Question

The power needed to operate your body is about 100 watts. Suppose a human body (of typical mass) could run on fusion power and could convert 0.8 % of its mass into energy. Part A How much energy would be available through fusion?

Answer 1

Answer:

$5.04\times10^{16}$J  of energy is available through fusion .

Explanation:

let us consider weight of the human body on an average be 70 kg .

  since 0.8% of mass is used to convert into energy = $70\times \frac{0.8}{100} =0.56kg$

since according to einstein mass energy equation

 $E=MC^{2}$

 $E=0.56\times 9\times10^{16}\\ =5.04\times10^{16}J$
