Physics Feb 2016 paper

[FranticAmaze]

but since a load of smart Indians are taking the paper, I feel it may be higher Like last year March series IGCSE thresholds were at least 10-15 marks greater than other years' average though the paper was similar in difficulty level

How much is everyone expecting? I'm definitely getting 85+ I think but after that mark who knows

85+ in p4?? im expecting 70+
they cant increase 10-15 marks n all though -_- unfair

yeah I messed up badly in a few things but they add up to about 10 marks... the change in flux linkage question which was for 5, the LSB question, the last part of ultrasound and one point in the photoelectric current question. So accounting for silly mistakes or so I doubt I'll lose more than 15

I know I shouldn't be overconfident but this is my retake and it was much better than first attempt so I'm really ecstatic

A bunch of average Indians are taking it too. I doubt it will go beyond 61.
Who told you that? It's not true. I compared the thresholds, it was similar to the previous years' thresholds. You can check it as well.

Best case, 80+. I'm likely to get 60-62 at best. 55 minimum.

Lol good news

How was physics paper 52??

 

[DarkEclipse]

How was physics paper 52??

It was alright. Easier than some of the previous years.

 

[FranticAmaze]

easy but i messed up a little in the 2nd qs

 

[dwishasj]

I think I subtracted the values in the heat loss question. The paper was last week. I don't remember 90% of it

it wasn't last week... it was yesterday!

How was everyone's chemistry p4? What were your answers for the question about V and W, the elements in the adjacent groups that form acidic gases with O2 and ions VOm^- and WOn^2-?

It was good
I got N and S for that question

 

[escpsts]

I got the same thank god!! I was worried mine might be wrong as everyone else who gave took the exam at my school had other answers...

So from what I recall the questions were:

- Buckminster fullerene
- Transition metals
isomers of a complex, Kstab
- Electrochemistry
feasibility of reaction
- Nitrogen & Sulfur
- Entropy/Enthalpy/Gibbs free energy
- Reaction kinetics
CH3CHO and OH-
- Polymerisation

what else?

Easy, but I made a few stupid mistakes (like buckminsterfullerene's hybridization and one of the Electrochemistry subquestions).

I wrote the hybridisation wrong too. What else was in that question do you remember?
Which subquestion in electrochem?

 

[DarkEclipse]

Which subquestion in electrochem?

Something about excess chlorine and phenol?
The hydrogen peroxide one.

Hybridisation of what ?

if anyone remembers any question the pm me please?

Hey so those who gave the feb 2016 9701 physics paper
how was it?
Also do you remember the questions that came up and their sub-parts?
I know there were 13 questions
So i remember these:

1. Gravitational - moon orbits
- state newton's law of gravitation
- prove v = root*GM/r
- ratio Va/Vb
- ratio Ta/Tb
- time period

2. Ideal gases
- define internal energy
- why potential energy of ideal gas is zero
- find the number of molecules
- show how we get 3/2 kT

3. Specific heat capacity – heater
- define specific heat capacity
- why 2 readings are taken
- calculate value of specific heat capacity
- calculate resistance of heater

4. Magnetic and electric fields
- find direction of electric field for the proton
- q/m ratio
- find mass in u
- number of protons and neutrons

5. Oscillation
- find amplitude and time period from graph
- calculate k.e.

6. Magnetic fields
- change in flux linkage till 3cm
- speed of coil
- coil and flux linkage and emf graph

7. Capacitance
- define capacitance
- prove 1/c = 1/c1 + 1/c2 + 1/c3
- calculate total capacitance
- charge on capacitor
- pd across capacitor
- switch is changed so calculate pd

8. Op-amps
- complete diagram
- calculate resistance of second drawn resistor
- advantage of gain in negative feedback
- diagram of Vout

9. Photoelectric effect
- define photoelectric effect
- effect of decreasing wavelength with same intensity on photoelectric current
- E and 1/lamda graph

10. Communication
- define digital signal
- 1100 in digital form when LSB is 2.5mV
- how to improve regenerated signal

11. Ultrasound
- ratio of I1/I2
- ratio of I3/I2
- what happens to I3/I2 ratio if the difference in acoustic impedance is increased

12. X-rays
- what is hardness
- how to reduce hardness
- advantage and disadvantage of CT scan over X-rays

13. Nuclear - radioactivity
- show that decay constantly is equal to somthing
- calculate mass of radioactive isotope
- time for activity to reach the value


So if you could please help me fill up the questions that came up I just like to try and predict what I had solved etc... so yeah
Also if I have missed out any sub-parts in the question then lemme know as well

May I ask what came out for Chem/Bio/Physics Paper 3 in Feb/March series?

 

[Crowned Hopeless]

You kind soul. Didn't you do Maths, Biology or Chemistry? and if you could enlighten us on that please
