The center of mass of a sphere is its geometric center.
It depends on the information you have. You could put the sphere on a flat surface and lower a horizontal plane onto it so that it just touches the top of the sphere. The distance between the flat surface and the horizontal plane is the sphere's diameter; the radius is half that. Or you could measure its volume by measuring the amount of fluid (water) that it displaces in a measuring container or the overflow from any full container. Then use the formula V = 4/3*pi*R3 to work out the radius. If you knew the density of the material of the sphere, you could measure its mass and work out its volume that way.
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
Since gold is 19.32 grams per ml and water is 1 gram per ml they both have the same mass
By studying the displacement of water caused by pure gold and silver of the same mass, he proved that the gold crown was not of pure gold as claimed by the jeweller.
The mass is 1 367 g.
The volume of the rock is the amount of water it displaces, 250ml. Considering that 1ml of water has a mass of 1 mg, the mass of the rock is 5.63 x 250gm = 1,407.5mg.
The mass of an object does not directly affect the amount of water it displaces. The volume of water displaced is determined by the volume of the object that is submerged in the water, regardless of its mass. Archimedes' principle states that the buoyant force (or weight of the water displaced) is equal to the weight of the object, not its mass.
Determine its volume by how much water it displaces, then divide mass by volume
Because we take the water's space so it needs to rise. It was discovered by Aristotle when he fulled his bath full of water and it overflowed.
Negative buoyancy occurs when an object displaces less than its mass of whatever its not floating in. A liter of water has a mass of 1kg, but displaces less than 10g of air, so water sinks in air.
Yes, an object that floats displaces water equal to its own weight. This is known as Archimedes' principle.
Float
If the object floats you can calculate its mass by the amount of water it displaces and its size. If it doesn't float i am not sure.
No. That only tells you the diver's volume.
the mass decreases as the wax burns so it displaces less water
A 1 pound fish displaces approximately 1 pint (or 0.47 liters) of water. This is known as the Archimedes' principle, which states that an object submerged in a fluid is buoyed up by a force equal to the weight of the fluid it displaces.
