    Hard/challenging paper 3 chemistry.

    I'd like to know if there are any papers you find hard or challenging, so I can do them myself for practice. Also post the difficult question's number. Thanks ;)

    Chemistry Doubts: IGCSE Paper 3

    For this you cannot just draw brackets and n, you need to show at least 3 continuous bonds, as stated again and again in the ms.

    how to draw this circuit question? 2005 oct/nov physics p6?

    An ammeter, the same as shown in circuit (ii), 2 resistors, with the box symbol, CB and BA in series with the voltmeter in parallel across them both and another resistor CD in parallel to these two resistors.

    Physics, Chemistry and Biology: Post your doubts here!

    I did that same question and I don't seem to understand why 5 sig. figures is inaccurate, I thought more sig. figures, i.e. 5.4123212, is more accurate than less, i.e. 5.4.

    Biology Paper 32 2012 Discussion. 24 hours have passed.

    Answer for the first question was microvilli. I was wondering about the question about the monkey thing, what adaptations might it have for living in the dark. I wrote "It may have a strong sense of hearing and smell to be able to detect prey which it cannot see, and to detect predators as well.

    Not all of them, it only had the ones for electricity.

    Physics doubt

    Current is inversely proportional to resistance ( I think ). So double the resistance gives u half the current, so you must find the value for X which gives a current of 1A, so when it's doubled, it gives a current of 0.5A. So you need to apply a proportion to find that out. Someone correct me...

    physics paper 6 ?

    Do you print your past papers, if so make sure you set the printing size to "Actual Size" and measure from the arrow tip.

    Physics, Chemistry and Biology: Post your doubts here!

    There are questions that keeps coming every paper which I can't seem to get right in Physics Paper 6. 1. What are the common causes for error in an experiment ? 2. How to improve reliability ? 3. Variables that should be kept constant when repeating an experiment. Anyone care to lend a hand ?
