ohh thanx
how about the units for k and delta k Sad

Guestttt on Thu Dec 04, 2008 1:26 pm

what are the units for fn in question 6?

D on Thu Dec 04, 2008 1:50 pm

how do we do #5 in maplteTA or we just leave it?

user 87 on Thu Dec 04, 2008 3:40 pm

In order to find g, g=4/9*mu*L^2*k
and Deltag =g*sqrt((Deltamu/mu)^2+(Deltak/k)^2)

user 87 on Thu Dec 04, 2008 3:45 pm

The units are m/s^2

The units for #7 is Hz.

DJ on Thu Dec 04, 2008 6:26 pm

It's been asked numerous times, but how do you find Delta K in questions 7 and 11?

DJ on Thu Dec 04, 2008 6:34 pm

MapleTA accepts 1 as the answer to the slope errors.

DJ on Thu Dec 04, 2008 6:42 pm

MapleTA accepts 10 as the error in question 13.

Did anyone figure out how to calculate the velocity for question 9? I've tried doing it several ways and still can't get it

Guest01 · Guest01 on Thu Dec 04, 2008 7:35 pm

Velocity for Question 9 is (2*L)*k where k is the slope from Question 7 and L is the length from Question 6.

Regarding Question 5

No, you don't have to enter anything for question 5. The maximum score you can get for the mapleta execution part is 15/16.

How do you find k for #7...

P2:

I think it should be:

The linear mass density is independent of the mass M.

There are 6 wavelengths of the standing wave fitting into the distance L.

MapleTA says that is incorrect. Where did I go wrong? Am I missing something?

For the rubber band, it stretches more with the greater weight. That means that the mass density changes with M

is there no video for this lab, i do not see one posted

PLEASE NOTE!! There are two equation (9)'s! one on page one and one on page six.Question #4: for Delta v equation (10) should not be used I used equation (9) on page one.
Question #9: for Delta v I did not use equation (5) as stated I used (9) on page six.
both answers were graded correct.

YOU FIND #7 by graphing the shit

then you gotta find the fucking slope

then you gotta put the slope in number 7 like you did for ever other fucking lab

idiot,
