How much energy is produced when the sun

adell [148]

Answer:

$E=1.53\times 10^{17}\ J$

Explanation:

We need to find the energy produced when Sun converts 1.7 kg of mass into energy. Einstein's mass energy relation is given by :

$E=mc^2$

c is speed of light

$E=1.7\times (3\times 10^8)^2\\\\E=1.53\times 10^{17}\ J$

So, energy produced is $1.53\times 10^{17}\ J$ .

13. What happens when a protein is deNtured?

soldier1979 [14.2K]

Denatured proteins have a looser, more random structure; most are insoluble.</em>
