HI FREINDS HOW WAS THE PHYSICS ATP GCSE O LAVEL?

[Dark Destination]

It said ' Ratio ___________________'
I double checked.
And we had to write the RATIO correct to sig fig which was 36:23.

No, they said that the REFRACTIVE INDEX can be calculated with the RATIO GIVEN.
We had to input the measurements and get the value for refractive index.

Refractive index is not a RATIO, it's a value.

funky brat We had to write ratio? What are they talking about? :/

 

[Ram97]

in q.3 last part did we had to make line by estimation or by an angle

 

[Abdul Hanan]

i am sure it said
ratio______________.
so i wrote 36:23

 

[funky brat]

No that's the same thing. No difference in ratio and index.

 

[Ram97]

No that's the same thing. No difference in ratio and index.

I went with a different method for Rod.

Take a marker - Mark out where the water level ends.

Take out the rod, measure the rest of the length.

My R index was 1.60 and volume was 2.0 cm3

What about question 1? Did you read the entire thread?

 

[Fate0]

Definitely very easy.
Losing 1/2 marks maybe but still happy.

 

[DaniyalK]

You don't write refractive index as X:Z... Furthermore, in the past papers, whenever it says "to appropriate number of significant figures", the answer is always a decimal number.

Nabeel, we got the Physics Master.

it did not ask for refractive index it said "ratio____________________

Where are you losing marks?

And check the first two pages, i tagged you. :/

Lol, yeah.

Um one on significant figure one, last part. Wrote 1.85
And one on maybe the why the reading of ammeters were different.

 

[Hasibul]

Because water keeps moving, and rod keeps moving too, that is why it is difficult to align the rule with the rod.
Right or not?

What did you write in same identical rubbers reason?

i wrote the same thing bro..hope its correct

 

[Hasibul]

11

i also wrote it

Silly mistakes.

I wrote ammeters have different resistances. Is that right?

 

[Fate0]

Yup that's correct.

 

[Dark Destination]

Yup that's correct.

But question 2,3,4 were easy. Question 1 was the real deal. :3

What were your answers to the first two parts? And to that identical rubbers one?

Question 1 part b. How to measure Length L correctly.

I said immerse the rule into the water as zero mark co-incides with the water level.
And then align it vertically with rod, and use set-square to find the answer. I also drew all this apparatus on the figure.

EVERYONE HAS A DIFFERENT WAY.

Someone is using a cobalt chloride paper.
Someone is pulling out the rod, and marking the water prints.
Someone is marking the beaker.
Someone is inserting the rule on the side.

Is my answer right?
