for the second last question? i got it as 230±8mm

 

[U stalking ME]

what did you do for question 6, and what were the units of viscosity

viscosity was Nm-2 s
not sure abt Q6 answer i got 328 ms-1, i dont remember the mean value

 

[sarahh maria]

no its N m-2 s not s-1 cause velocity is m/s so the second goes up

 

[U stalking ME]

Mean was 320 +-8 , well that's what i got. The viscosity unit was N m-2 s-1. This is beacause viscosity is F/vr, which is n/m*ms

speed is ms-1 , its n/m*ms-1 not n/m*ms

yeah one of my friend got 275..and the other got 320..but i guess its 320..cuz then the speed of sound gets closer to 330..well lol

LULZ! PEANUT BUTTER JELLY TIME

 

[sarahh maria]

i got the speed of sound to be 327.67

 

[shoaeb]

i got 281

 

[sarahh maria]

and for †he experiment its self number 6 please someone write the correct way to do it

 

[shoaeb]

if i knew the correct way to do it..i wouldve writen it a long time ago.

What you guys get for the first question btw?

 

[sarahh maria]

which one?

 

[CellarCY]

where it gives you 0.26 0.27 0.29 0.42 0.26 to calculate suitable average and uncertainty

 

[shoaeb]

the anser was the one with the uncertainity of 0.02..u had to take the mean..remove .42 outa it..cuz its an anomaly..or w.e..i got this one wrong too..lol over confidence..marked the one with 0.015..but then it rounded up to 0.02

 

[shoaeb]

guess what
my uncertainity was 240 xD

 

[CellarCY]

oh **** you can round it up??xD i thought you should leave it the way it is damn it else i would have gotten that one right oh well only 1 mark i got other 4 right though xD

 

[shoaeb]

LULZ..i made the same mistake man.
