    Physics: Post your doubts here!

    That's true. The question had both capacitors and resistors in the circuit, which kind of threw me off. Even so with enough thinking I could've came up with the correct answer and correct thinking. Although it's not necessary that everyone will find it hard, I suspect the majority will as I had...

    Physics: Post your doubts here!

    I skipped the question immediately after getting stuck for one minute, finished the paper and agonized over that one question for 20 minutes XD turns out I had the right answer but I changed it at the very last second (although my reasoning wasn't correct anyways haha). Anyhow my physics teacher...

    Physics: Post your doubts here!

    If I remember correctly 4 is also somewhat of an awkward succession, so I would only go with 1,2,5 or 10 mostly. Did my physics paper 4, screwed up a 4 mark question ._. the rest was alright, but that was kind of depressing getting stuck in the middle of the paper

    It's already amazing that you predicted one of the questions right... I have never predicted what questions will be in the exams before I went in. Gotta be confident in them all haha.

    Sorry, wasn't paying attention to the thread. Don't worry, mate I'm sure you'll do alright :) btw what is your desired grade overall for physics?

    Physics: Post your doubts here!

    Graphs huh... I'm not exactly sure in paper 3s, but in paper 5s they normally have an exemplar they place over to see if it lines up. In the case of paper 3s it might be the same, so I would expect a few marks to be taken there as well. But that would be something like 1 or 2 marks only I...

    As long as it's all sorted out, that's pretty good to hear :)

    Physics: Post your doubts here!

    Well, you're welcome :) However it's still not 100 percent that you will get 30+ as there might be some oversight you made that you didn't realise. Also, those 8 marks at the end of each of those paper... they're the hardest imo last year. You think you did alright in those?

    Physics: Post your doubts here!

    No, I don't think the examiners would be so harsh as to subtracting all 20 marks in the section, however I don't think you will only lose 2-3 marks either. Sometimes the marking schemes doesn't state what range of values you should get for the answer in one particular question, but sometimes...

    Say that one arrow is equal to 1F (arbitrary value). A gives no resultant torque, but a resultant force of 1F upwards. B gives both a resultant torque and a resultant force of 1F upwards. C gives no resultant torque or force. D gives zero resultant force but a resultant torque. If you extend the...

    Chemistry: Post your doubts here!

    In this question test 1 is for the basic identification of whether the substance is an amide or amine. Since M does not react with the acid, this means that the substance must contain an amide group (it is neutral). Since the only other group we know containing nitrogen is amine, and it would...

    Physics: Post your doubts here!

    I am fairly certain that the easiest way of calculating this is to find out how many moles of helium gas are in the cylinder and each balloon, then finding how many balloons can be filled. You should use the equation PV=nRT to do this. Use the equation to find out the number of moles of helium...

    This is the physics thread, not the chemistry thread. Go ask there, not here.

    The 2 stars have the same centripetal force as the gravitational force provides the centripetal force. This means the gravitational force acting on each object has the same magnitude, using the equation GMm/r^2.
