The starting materials in a nuclear change have a total mass of 2.3465 × 10–27 kg. After the change, the resulting materials have a mass of 2.3148 × 10–27 kg.
How much energy was released during the change?

Respuesta :

Answer:

The energy released during the change is [tex]2.853\times10^{-12}\ J[/tex].

Explanation:

Given that,

Total mass [tex]m =2.3465\times10^{-27}\ kg[/tex]

After change , the mass of resulting materials

[tex]m'=2.3148\times10^{-27}\ kg[/tex]

Using the Einstein's mass energy equation

[tex]E = mc^2[/tex]

The energy released during the change is given by

[tex]\Delta E= \Delta mc^2[/tex]

Where, [tex]\Delta m[/tex] is the change of mass in the process

c = speed of light

The change in mass

[tex]\Delta m=m-m'[/tex]

[tex]\Delta m=2.3465\times10^{-27}-2.3148\times10^{-27}[/tex]

[tex]\Delta m= 0.0317\times10^{-27}\ kg[/tex]

We substitute the value into the formula

[tex]\Delta E = 0.0317\times10^{-27}\times(3\times10^{8})^2[/tex]

[tex]\Delta E= 2.853\times10^{-12}\ J[/tex]

Hence, The energy released during the change is [tex]2.853\times10^{-12}\ J[/tex].
