If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.
The units are the same for any object (for example, kilogram/m3). What changes is the methods you can use to measure it.
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
It is length * breadth * height.
Well it depends on the density of the object and the density of the liquid that it is placed in. The object produces a buoyant force that lifts it to the surface of the liquid.
Density is equal to the mass of the substance divided by its volume: D (density) = M (mass) / V (volume), so the density equals 94/12= 7.833...
density=mass/volume Thtas how dez equations are found.
