Physics p6 last question

[Nasirkhan09]

i got 1.5 but dont worry you will get the 2 marks its an error carry forword means ur answere for the index depends on the two pervious so relax and prepare fpr tomrrows exam

haha i know it already...

 

[EpicLol]

haha, thanks alot man!
But i thinki did really good, except that question and i lost one more mark! so yeah really bummed that i couldnt get that right tho!
what are you expecting??

I did variant 1 and we did not have to find the refractive index of anything... XD

 

[Starkiller96]

In Variant 1, What did you guys write the Mass of the Metre rule?

 

[EpicLol]

It was 70, not 71. :x
And for the line of sight you just had to continue the line from 70 horizontally and label it. c:
Also, I'm pretty sure the graph was Force against distance.

it was 71 not 70....I think....which variant and which question?

 

[EpicLol]

In Variant 1, What did you guys write the Mass of the Metre rule?

What did u write?
I wrote 0.5N as 10N = 1kg and I assumed it being like 50g which is 0.5N....

 

[3amak]

i did variant 1

 

[kareem]

r u sure of ur calculation?? most of the people got around 1.4

ye there should be a range in ms

 

[Starkiller96]

i did variant 1

Hey, what Mass did you write for the metre rule?
I wrote 70grams.

 

[Maroon 5]

what about the graph ? what scale did u guys use ?

 

[JOEJOE]

v62
condition for proporional line : straight line(1) from the origin(1) right??

Condition for diff labs =
different temp cozz different climate
there might be draught coz of diff weather

Precaution in ref question
Avoid parallax or Repeats right?

Hey, what Mass did you write for the metre rule?
I wrote 70grams.[/q
i wrote 0.12kg i found this number in past papers

Condition for diff labs =
different temp cozz different climate

Precaution in ref question

For the temperature conditions i wrote: High temperature and low temperature and difference in humidity
For the precaution i wrote repeating the experiment

 

[JOEJOE]

what did u write for the proportional line conditions bro??

 

[Diablo]

what did u write for the proportional line conditions bro??

not sure of my answer but i wrote Straight line from the origin and a steep slope

 

[MTH]

how was the graph a best fit or curve most mark schemes don't mention about curve i drew best fit

I wrote curve ...

 

[$Vettel$]

nvm man theres a range for every answer

 

[ahmed99]

why is spirit level not suitable?
v62

 

[JOEJOE]

it might add force so reading changes thats what i wrote....

 

[Moi]

1) for the Refractive index, we all have different answers because each one drew a line of diffrent size (almost), so minimum differences could lead to different anwsers, marking scheme will have range !
2) Line conditions: straight and passes through origin
3)the spirit level question, i wrote it adds extra weight so the ruler may tilt
4) The reading of cylinder was 70, and each sphere is 0.53 cm^3
5) I wrote Distance against F .. correct or no?
6) i wote for the unexact result= because of different starting hot/cold water temperature and different room temp.

 

[fille spéciale]

What did you guys get for ______against_______? was it f against d or d against f ? Does it make a difference ? as it proportional ?

force against distance...
