shud it b within da limit of accuracy or beyond da limit of accuracy

the question about the mass of the metal 50cm ruler? i wrote her results are within the limits of experimental accuracy. u?

but the diff.>1 gram right?-

 

[JimmyCarter]

but the diff.>1 gram right?-

the difference was so little tho so thats why i said its within the experimental accuracy, i dunno

the good news is as long as u justify the statement you'll get full marks
source: 2 Marking schemes

I wrote 3d.p the logic behind it was that it's an experiment so the results should be exact or closest to exact...But I guess ones again my6 brain messed the thing :/

3 d.p or 3 s.f ??

 

[areebaization]

3 d.p or 3 s.f ??

I wrote in 3d.p wbu?

 

[Abby ay]

exactly...it doesnt matter at all.....& after 24 hr i will forget da ppr even..

Haha true

 

[Abby ay]

I wrote in 3d.p wbu?

i wrote 3 s.f
1.50

 

[shalala]

I got 1.55 as the gradiant and 1.6 as the resistance. 1.6 b/c the voltage was in 2 decimal places!

 

[bluefa1con]

answer was 1.5 ohm since most of the values given in the table were in 2 sig figures
and if u take individual resistance of each values some are less than 1.5 but all of them rounds to 1.5

 

[Osmix1995]

yeah they gradient was 1.51 i wrote it in 3 s.f

and the gradient 1.5 ohm

 

[Osmix1995]

but the diff.>1 gram right?-

yes the difference was more than 0.1 ,,,, it was 0.125 if i remember correct

so i wrote it was not within the limits of experimental accuracy

 

[white rose]

hey guys, wht did u rite abt mass of metr rule?

 

[white rose]

i rote it as 40g

 

[*MK*skydiver :D]

i rote it as 40g

i wrote 100 grams ......??

 

[white rose]

i wrote 100 grams ......??

i think 100g is correct...40g is too less

 

[shalala]

Wasn't it the mass Of the load? :/
And whta did you write for the last answer? And the 1st question 2nd part about how to find the centre of mass?

i wrote 100 grams ......??

i think 100g is correct...40g is too less

 

[white rose]

Wasn't it the mass Of the load? :/
And whta did you write for the last answer? And the 1st question 2nd part about how to find the centre of mass?

no, it ws mass of da metre rule....for centre of mass, keep da centre of mass on 90cm of da ruler

dude srsly no calculation was to be done? I got 213.smth after calculation :/

 

[natsume hyuga]

what abt the problem or difficulty you may come across that may be source source of error?
