In a nuclear fusion reaction, the loss in mass is 0.3%. Energy released in the fusion of 1 kg mass will be :​

Answer 1

In a nuclear fusion reaction, the loss in mass is 0.3%. Energy released in the fusion of 1 kg mass will be 2.7 × 10¹⁴ Joule

Step-by-step explanation:

Given mass = 1 kg

Mass lost = 0.3% of 1 kg

               $=1\times\frac{0.3}{100}$

               $=3\times 10^{-3}$ kg

We know that energy released

$\boxed{E=\Delta mc^2}$

Where c is the velocity of light $=3\times 10^8$ m/s

Therefore, the energy released

$E=3\times 10^{-3}\times(3\times10^8)^2$

$=3\times 9\times 10^{13}$ Joule

$=2.7\times 10^{14}$ Joule

Hope this answer is helpful.

Answer 2

Answer:

$\huge\boxed{\dag\sf\red{ANSWER}\dag}$

$\huge\bold\blue{Given:}$

Mass lost in fusion reaction ∆m =

0.3%

$\huge\bold\blue{Therefore,}$

Loss in mass in fusion of 1 kg mass

=0.3/100*1kg

=0.003kg

Energy released E=(∆m)c²

=0.003*(3*10 8)²

=2.7*10¹⁴ joule.

hope its helpfull..
