6.6(recurring)% for the percentage of people over 100 in professor yakner's study.

Momentum - 0

Velocity - I got sqrt(75,000) - pretty sure that's right

Possibly an A?

The grade boundaries are quite low for the ideas in context paper. :smile:

I said something like the energy in the blister process was to make the sulfur thing hot and then the air blasting and in electrolysis lots of electricity was used?

Although maybe I didn't answer the question correctly...

Eventhough the exam seemed easy, I think the grade boundaries will be low because lots of people in my school were getting different answers for some questions (apart from the physics ones which everyone got the same).

Yeah sorry, thats the one

sqrt((112,500 x 2) / 3) = sqrt(75000)

sqrt((112,500 x 2) / mass)

Ahh I was worrying that I had it wrong there. :P

It was a fairly difficult paper, especially the one on C5 (Chemicals of the natural environment). B6 and P4 were relatively okay. Looking at these posts though, I think I got most of them wrong. It wasn't something I could revise too much on, since I had my History exam this morning (which I felt was more important). Oh well, even if I'll do badly on this one, I'll revise super hard for the last two exams to balance the grade out.
