As Physics Unit3 Discussion

not as far as i noe
maybe its some other practical and besides there are many different ways of showing standing waves.

No, it is a standing wave one, I think, I'll find it in my notes, give me a bit

 

[¦HaLo¦]

ahahah ya man sure plus the way ma paper would look !! he soo would lol =p

haha ya i do hope so =p !
good luck to u !

it depends on how much money u give em

 

[xIshtar]

Basically, it's exactly the same, except the masses add the tension, by the cord being stretched over a pulley, rather than clamping ^^
Don't worry

oh yes there is one in the book abt weights, it says we add weights to provide tension in the cord and for nothing else

ya think so =p !
oh hey n when they ask you to compare the frequency with the length ? how would the graph look like

haha man shit am screwed =p !

Think of the equation v=frequency * wavelength

frequency against 1/wavelength gives straight line through orgin, with gradient speed

thnxx to all ! =p

haha lolol am ready to give them all ma money ! but then again am broke =p so ya =p

this has all the experiments i guess =p !

 

[adhammoshasha]

My exam starts in 2 hours. good luck to you all !!

And to you. Mine starts in just over 1 hour

 

[DANGERBP]

best of luck ! =p

 

[maths maldives]

can we start the discussion now?

 

[shoaeb]

How was the paper?

 

[sarahh maria]

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

 

[shoaeb]

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

i messed up these questions lol
i got my mean as 275..i guess its wrong..dont know about the uncertainity

 

[CellarCY]

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
