Physics paper 32 any1?

I'd recommend not to use the parallax error point cause some places they didn't accept it so b on the safe side
N in places of significant figures always write that we consider the least number of significant figured from the raw data

Ummm okay JazakAllah

guys read this

Good Luck all InshAllah we all will do great don't panic ,do ur best and leave the rest to Allah

Though this guy did mention this experiment abt pressure n I think it will b somewat similar cause the variants that r on the same time r usually simple.

Yeah the pressure thing ,we might need to push a liquid or smthng with a syringe.

Yea inshaAllah Allah will help us through

Can you please explain significant fig thingy .......... i didn't get it

They usually give a one or two mark qs that why u have selected these many s.f. In ur reading so my sir told me that we always consider the least number of s.f. from the raw data though their can b a range of s.f. in ur raw data. That's all I know

Btw ppl how do we reduce the heating effect of the resistor in a circuit?

use fewer wires (crocodile clip wires) for ur circuit connection

 

[S.Mashaal.N]

the easiest way to find percentage uncertainity is:
if you have 3 set of values, find the rang: highest value - the lowest value
find the mean of the 3 values.
% uncertainty= range/mean x 100%

i have doubt like when measuring by a metre ruler it measures nearest to 0.1m right? as the smallest reading that can be obtained is 0.1m right? so uncertainity would be 0.1 if only taking one reading only?
and what the difference between absoulte eror and the normal one i remember absoulte one was half the smallest reading is it correct? an we use it for what?
thanks guys

See absolute uncertainty is the range of value we are unsure about so for a ruler least count is 0.1 we Unsure that the value for eg is 23.4 so with this uncertainty it can be either 23.3 or 23.5

can u please clear the other queries i have put

did any one got bubbles for the second experiment ?? i tried like for 50 min but was not able to produce a single bubble ..

yup, I did
