Question

Explain About Mass–energy equivalence(E=mc2)

Answer 1

Answer:

About mass energy

Explanation:

It was discovered by Albert Einstein.

according to enstiens mass energy theorem that,

E=mc square

E=energy of the electron.

m=mass

c=constant

=3×10 power8 m/second or

3×10 power 10 cm/second

Answer 2

${\bold{\blue{\underline{\red{A}\pink{ns}\green{we}\purple{r:-}}}}}$

➝ Albert Einstein said that mass and energy are equivalent and are related by the equation:-

⤇ E = mc²

• E is the amount of energy.

• M is the mass.

• C is the speed of light (in vacuum)

⤇The speed of light is very very large so,an extremely large amount of energy is produced even if a small mass gets destroyed.

⤇The destruction of mass happens in nuclear reactions like nuclear fission and fusion with the liberation of tremendous amount of energy.

⤇In the mass energy equation if we put the mass in (kg) and the speed of light in (m/s) then,then energy will come in joules(J).
