Here you go!
it took me some time to print it and then solve and then again transfer them to pc through my mobile so srry for the late reply

Thanks a tonne.

What's the difference between moments and momentum?
And when to use momentum, I know when to use moments
I also am confused because I thought they were the same but turns out each one have different equation.

I'm not sure if momentum is in igcse syllabus but it is the product of velocity and mass...
It helps in calculations involving collisions.
Moment = product of magnitude of force and the perpendicular distance from the pivot.
Momentum = product of velocity and mass of an object (at a particular time)

Anyone who wrote Physics Variant 1 ?(31 and 11)
I think that it was kinda average....................

hi, out of extreme anxiety i checked other people's past year results of past year igcse's on the internet. i noticed that any grade below 90 only received an A????? and when i checked the threshold, the minimum mark to receive an A* was so much lower (only 78 for some subjects)? how come? this is making me so stressed out hahah if somebody knows why its like this please tell me i am seriously stressed out of my mind
thankyou

Variant 1 yeah

For variant 1
did you guys add the pressures or subtract?
Also, in multiple choice did the weight of both magnets increase, decrease or what?
In multiple choice, was the answer for equilibrium the block with 2N and 2N or 4N and 4N

Subtract
Decrease (Not sure)
There was no 4N? Went for 2N

Yes, even I subtracted
The weights even I am not sure, I did one decrease and one increase
I went for 2 N...................

 

[Iris Dylan Lane]

Increase, why?

i subtracted
on magnets i was not sure
went 4 2N

Which subjects ? Cause the march session dint have all subjects

 

[XxChampXx]

Which subjects ? Cause the march session dint have all subjects

I have english literature paper 2 and additional mathematics left

 

[Abdurrahmanmuhammed]

Both these subjects weren't there in the math session
