What subatomic particles have a mass of 0?
The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.
What is a Zeuthen-Segre invariant?
A Zeuthen-Segre invariant is an invariant of complex projective surfaces.
A chair has a mass 10 kilograms on Earth. What is the mass of the chair on Mercury?
A body's mass is invariant regardless of its position in space. Therefore, the chair's mass on Mercury will be identical to the chair's mass on Earth, that is 10 kilograms.
What is the mass of 25kg on the moon?
the mass is an invariant: so 25kg mass would still be 25kg mass where ever it was. the force a 25kg mass exerts would change, as the force is a variant that would be altered by the lower gravitational strength of the moon.
WHAT According Einstein is the relativistic mass of light?
Any object has two masses associated.What is sometimes called the rest mass, or invariant mass, for the photon (piece of light), is zero. Its relativistic mass is equal to its energy divided by c squared.
The difference between mass and rest mass?
"Mass" is often understood to mean "rest mass", at least in more advanced treatments of the topic. This is because it is the invariant mass - the "rest mass" is the same for all observers. However, "mass" might also refer to the relativistic mass - the mass, increased due to a high speed.
What is a sentence using the word mass?
What is the mass of that compound? We calculated the mass of the sample.
What percentage of the speed of light is required to double the moving object's mass?
Seems simple but it is a bit more complicated than that. The Relativistic Mass is only energy, not Mass. The "Invariant Mass", also known as Rest Mass, does not change. See: http://math.ucr.edu/home/baez/physics/Relativity/SR/mass.html
What substance that is calculated by its mass by volume?
No substance is calculated that way. Mass per unit volume is called the density of a substance or object, which is a property or unit of measure of a substance.
What is a protons mass calculated by?
They are calculated by atomic mass units (amu) proton-1amu neutron-1amu electron-0amu
What is density calculated by?
Density is calculated by dividing the mass and volume of an object.
What the difference between mass and weight and how they pertain to gravity?
Mass is the quantitiy of matter. But weight is the force of pull on the mass due to gravity. So mass is invariant where as weight depends on the gravity. If acceleration due to gravity is zero, then weight too becomes zero. So in free space mass exists but weight vanishes.
