Based on this, Individual electrons in graphene have almost no mass compared to the other particles.
The material graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice.
Electrons flowing through graphene can be scattered from impurities (such as foreign atoms in the lattice), from other electrons and from lattice vibrations known as phonons.
What happens to the electrons in graphene?
According to the researchers, such high values are a result of the photo thermoelectric effect. “It turns out that when you shine a light on graphene, the electrons in the material heat up, and remain hot, while the underlying carbon lattice remains cool,”
Why are electrons massless in graphene?
Yes, low energy electrons and holes in graphene can be thought of as massless because of the linear dispersion of the band structure near the K points.
This is an analogy to the relativistic energy dispersion E2=P2C2+M2C4, which becomes linear in momentum for m=0.

Answer : The hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.
Explanation :
As the organic compounds are classified into two categories that is acyclic (aliphatic) and cyclic (aromatic) compounds.
Acyclic compounds : It is an open chain compound with linear structure.
Cyclic compounds : It is a closed chain compound having a carbon ring structure.
Hydrocarbon : It is an organic compound that contains only hydrogen and the carbon atoms. They are of two types which are saturated hydrocarbon and unsaturated hydrocarbon.
Saturated hydrocarbon : These are the compounds which containing single bonds between the carbon-carbon atoms. In saturated compounds, there are more number of hydrogen bonded with the carbon atom.
Unsaturated hydrocarbon : These are the compounds which containing double and triple bonds between the carbon-carbon atoms. In unsaturated compounds, there are less number of hydrogen bonded with the carbon atom.
Hence, the hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.
An electric motor produces heat while running. The amount of heat is roughly equivalent to the amount of power delivered to the motor.
It depends on the weight and the high and the location of the object. I hop I helped. Have a great day
