AS Physics P1 MCQs Preparation Thread.
Q.34. I think for this question you will have to use R=V/I. I will straight away eliminate D because at D, current is constant while V is increasing so R will increase the most at D. (*Note: You can only use R=V/I when there is a straight line(Ohm's law)) For the rest I think you will need to... -
Nice to meet you too~~ Hopefully we can become friends and discuss subjects together.

AS Physics P1 MCQs Preparation Thread.
ummmm... regarding the question 33, I think we shared a different opinion. (a)Will be wrong because the speed of the charged particle not only depends on the e.m.f of the power supply but also the potential difference across the wire as well. (b) Wrong because the speed of the charged... -

hmmm.. It's a chemistry discussion right? But I am now looking at your physics past paper post. Hahahah It's okay. I will try my best to help out anyway:) Q.11. Principle of linear momentum stated that the momentum before collision must be equal to the momentum after collision providing no... -

Q.30 Is about how we can observe interference pattern. According to my understanding, we can only see interference clearly on the screen which in this case is line XY. We cannot see any interference along line RS. Imagine using a monochromatic light(Laser), you can only observe the interference... -

Chemistry and Physics AS paper 12 MCQS
You will need to look at the voltage output. At first the voltage is 5v and after it passes through R1 the voltage output dropped from 5v to 3v and this means that 2v voltage is used in the R1 resistor and this is why the voltage of R1 is 2v. Same goes for R2, after passing through R2, Voltage... -

Q Q.35 R1 requires 2v, R2 requires 1v and R3 requires 2v and in series the current should be the same at all point. Since R1 and R3 have the same potential difference, I would say that Resistance of R1 = Resistance of R3 based on the formula R=V/I where V is the same and I is constant. so my... -

For Q.40, We will have to look at the hydrolysis of esters using base(NaOH). Try to separate or split the esters into Sodium salt(Not C.A because we are using NaOH) and also alcohol. (1) is actually the alcohol product produced by base hydrolysis of ester. (2) is the sodium salt produced by base... -
Chemistry and Physics AS paper 12 MCQS
Very sure of it. Because no hydrogen is bonded to the C=O carbon and we have 4 C=O bonds when we break all the double bond and since it's a strong oxidation reaction, one of them should include a C.A group. So overall we have 1 C.A group and 3 Ketones group and C.A will not react with 2,4 DNPH... -

Q.28 First thing that you have to do is to break every double bond into their respective compounds because here involved the use of hot and concentrated potassium permanganate(ALL THE DOUBLE BONDS IN THE COMPOUND MUST BREAK). Once you break the double bonds in the compounds, you will get 3...
