Its the same, even though the mass is smaller, so is the volume, there for the mass to volume ratio stays the same when you cut it in half.
Diedrick Crayon has written: 'The return of the Half Moon'
The diameter of a crayon is 5/16 of an inch.
It's identical. (assuming that the object is homogeneous)
5 gramme
A gram is a unit of mass. A litre is a unit of capacity. Without a measure of density to compare, the two units are incompatible.
The density of each half remains the same as the original density of the bar. Cutting the aluminum bar in half does not change the density of the material, as density is an intrinsic property of the material.
before or after the three year old eats half of it?
The density of something is the mass divided by the volume, so if you cut the item in half, it will not change the density at all. Instead, the two halves of the item will have the same density.
Whole Whole Half Whole Whole Whole Half
You can determine whether a key is major or minor by looking at the pattern of whole and half steps in the scale. In a major key, the pattern is whole, whole, half, whole, whole, whole, half. In a minor key, the pattern is whole, half, whole, whole, half, whole, whole.
If you cut a metal in half, each half will have the same density as the original metal, so the density of each half will still be 8.4. The density of a material does not change when you cut it into pieces.
That's not true at all. The whole idea of density is that it doesn't depend on the size of the sample; big samples and small samples of the same substance have the same density. If the whole object and a piece of it have different densities, then you can bet the composition of the piece is different from the composition of the whole thing. Example: The whole object ... a rock glued to a surfboard ... has low density and floats. One piece of it ... the rock ... has high density and sinks. (Another piece ... the surfboard ... is even less dense than the complete object, and floats even better.)
