An object in space having a volume that is approaching zero and density approaching infinity?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
Yes.
density
Density is based off mass and volume, not weight and volume. Weight is a measurement of gravity, and changes based on strong the pull of gravity is in the area. Mass is a measurement of the amount of matter in an object, and does not change based on the pull of gravity. Density is Mass/Volume. Volume is a measure of how much space an object occupies. The more condensed matter is, the higher its density.
Gravity or gravitation. The larger and (most importantly) more dense the object - the higher (or greater) the gravity. So gravity is a function of mass (which takes both density and size into account - since something which is very large but has low density) can have a much lower mass than something which is tiny but has a very high density. Rotation (spinning) and electrical charge can also play a significant role in determing the gravity of any object.
A black hole
osmium has the highest density.
This object has a density of about 18.84 g/mL
Density is mass/volume. So the density of this object is 5/25 = 0.32 gram/cubic cm.
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.
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.
It doesn't - the object will never achieve the speed of light, since an infinite mass is not possible (it would require infinite energy). This only describes a tendency: as the object gets closer and closer to the speed of light, so, too, will its mass increase more and more, approaching infinity - this means there is no upper limit to the mass as the object approaches the speed of light.
Hi dear, it is enough to draw incident rays parallel to principal axis. That ensures that the object is at infinity and no need to draw an object at all.
An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.
Density = Mass/Volume = 2.2g/34cm3 = 0.0647 g/cm3 approx.
density of the object < density of the fluid
