Question

Do I have the correct solutions when expressing the above in a and b?

Answer 1

We have

`1.2\text{ }*10^(44)\text{ Joules}`

We need to put this quantity in

a. Kilojoules

we have the next equivalence to convert J to KJ

1000 joules = 1 kilojoule

`(1.2*10^(44))/(1*10^3)=1.2*10^(44-3)=1.2*10^(41)KJ`

b. nano joules

we have the next equivalence to convert J to nJ

1J = 1000000000 nJ= 1x10^9 nJ

`(1.2*10^(44))(1*10^9)=1.2*10^(53)nJ`
