Question

If one gram of matter could be completely converted into energy, the yield would be

A. 0.51 MeV.

B. 931 MeV.

C. 3 × 1013 J.

D. 9 × 1013 J.

E. 9 × 1016 J.

Answer 1

Energy,
`E=9* 10^(13)\ J`

Step-by-step explanation:

It is given that,

Mass of matter, m = 1 g = 0.001 Kg

If this matter is completely converted into energy, we need to find the yield. The mass of an object can be converted to energy as :

`E=mc^2`

c = speed of light

`E=0.001\ kg* (3* 10^8\ m/s)^2`

`E=9* 10^(13)\ J`

So, the energy yield will be
`9* 10^(13)\ J`. Hence, this is the required solution.
