Alevels PHYSICS PRACTICAL 34 Prediction.

[DeadbeatCIE]

We were given a weird type of protactor and we have to measure angle, I looked it closely and realised that it can record upto 0.5 degree

I wrote upto 0.5 degree, for eg
25.5 degree
What did you guys wrote ?

Same case here too i dont think we will lose marks though in fact percentage uncertainty reduces

What did you guys wrote ?

should be written to nearest 2*0.025=0.5

 

[Xaverian]

DUDE I WROTE PARALLAX ERROR AS AN LIMITATION TO MEASURE THE EXACT VALUE OF x.
AND I ALSO HAVE TERMED WIND SHIELD.
THEY AREN"T CORRECT NA ?

should be written to nearest 2*0.025=0.5

So did I wrote right angles, I mean did I quote right with respect to decimal places

 

[Xaverian]

Same

Others got like 0.024 and I got 23.8~24

I GOT -0.0180

Yes,You did .... if a smaller and common protractor had been used.the error would be 1 degrees.....

Exactly !

I did the oscillations mistake too but CIE will give marks for method since they cannot just cut the answers where we took the value of T in further questions. If the question is of 2 marks we might get 1 mark for doing half the step correct.

I donot know, but all i know that the 2 marks are divided, one for showing repeated evidence and the other for value of T

what desnsity did u guys get for water?

 

[AmbitiousPonie]

what desnsity did u guys get for water?

0.7 ish, what did you get?

 

[husnain99]

Density of water , I had o.8 something ..

 

[Shimmery woods]

0.7 ish, what did you get?

0.42

 

[Shimmery woods]

0.7 ish, what did you get?

I think i messed up the second question

 

[DeadbeatCIE]

what desnsity did u guys get for water?

0.667

Did no one write
Limitation:difficulty in measuring distance between bottom of tube and bottom of container due to refraction
Improvement: Use a coloured liquid to make it more visible
