HOW WAS PHY P33?????

[tricky]

same here mine diff was around 10%.

 

[intel1993]

any other problem guys...for discussion..??

 

[hahahaha]

still everyone has found out different gradients some r sayin 0.043 some r 0.3 which is correct

 

[ajmaeen]

relationship true......... got 9% diff

 

[tricky]

wat was UNCERTANITY IN Q2.mine was 0.3%...

 

[tricky]

i thnk 0.3 to 0.4 was correct....

 

[intel1993]

r u talking abt tyme.....tricky......
if u r then ur ans is wong...
uncertanity was
0.1/time taken * 100....

whcih came out be 5 .6 something....................this was also confirmed by many others......so any doubt..??

 

[ajmaeen]

we had to divide human reaction time by our reading........... and it cud be frm ( 0.1 to 0.3) ......... i used .2 and got abt 10%

 

[sse2010]

uncertainy wud be 0.1-0.01...it dependz wich stopwatch r u using..if digital then 0.01 n if analogue then 0.1...so no need to worry!!

 

[intel1993]

exactly ajmaeen...... i use 0.1 as humar reaction error..
but i dont think so ke 0.3 can also be used....its only valid till 0.2

 

[ajmaeen]

ok......... i used 0.2

 

[tricky]

mine was digital so uncertainity was 0.3%

 

[intel1993]

hey tricky i still have a doubt on ur satement ...my teacher always said to take it 0.1 in every case ... i never heard abt 0.01....
may be ...

 

[sse2010]

btw i took 0.1..so %age wud be = 0.1/time x100

 

[ajmaeen]

my teacher told me the same thing........ use 0.1 or 0.2 in Q2 always....... whenever related to time .........

 

[intel1993]

ya exactly...... u got it rite.....

 

[tricky]

but our teacher told us to have 0.01/reading when using A DIGITAL STOPWATCH....

 

[tricky]

0.01/time *100

 

[ajmaeen]

well maybe............khair 1 mark tha.......

 

[tricky]

kabe kabe 1 mark b A laee jata hain soo every mark is important....
