How do you find volume without density and mass?
A simple method based on the moment of forces and Archimedes’ principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms.
What is the formula for density without mass?
Originally Answered: How do we find the volume of an object without knowing neither the density nor the mass? The formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).
Can you have volume without mass?
Based on the latest breakthroughs in particle physics, the answer is a plain NO – it’s not possible for a massive particle to have no volume. In fact, it is NOT possible for any particle, whether massive or massless, to have zero volume. Particles that do not interact are massless, those that do exhibits mass.
Can you have density without mass?
It is possible to find the density of a substance with- out knowing its mass. Using a standard substance of known mass and volume, the density of a sub- stance can be found using the principle of moment of forces.
How do you find the density of the Earth?
The density of Earth is calculated by dividing the planet’s mass by its volume, then simplifying from kg/km to g/cm cubed.
What is the density of Earth in KG?
5515 kg.m−3
Why is Earth’s density so large?
Due to the power of its own gravitation, Earth is compressed by a few percent over what its density would have been without so much mass.
Does Mercury have a higher density than water?
Mercury is a very dense, heavy, silver-white metal that is a liquid at room temperature. Mercury has a density of 13.5 g/mL, which is about 13.5 times denser than water (1.0 g/mL), so a small amount of mercury like this feels unexpectedly heavy.
Is wood more dense than water?
Wood is less dense than water. This means that particles of water are more close together than particles of wood. And so the kinetic energy of water particles should be less than the kinetic energy of wood particles.
What is Mercury’s density?
5.43 g/cm³
