Can someone (FizzyCyst pls help) explain why the answer here is C. I would have thought that it'd be D as high resistance would mean more heat given off due to resistive heating/friction.

I'm a little confused as to what indicators are used for what titrations. Wikipedia tells me: Strong Acid, Strong Base: Phenolphthalein Strong Acid, Weak Base: Methyl Orange Weak Acid, Strong Base: Bromothymol Blue However other sources are giving conflicting results and after coming...

Okay so came across this Integration question from Cambridge in class and nobody knew what we were doing after a while (even the teacher). The first and second bit of the question were fine but that last bit where you have the factorials is what we couldn't get to. The solution in Cambridge...

Okay so I just want to confirm/clear up something. I have read different sources and some say different things about the forces experienced by each end of the coil during the motor effect. Source 1: Each end of the coil will experience a force which varies from zero, when the plane of the coil...

How do you get rid of them? No seriously, in my first assessments, I lost quite a few marks to the stupidest mistakes possible. Not really for sciences and english, since its mostly learnt content, but for mathematics exams where you have to do working out. I am the king of sillies. Pretty sure...

Does anybody have a Cambridge Checkpoints book? How is it? Is it the same compared to Success One past paper books or is it different in some way? I need to buy a past papers book and wanted to know which one would be better for Biology, Physics and Chem.

We've covered complex numbers and started conics and I was wondering what people think the hardest topic in 4U Maths is? What should i not be looking forward to? :P Thanks!

Our first assessment at school for Chemistry is a second-hand investigation presentation on dot point 2.6 - "Use available evidence to gather and present data from secondary sources and analyse progress in the development and use of a named biopolymer. This analysis should name the specific...

Okay well the thing is that at the moment, I am doing Advanced English, 4U Maths, Physics, Chem and Bio. I enjoy studying the sciences and believe I can get relatively good marks in all of them. But with 4 unit maths, this leaves me with a lot of work to do, considering I'm also planning to...

How do people test themselves after they've finished a topic or module? I just finished 'Production of Materials' and want to look for tests to test myself on the whole module to solidify my knowledge. I've tried looking for topic tests and even looked at the Bored of Studies Resources page but...
