Question

❤️ HELLO ❤️

Calculate the amount of energy released in MeV due to a loss of mass of 1 kg.

thanks.....​

Answer 1

We shall use the formula

E = mc²

Therefore energy released due to loss of mass of 1kg will be

= 1×(3×10⁸)²

= 9 × 10¹⁸ J

= 5.61735841e+13 MeV

where c is the speed of light i.e. 3 × 10⁸ m/s

Answer 2

Explanation:

According to the famous equation of mass-energy conversion:

E=mC^2

Where,

E= energy released or absorbed during reaction

m= mass of particle

C= speed of light or photons= 3*10^8 m/sec

So, using this formulae,

Energy released= [{1*10^(-3)} * (3* 10^8)^2] joules = 9*10^13 joules = 90 TJ.

Basically this energy-mass conversion equation is used in such kind of calculations throughout.

Hope this might answer your doubts.

Thanks and regards.
