to find percentage value do this 100% sure
{ [ ( largest_value - Smallest_value ) / 2 ] / [ ( average_value ) ] } x 100 = percentage uncertainty
eg we have d1 = 6.8 and d2 = 6.9
percentage uncertainty = { [ ( 6.9 - 6.8 ) / 2 ] / [ ( 6.9 + 6.8 ) / 2 ] } x 100 = 0.72 %

FOR K VALUES DO THIS
find 1 percent of bigger k value and minus that from the bigger value or add it to small value and check if they lay within 1 percent of each other

what do you mean by K VALUE? i dont understand...

Thru won't repeat an entire experiment I know...that already came in the November examlast year

 

[talal096]

Electricity is not coming i guess

 

[Fahm Deen]

Guys what do we comment for the percentage difference?

 

[MYLORD]

what do you mean by K VALUE? i dont understand...

i still didnt get it
u have to take average value or smaller or bigger value ??!!
Everyone's confusing me !!

 

[Snowysangel]

Is anyone done with it?

Me. Made a stupid mistake with the graph. And it took me 1 hr 15 mins just to take measurements because there was something wrong with my apparatus. It just won't oscillate. Then the lab attendant came and fixed mine and the rest of the student's apparatus.

Hey, in the second one, how many marks do we lose for using the diameter instead of the radius in all the calculations?

I think 1 mark or two at most. It's ECF so you don't have to worry about loosing a lot of marks.

Can u help me with this thing
I dont

How was ur paper ?

 

[Snowysangel]

Okay people no discussion or Ill report you to the xp moderator...how can u risk sacrificing your grade?

 

[10apples]

what was your range?? ok ....apology

Okay....not sure...and yours =)

instead of finding Y-Intercept....I Found X-intercept
how many marks will i loose...as in the next question we have to again write this value...?

 

[unkidd]

Guys if i used diameter instead of radius will my calculations of k be incorrect as well or will i get ecf

No....It will be around The RANGE =)

Guys, what was your diameter? And the value of m and c?
