we use it by making things strong
Mass = Density -------- volume
The principle of density was discovered by Archimedes. To calculate density, we use the equation Density = mass/volume.
density= mass/volume
The density of a substance can be measured in a laboratory.
Females use the concept of density during pregnancy. They gain weight, ie density, and inside them a growing life occurs. Humans also use density during swimming and water play to remain buoyant.
Let's test the density of that wallboard with this two by four.
Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.
If the object's density is greater than the density of the liquid in which it is placed, it will sink. If the density is less, it will float. You can use math to calculate the density, if you know an object's mass and volume. Density is defined as mass divided by volume.
Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = mass / volume. The SI unit for density is kg/m^3.
They would use density to measure the volume of a substance :)
That's very nice of you to offer but I have no need of a sentence with density in it.
