Hi I am very new to physics and am not advanced at all, but can someone please help me answer the attached question? I mean it gives the answer too. I'm just not sure if I fully understand the answer yet. My comments are highlighted in red.
You're misunderstanding the units. If there are some J from a kg, the units are J/kg. If there are some J released every second, the units are J/s. If you are asked how many kg do you need to convert every second, the units are kg/s.
Now, how do you get kg/s from J/kg and J/s? You divide them, of course.

jebus197 you posted this on PHF here. It seems you didn't quite understand what the other members were trying to say. That's fine. But please tell us what exactly is your question at this point? What did you not understand from the posts at PHF? Don't make MHF redo all the work done already.
