need to know the volume and density of aluminum. The density of aluminum is approximately 2.7 grams per cubic centimeter (g/cm³). If you have the volume of the entire cube, you can calculate its mass by multiplying the volume by the density, then divide that result by two to find the mass of half the cube. For example, if the cube has a volume of 100 cm³, the mass of one half would be 135 grams.
If pressure is applied to a cube until its volume is halved, the density will increase by a factor of 2, since density is equal to mass divided by volume. As the volume decreases by half, the mass of the cube remains the same, leading to a doubling of density.
The half dollar has the greatest density because it will sink, the water has more density than the pencil because the pencil will float.
It will be half the mass of the whole cube.
Water it depends how much water and many pencils. etc
half of a cube is called a tetrahedron
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
It could mean a cube tat has been cut into a half so that it is a cuboid. Or, it could mean a cube, each of whose sides is half a unit.
Water is more dense than a half-dollar coin. The density of water is about 1 g/cm3, whereas the density of a half-dollar coin, usually made of a combination of metals like copper and nickel, is less than 1 g/cm3.
No, it is not. It is half of it.
The volume of a cube is x3 where x is the side length. Therefore the volume of half a cube would be x3/2. For instance, if the side length of a cube was 2cm, the volume of one half would be 23/2 which comes out at 4cm3
fill a graduated cylinder half way up. then drop it in. see how much the water has rose. this is your density. this is also called water displacement
