HI FREINDS HOW WAS THE PHYSICS ATP GCSE O LAVEL?

[Abdul Hanan]

Can someone answer the question about number of rubber bands needed to sink the rod?

11

What range :O I didnt have any question like that

 

[Dark Destination]

Because identical masses.

That's it?
I wrote a long story, that included the words ''Equal mass, weight, size'', ''Accuracy'', ''Purpose of experiment''..
Like i mean, i wrote a whole essay there. Do you think i will get this mark?

I am asking the range of acceptable answers for last question.

You'll get the mark.

You'll get the mark.

What about me?

WHY USE IDENTICAL RUBBERS?

I wrote its because itll be the same mass,so then its accurate and fair...i hope its correct

What is range of acceptable answers for last question i.e volume?

 

[Dark Destination]

The student was trying to investigate the effect of number of bands on the length L.
So it's logical that to have a precise conclusion about the effect of that number of bands, he should use same identical rubber bands. That's what i wrote.

But that is no answer. That is just an interpretation of the experiment.

We had to write something like ''Identical rubbers have identical masses''..

1.9-2.1 max as you had to measure from given diagram

But you said you wrote about mass?

You'll get the mark, funky brat

There was a problem with my scale. Each value 0.1 cm greater. I calculated 2.2 cm3

 

[Dark Destination]

But you said you wrote about mass?

I don't remember what i wrote :/
I started of that interpretation.
Than MAYBE said, that different sized rubbers have different weight and they produce different results of Length D.

I have idea. I hope there's some range. Mine was 1.9.
2.0 is a 2 sig. figure, this still escapes my understanding.

What? The divisions were 0.1 cm apart?

What did you write?

You'll get the marks for this part, as you calculated the entire thing.
But are there marks for writing in correct s.f if they asked for it?

What was the REFRACTIVE INDEX? 1.6 or 1.3?
