HOW WAS PHY P33?????

[Ab.R0xi0uS]

Ohk someone tell me or pm me my answer

i averaged time from stop watch (stop watch least count was 0.01)
t1 = 4.14
t2= 4.16

avg t1 + t2 /2 = 4.15s

took this value as t - time of fall

while calculating percentage uncertainty i used the absolute error as 0.02 (adding 0.01 and 0.01) - instead of 0.01 what majority did

Did i screw up ? :| should i have use 0.01 as abs. error ? but i did show the averaging of two ts ..

One more thing if your constant k is wrongly calculated
are you credited for your explanation of relation between k ?

BUT ME QUESTION !!

[ashhadazam]

NO u dint screw up I think its absolutely fine

 

[Ab.R0xi0uS]

is it so ?? thank you mr.ashhadazam

 

[ashhadazam]

lol u make me sound like a 35year old !! Ya it is fine if u shwd ur working !

well the y-intercept has to be positive i got negative our examiner tld us after the exam nd even the equation said so
i got gradien 1.1 is it right nd it has to be 0.1s for the uncertainty coz its human reactio time its given in examiner reports as well

 

[ReDdevILz]

Guyx plx confIrm? was da gradIent +ve or -vE!! thats damn too confusINg!! havent recIeved any confIrmation yet!!
and does ECF goes on In thIS practIcaL??

 

[intel1993]

gradient is positive ....confirmed abt that...........

 

[xarak]

lol...my gradient wuz compplleettlly retarted....it wuz 8.6 x 10^-16 nd y intercept wuz positive!!rest all paper wuz gewd!!nd wt were we suppose to rite for the justify the number of significant figures for k??

mine y-intercept was also positive ...... but my gradiant was even crazier 232.???

chalo koi to hai mere saath =P...i thot i wuz the only one!

 

[xarak]

yeah nd one more thing...wt were we suppose to ryte on the x and y axis..i wrote 10^2 ,10^4... 2 cms etc on x axis nd 0.01 on yaxis 4 cm...i noe im wrong..pllz confirm!=(

 

[Hanna92]

Okay so i did the variant about just a series of resistors...that was really too easy.....and then the second part was about oscillations with a short and long tube....i was also done in like an hour.......so did anyone do this one??.....my gradient was exactly 4.0.....and my y-intercept...was like 0.002.... and i did convert all my readings to ampere....anyone here to discuss???

I m sure on 1 thingthat the absolute error using a stop watch is always taken as .1 to .2 seconds since human reaction error is involved u can chek marking schemes. as for the least count it is only used in things like metre rule or measuring cylinder if any1 can have a reaction time of 0.01 seconds than he has super speed it is impossible. so the error for time is at least 0.1 and maximum 0.2 i dont think taking 0.4s is a good idea.

I did the same thing. i averaged 3 values 0.03.

 

[intel1993]

ya s same here i take theree values n take its average value...........

can u tell me on wat was ze practical physics??thx
