ques 2 eq. 9: does anyone understand it?

I have abs(.5)* (constant*Deltamu/Deltamu)*v

Does anyone know how to get deltav and deltag?
Thanks

Can someone help me with deltamu and deltav on page one? Either I'm plugging it wrong or I"m getting it wrong :/

delta mu= mu*sqrt((Deltam/m)^2+(DeltaLprime/Lprime)^2)
delta v= v*1/2*(Deltamu/mu)

does anyone know how to get delta k for q13? also, the slope I got for the first graph is linear, so how do I get the error for that also? thanks

do you divide by the difference (error Part I - error Part II) ?

nevermind i got it! =)

Any body have any hints for #8,9,and 14?>

#8 v*sqrt((DeltaL/L)^2+(Deltak/k)^2)

#9 (velocity from #4 - velocity from #9) / delta v from # 9

#14 g*sqrt((Deltamu/mu)^2+(Deltak/k)^2

Does anyone know the units to #15?

Hi,
Isn't Delta K supposed to be (Slope Max-Slope Min)/2 ?
I got like 10000 (which may sound too big) that doesn't seem to work for the answer (gotta be less than 10% of K, I guess)

can someone tell me if my experiment had problem or is there other way to calculate Delta K?

Never mind i got it. I was thinking too hard.

I am having a problem with quesiton number 9, and I don't think that the post that give the answer is for the right question...

How do you figure out delta v for question number 9. I tried using the previous eqn (# and it keeps marking it incorrect. Any help

do we actually have to type or draw something in for this question on maple ta? because it says it is worth 1 point.

what is delta L?

the answer for question 14 posted isn't correct I keep getting it wrong =/
