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

`5.04*10^(16)`J of energy is available through fusion .

Step-by-step 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* (0.8)/(100) =0.56kg`

since according to einstein mass energy equation

`E=MC^(2)`

`E=0.56* 9*10^(16)\\ =5.04*10^(16)J`
