Hi I have an assignment due tomorrow, and have answered all the questions, I am just unsure about positive or negative flux
I know 5b) is positive, I think 6 is positive, and I'm guessing the other two are positive, but can anyone confirm?
And if I did get the sign wrong, would I have to redo the cross product, or can I just say at the end for instance that the flux is positive and change the sign from a negative to positive?
I got a negative answer, is that ok? or should I just say it's positive and change the sign to a positive one?
