HI FREINDS HOW WAS THE PHYSICS ATP GCSE O LAVEL?

[Dark Destination]

Different rubbers = Different thickness possible. Different Mass/Weight possible. Their readings are different. Experiment is void.

(I didn't write like this, but this was my general idea.)

I wrote a big answer, exceedings the lines. Do they cut mark for long answers?

I explained the purpose of the experiment, then i remember mentioning that different rubbers have different effects on the value of L, and then i mention that equal masses, sizes, weights are needed. I wrote this jumbled answer. Will i get the mark?

 

[Dark Destination]

Same.


I wrote that ammeter have their own resistances. The wire has resistance. And there was some component in b/w. All their had their resistances which reduced current.

They asked why the readings of Ammeter were different, they are supposed to be same.
That's due to internal resistance differences in AMMETERS.

For the experiment I wrote that one student holds the ruler in place wwhile the other takes the reading. Is this correct? For the rubber bands part I got 11. For the seperate anmeter readings part I wrote that after the resistor the resistance increases hence affecting the anmeter readings. For the refractive index I wrote 1.6. For rubber bands i wrote that if identical rubber bands are not used then the readings would be inaccurate.

For the first i wrote that the measuring instrument might dip in water or strike with edges and for (b) i wrote that measure the l using a string and then measure the length of string

Ammeter readings one is wrong.

And experiment is correct. :/

What? How can we use a string? How will you attach the string to the rod? It will just move ahead

Rubber band one was 11 and i wrote that indentical bands have equals masses so exert equal weight.

Not attach it. Just hold it.

 

[Dark Destination]

Not attach it. Just hold it.

But doesn't the rod keep moving due to water?

The answer to first part, what most people wrote, was that the rod is not stationary, and the rule can't be aligned correctly with the rod to measure it.

 

[Dark Destination]

Not attach it. Just hold it.

How can one know if their answer is right in this experiment? Literally, everyone has a different way of answering this question.

We had to mention equal masses? Why? :/
They said why should identical rubbers be used..

Hm dont know than :/ Guess i messed that up.
God bless our souls ,Eaxminers.

And that was the reason. Different band would have different weights. Thus the experiment would not be fair anymore.

 

[Laibaaa]

I wrote ammeter has zero error. correct?

''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.

Is this correct? Does it score 2 marks? .-.

I wrote a whole paragraph there, but if it has the words ''equal weight'' will i get the mark? I was explaining the purpose of the experiment, and that to get accurate answer their should be identical rubbers, as only then he can find out the correct effect of rubbers on the length L. And then i mentioned equal weights, masses and sizes are needed to reach the correct conclusion. Took like 5 lines.

Uh idk. Doesnt seem correct tbh. I think the good answers were one with the markers.

pray the examiner perceives you.
my teacher told me that sometimes the examiner wont give you the marks even when you're correct because they feel you're confused and writing nonsense.

Damn it But why? What's wrong with it?

 

[Dark Destination]

Maybe. I think its right.
