as far as ur talking about the winding thing.........the measuring tape is perfectly okay......check the june 2010 paper 4 (5054/41), measuring tape can be used......the foot method is inaccurate..bcoz it dosent apply the main physics measurement techniques.....yes you are right, about using 8 tapes....but it is the only measuring that is suitable after the trundle wheel.

MashaAllah, I wrote long measuring tape, calibrated in metres, markings made at intervals if tape finishes, and measurements continued.

and what did u wrote in the last part of the last question

They asked why the value on the Voltmeter was decreasing when person moves infront of the solar pannel so i wrote " Less electricity is made so less emf is induce in the circuit so Voltmeter value decreases and the prevention was to place the Panel infront of the light while Placing the meter somewhere else toward the person..

To prevent it i wrote that use a digital voltmeter and conect it to the computer

what about the procedure to find out the volume of glass stopper...should it be done with the beaker or measuring cylinder...i wrote beaker. is it wrong?

Cylinder is more accurate, but beaker would also be correct InshaAllah.

10.0cm

You are right that it should be 10.0 but in mark scheme 10 is also written and is correct 10.0 is just better

Cylinder is more accurate, but beaker would also be correct InshaAllah.

But doesnt Measuring Cylinder have a small Mouth so the Glass stopper could be Stucked

btw what was appratus A ?

Which apparatus a

 

[Sparky123]

They didnt state any diameter so???
InshaAllah, the ms would be lenient and bothwould be correct

 

[robinhoodmustafa]

Which apparatus a

I meant what the other quantity they ask fr density. i wrote Mass and electronic Balance be use to measure it

 

[Nouman1997]

I meant what the other quantity they ask fr density. i wrote Mass and electronic Balance be use to measure it

Yup i wrote mass and beam balance i think both are correct

Do you have Bio and Add Math

 

[Bilal Khan]

Hey , is 10.5 cm right answer of the focal length ??
bcoz from my graph i was getting this value..

 

[robinhoodmustafa]

Do you have Bio and Add Math

yes

 

[Nouman1997]

yes

How are you preparing for bio

 

[Nouman1997]

Dont know but it might be right as the mark scheme allows leniency up to half small square of graph

oh,right then..
hey , what did u write in what improvement can be made to measure volume accurately ??

 

[Nouman1997]

Repeat and average

i wrote avoid parallax error while reading value from measuring cylinder..

 

[Nouman1997]

i wrote avoid parallax error while reading value from measuring cylinder..

k ididnt wriTE IT CAUSE IF I WROTE IT I WOULD have to write its whole definition

 

[robinhoodmustafa]

How are you preparing for bio

Good. I will revise chaps again
U?
