I think when I did this experiment I changed the variables I and B . The equipment set up was as follows: When changing the variable I 1. When you turn the power supply on, adjust the rheostat so that it reads around 1A. Then turn the power supply off. 2. Before you turn the power...

Depends what textbook you used but to be honest, most textbooks provide more than sufficient information for the exam. I personally found Biology in Focus the most helpful - it has almost all the information you really need and would definitely prepare you well for the exam. I would recommend...

If you're equally skilled in both (which I assume means that you'll get similar marks), then it would probably be better to pick the better scaling subject to maximise your ATAR. Just remember that scaling for each subject differs each year and depends on how the NSW cohort in that subject...

I got 221.35 A I guess this was my working. I don't know if you need it but I'll just put it here $ Use Ampere's Force Law $ F = \frac {kI_1I_2l}{d} $ However, both wires are connected to the same car battery so the currents should be the same. Therefore, we can rewrite the equation as...

Yeah as fan96 said, the catalyst used is sulfuric acid for both the hydration of ethylene and the dehydration of ethanol. Dehydrating ethanol to ethylene requires concentrated sulfuric acid as a catalyst. Hydrating ethylene to ethanol requires dilute sulfuric acid as a catalyst. A nice way...

I think that just means 'Real Numbers'. It's mainly just used as a restriction or as some extra info to a question I think such as saying that 'x' is/can only a real number.

To be honest, if you can come first in all your subjects in Year 12, your cohort at your current school won't drag you down in terms of HSC marks and ATAR - the only way they might 'drag you down' could possibly be through a lack of academic motivation within the grade whereas if you go to a...

Ah yep that's true - silly mistake from me haha haven't done 4U in a while rip xD. Thanks for clearing that up!

Eek I haven't done 4U in a while so I might be a bit rusty but this is what I got - hopefully it's right. https://i.imgur.com/a8xeaNY.jpg Essentially, since it's an isosceles triangle with z3 as a right angle, the remaining angles would be 45 degrees. Therefore, I think you can just manipulate...

Haha not really an idol anime but I really liked both seasons of K-On! I plan to watch Love Live soon though.

I would recommend sticking to Advanced. Although Standard English scales similar to Advanced English, it aligns rather poorly from what I've heard. I think this means that scoring a Band 6 in Standard will be much harder than scoring a Band 6 in Advanced. To put it into context, according to...

Oh nice haha thanks for letting me know! Yeah I thought the movie was great when I watched it in the cinemas - it's actually one of my favourite anime movies alongside 'A Silent Voice'.

I'm not fully sure of this but it might be because although you're increasing the formation of H2CO3, you're also diluting the solution at the same which I think decreases the overall concentration of aqueous stuff. So in essence, I don't think the increase in H2CO3 becomes very noticeable (in...

Anyone here have a favourite series? Idk but I really liked No Game No Life.

Depends on what you think is more interesting. Economics does usually scale a bit better than Biology but I would recommend picking something that you would enjoy rather than scaling since you'll be more motivated to study the more enjoyable subject and probably do better. Biology is heavy on...

If possible, try to stick with English (Advanced). I've heard that it doesn't align particularly well (although I'm not fully sure of this). I did all three sciences and I will have to admit, the workload is kinda a lot - however, some (but not a lot) of concepts in Biology and Chemistry...

If you don't want to get affected by moderation at all, I guess you'll have to be rank 1. However, if you're ranked like 2nd or 3rd, then you'll reduce the effects of moderation if you keep the gap between the person who's first relatively small. Remember that moderation not only counts your...

I just had a walk around the school or just drank some tea or water. If your school doesn't let you leave the library then maybe just walk around the library or talk to the teachers there for 5 minutes lol.

Your English and Legal rank look really strong so if you can capitalise upon that over the year you're bound to do really well on those subjects. First term assessments don't really mean much in terms of weighting so don't worry about that Ancient History mark. As long as you smash your...

Idk I play basketball but I like to watch soccer (i.e. football).
