Physics p22

phase difference was askd
ie 360 and 180

Re: Physics p22

I think it was phase difference

 

[Mobeen]

it was phase diff .. and i wrote pi and 0 .. i messed up the last part of that question too

 

[Octahedral]

Btw how can everyone say that gt will be low?How can we be sure?The paper was rather strange I don't even know if half the stuff I did was right.But that is no guarantee that gt will be low though i hope it is so posting.php?mode=reply&f=26&t=8216#

0 is not possible becoz is it frist maxima q, was asked abt second

i suck at waves !

guy's the acceleration question... did anyone use mg - F= ma ?????
because the formula gave the frictional force, not the resultant

because the formula gave the frictional force, not the resultant

and i think it also asked for the deceleration producued due to the frictional force .. so we would only use F=ma.

 

[akbararshad]

it dint ask d deceleration, it asked d acceleration of d raindrop so we hav to use W-f=ma

 

[Mobeen]

i think it askd for the deceleration from the "frictional force"

 

[Talha]

any1 tel dat whether we had to write acc. as -ve 4.9 or +ve 4.9... The graph was showing +ve acc. so i wrote +ve 4.9...? is it correct??

 

[intel1993]

its correct

 

[yubakkk]

i think its negative because fr. reduce velocity

 

[akbararshad]

m damn sure dat it asked fo d acceleration of d raindrop not da deceleration frm da resistive force....... nd it was positive

 

[yubakkk]

question said accleration or deacceleration?

Ok guys, please tell me if the last question had asked for "phase difference" or "path difference"
I thought I read path difference and wrote lambda and 0.5 lambda

i also read path difference....and there was nothing written abt phase difference.......bt everyone is saying it was phase difference...i dont know wats happening here....

Acceleration!

bdw wat was d answer???

i also thought it was path diff and wrote lamda .. but then i looked at it again and saw it was phase diff actually ..so changed.
