Question

define :-

$e = {mc}^{2}$


points achhe see Dena English me

Answer 1

Explanation:

1.formula state that energy is equal to the product of mass and velocity square

2.it means energy is directly proportional to the mass

3.it also stated that energy is directly proportional to the velocity square

Answer 2

SOLUTION.

When somebody ask you to change the mass of the particular thing than you replied "how it's a constant quantity?" but actually it's not.

Just think of many nuclear reaction In which mass of the reactant is not same as the mass of the product.

So it's mean that mass gets destroy in these reactions. But actually "mass can not be created nor be destroyed it can convert from one form to other."

Now another question arises that if mass can be convertible than "how we convert the mass?" and to whom we convert it.

ANSWER OF THIS QUESTION IS ENERGY.

THAT is the reason behind lot of energy emitted during nuclear reaction.

Mass difference between reactants and products is converted in to heat energy and the relation between energy and mass can be given by Einstein's formula.

$E = m {c}^{2}$

where c is speed of light

m is the mass DIFFERENCE

E is the energy emitted.
