Okay I have received my hsc results and I just want to say that official's estimate of 99.60+ was right. Although there were a few disappointments in my results for some subjects I am relatively pleased. Thanks to all the people who gave me an estimate. By the way I was able to a band 6 in...

Hey guys so then 12.d is right?

How was the option? What did people get for the equilibrium constant? I got 2450... a little different from other people.

I just edited the post ^ I actually got mg/kg. Thanks.

I got something like 0.17mg/L for the concentration from the graph. My final result after calculations was something like 0.23mg/kg which is smaller than 0.5mg/kg so it is safe to eat.

Hey guys I think 7 is D because bromothymol blue is green when neutral.

Hey some1thing how did you go for the rest of the test?

This feeling is horrible... im looking at 2-3 mc questions wrong...

Did i get 19 for my mc?

Oh no they were talking about force... i thought it was gpe...

Change in gpe is always positive. Induced emf is in opposite direction. Lenz's law. I think the back emf has to be smaller because there needs to be a constant supply emf for the motor to turn in a constant rotation. For gpe the radius is not squared...

This is what I got 1. D 2. A 3. C 4. C 5. C 6. C 7. B 8. A 9. B 10. D 11. D- this one was hard 12. A 13. B 14. D 15. D- i think the wording was a little off 16. A 17. B 18. A 19. D 20. B

Re: General Thoughts: Physics Umm wasnt emf graph d because induced emf is opposite... or something like that

I talked about the variation in the acceleration due to gravity and lightly touched on the vertical and horizontal motions being independent...

Post your answers.

I said n=4,8,12... would that also be marked right?? I didn't specifically say that n was a multiple of 4...

nucgaek I then said that n=4,8,12... would that also be marked right?? I didn't specifically say that n was a multiple of 4...

I got that too chriss95. For the last part of q11, I said that since n has to be an integer, r has be to divisible by 3. Since it was n=4r/3.

^ I was told by my teacher that you will be marked wrong for cii) if you got i) wrong...
