Re: Lab 8 Execution

Does anyone know how to get deltav and deltag?
Thanks

Re: Lab 8 Execution

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

QUESTION 2

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

Re: Lab 8 Execution

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

question 10

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

Re: Lab 8 Execution

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

Re: Lab 8 Execution

#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?

Regarding Detal K for Question #13

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?

question9

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

Question 5

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?

need hel

question 14

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

Question 14

The solution posted already for question 14 IS correct, however they just forgot a parentheses at the end

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

at least that is what worked for me

Question 7

How do you get the error in k?

dont kno
Guest

question 7

for the error of k, I found K, max slope, and the min slope then averaged the 3 numbers to find k average.
then used [sqrt((k-k_average)^2+(max-k_average)^2+(min-k_average)^2)]/(n*(n-1) for n(n-1) was 3(2)=6
this is what I used I'm not sure if its right but maybe it helps

Re: Lab 8 Execution

Don't you need an error in frequency for DeltaK for 7? There is no table for that value however...so what do we use to find the max and min slope?

Question 10

Do they mean Vpart1-Vpart2/(deltaVpart1-deltaVpart2)

number 10

did ne1 figure out number 10.. im really having a hard time figuring it out. i have subtracted velocitys from both parts by the error of both part but its not working.. what am i doing wrong

help me

Q13

the units for #13 is Hz^2/kg if u guys need it
