Physics: Post your doubts here!

[hancy pandey]

Nah, unfortunately, we couldn't see materials for phy... I only saw for bio (34) but it's going to be typical i guess....just go through the marking scheme of the years which has a circuit and pendulum questions and ur good to go

plz mention Q number

 

[nelson kokah]

no

I got this from an unauthentic source but this meets the criteria about what our teacher told us.....even tho i think this paper might be fake but it's a good example of what's coming tomorrow for sure!

not possible to have 2 graphs

What's there for bio 34 ?

No you are not bursting the bubble you are actually relaxing me because when ever the paper is leaked the replacement is a way more difficult one.

That is bloody true mate

A ways guys good luck have fun out there and be blessed

 

[hancy pandey]

I hope all your studying will pay off.
Just keep calm and give it your best shot.

I am not going to wish you good luck. Awesome students like you never need luck to be by their sides – they create their own destiny. Go for it.......

Hello i just have question about physics (9702) practical papers in general when its about calculating k constant values where they usually tell you to calculate two of it with the values you measured, lets say before that i was told to measure oscillations and i was told to calculate the period but i forgot to divide it by the number of oscillations i counted and i moved on with period of 20-30 seconds and i needed to use that to calculate my value of k with the equation given by the question, would mine be wrong if i used the wrong period that i have or would it be okay cause ive seen mark schemes where they only said "correct calculation of k"

Oh shit i did this too i just realized i think it would be ecf?

Oh man hahaha lets pray that they are nice enough to give us the mark cause f not thatll only be a low A for me

What was the question like in P33? What was asked???

Theyre pretty basic very similar to 9702_w17_qp_35

GUYS i messes up. I did my entire 10 mark table in question 1 with pencil. But i got all the values, trends and significant figures correct. But will they still deduct all marks, or like 1 or 2? Im so gone. My other papers have to be perfect. I sat for P33.

ur exam officer can take a picture of the table and send it with your exam....but dont worry they're arent that extremely strict about pencil answers. (i usually solve my maths exam in pencil and my final answer in pen lol)

lol i drew my table with a pencil too last year
its totally okay to do it with a pencil
i hope u used a dark one tho

And i udid my x axis in my graph with x10^-3 but i didnt do that when i calculated my gradient so like there goes my gradient mark and my y intercept :/

What was the absolute uncertainty in the protractor?

 

[A*****]

It's totally ok to do graphs and tables, etc. with pencil bqz our practical papers are not scanned...they are sent directly

 

[angryrider_56]

Btw guys....what were ur answers for gradient and Y-intercept? (i got gradient as 0.7 while my classmates got it as 0.5 and I got my Y-intercept to be 0.06 by using the formula and not the graph, hopefully, that's fine). And for your K question...i got 7.8% meaning they are related, right? and for improvement, one of my points were "2 values of K aren't enough to make a valid conclusion " and improvement was " take more than 2 values and plot a graph". Are my answers fine?

 

[angryrider_56]

What was the absolute uncertainty in the protractor?

the question asked about percentage uncertainty not absolute...my answer was exactly 5%. BTW guys is it fine if i have spelling mistakes in my errors and improvements?

I got 7.14
