Question

prove that e=mc^2.....fast​

Answer 1

E= MC² MEANS ENERGY = MASS ²


This formula states that the equivalent energy (E) can be calculated as the mass (m) multiplied by the speed of light (c = ~3×108 m/s) squared. Similarly, anything having energy exhibits a corresponding mass m given by its energy Edivided by the speed of light squared c2. Because the speed of light is a very large number in everyday units, the formula implies that even an everyday object at rest with a modest amount of mass has a very large amount of energy intrinsicall.



E=MC² is the formula of Albert Einstein theory of general relativity . from this , u can make time machine but now days , it is not completely correct . becoz to make time machine , u need very very high power as speed of light , but we have not enough power to go at speed of light and the second point is that if we go at speed of light , our body is heated up and make radiation as the result, we die or spoil

so, it's not completely true

Hope it's help u.....

Answer 2

According to Plank’s Equation:

E = hf

E = h(c/λ ) as c=fλ

E = Pc as momentum= h/λ

E = (mc)c as momentum= mv in this case v=c

Finally,

E = mc^2
