A black hole
This scenario would describe a theoretical point-like object known as a singularity, such as a black hole. In a black hole, the mass is compressed to an infinitely small point with extremely high density, resulting in gravitational effects that warp spacetime around it. The singularity is thought to be hidden by the event horizon of the black hole, beyond which no information can escape.
This object has a density of about 18.84 g/mL
Not enough information. To get the density, you need to divide the mass by the volume, but there is no way of knowing the volume of an object just by having one of its lengths.
The density of the object is calculated by dividing its mass by its volume. In this case, the density would be 0.32 g/cm³ (8.0 g / 25 cm³).
The density of the object is calculated by dividing the mass by the volume. In this case, the density would be 17g/3cm^3, which equals 5.67 g/cm^3.
density = mass/volume = 6/32 = 0.1875g/cm3
Impossible to tell, since "12 centimeters squared" is not a volume. It could be anything between infinity and zero density. If you meant 12 cm3, then the density is about 2.1 gm/cm3.
The density of a liquid affects the buoyancy of an object by determining whether the object will float or sink in that liquid. If the density of an object is greater than the density of the liquid, the object will sink. If the density of the object is less than the density of the liquid, the object will float.
An object will float in a fluid if its density is less than the fluid's density. If the object's density is greater than the fluid's density, the object will sink. If the object's density is equal to the fluid's density, it will be suspended at a specific depth.
Density = Mass/Volume = 2.2g/34cm3 = 0.0647 g/cm3 approx.
To predict the density of a floating object, you can compare the density of the object to the density of the fluid it is floating in. For an object to float, its density must be less than the density of the fluid. You can calculate the density of the object by dividing its mass by its volume.
The weight of an object at infinity would be zero since there is no gravitational force acting on it at that distance.
