Ineed the answer now in the equation e=mc2, what does “c” stand for? carbon speed of light mass star age

Speed of light

Explanation:

The famous Einstein's equation is:

where

E is the energy

m is the mass

is the speed of light

In this equation, Einstein summarized the following fact: mass can be converted into energy, and the amount of energy released in such a process is given by the equation.

An example of application of this equation is the nuclear fusion process. In a nuclear fusion, two lighter nuclei combine into a heavier nucleus. However, the mass of the heavier nucleus is slightly less than the sum of the masses of the two original nuclei: some of the mass of the original nuclei has been converted into energy, accorging to the previous equation.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
