Question7 on Maple TA
Does anyone know how to calculate Value of DeltaQ(correct) and Value of DeltaQ(neglect mass error)?

Re: Lab 10 Execution
Has anyone figured out Question 10?
Delta(W/Q) = __________________
Delta(W/Q) = sqrt((DeltaW/W)^2+(DeltaQ/Q)^2)*___
So what am I missing? Is it multiplied by something?

Re: Lab 10 Execution
For above you have to multiply your error by W/Q since they are asking for the absolute error. Your equation is right just multiply that by W/Q
aS asked for above I also need some help on finding Delta Q(correct) and Delta Q(neglecting mass)

Re: Lab 10 Execution
I tried that as well, Maple TA is marking it incorrect. At the end of my equation I add *(W/Q)

Value of DeltaQ (correct) = sqrt((Deltam/m of water)^2+(DeltadeltaT/DeltaT)^2)*Q of water
Value of DeltaQ (neglect mass error) = sqrt((DeltadeltaT/DeltaT)^2)*Q of water
Value of DeltaQ (neglect mass error) = sqrt((DeltadeltaT/DeltaT)^2)*Q of water

question 10
for question 10 i used sqrt((DeltaW/W)^2+(DeltaQ/Q)^2)*(W/Q) and it was correct

question 8
I'm stuck on the value of deltaQ(correct) and
Value of deltaQ(neglect mass error)
Value of deltaQ(neglect mass error)

units for specific heat
what are the units for specific heat?
i think its joules/ gram degrees c but im not sure how to enter it into maple ta for question 1
thanks

Re: Lab 10 Execution
I tried Question 10 again this morning and got it correct. I must have misspelled something or forgot something. Thanks!

Re: Lab 10 Execution
what are the answers for the second part of questions 7
or how do you compute them?

question Guest
Question7 second part
for the Value of deltaQ(correct) i used sqrt((Deltam/m)^2+(DeltadeltaT/deltaT)^2)*Q
for deltadeltaT i used sqrt((DeltaT_i)^2+(DeltaT_f)^2) and for delta T i used TfTi and for Q i added all the Q's
My answer is still coming up wrong. for m do i have to add all the masses together and use .2 for deltam?
What am i doing wrong?

Re: Lab 10 Execution
For Question 7 all it is asking for is the Q for each component. How do you find Q? [Hint: It's on the Preparation Lab 10 sheet. It's Question 2 and labeled as (2). It also tells you what each variable is supposed to represent].

Question 7
Yea, Q is easy, what about the bottom part of question 7, regarding Delta Q correct, and neglected Mass Delta Q. I know the equation, which i got right on the next question. What I want to know is what to use for the M, Delta M
Is Delta T= 0.5
and T= (TfTi)?
Thanks for any help
Is Delta T= 0.5
and T= (TfTi)?
Thanks for any help

Re: Lab 10 Execution
I believe DeltaT is another number you had to calculate using 0.5^{o}C. I do think that is the correct value for T. I have lab on Wednesdays so I haven't done calculations yet.
Try them in MapleTA and see if they come up correct, if it doesn't try other values in the calculations.
