The distance between the sun will exhaust all of its energy in about ten billion years. By that time, it will have radiated about 1.2x10^-44(joules) of energy. Express this amount of energy in kilojoules

Respuesta :

Answer:  [tex]1.2(10)^{-47} kJ[/tex]

Explanation:

1 Joule ([tex]1kJ[/tex]) is equivalent to [tex]10^{3}J[/tex]. So, we have to make the conversion:

Joules   KiloJoules

[tex]1kJ[/tex] ---- [tex]10^{3}J[/tex]

? ----------[tex]1.2(10)^{-44}J[/tex]

[tex]1.2(10)^{-44}J \frac{1kJ}{10^{3}J}=1.2(10)^{-47} kJ[/tex]
