lab 2 help
anyone know how to find the battery voltage for the first part of question 3? i can help with any of the other questions..

Lab 2 #3
Use the animation tutorial from the following website to show you how to calculate the values. As for the units, it should be V for Volts and s for seconds and these units will ONLY be marked correct when the values are correct. MapleTA does not grade the units and values separately!
Good Luck

idk why its not working just type in 'voltage on an oscilloscope' on google and click on the 5th link by wisconline

1) Voltage, Time
2)A=1 B=4 c=3 d=5 g=6 h=2
3)
4)sqrt(deltaV_high^2+deltaV_low^2)
5)
6)sqrt(deltat_L^2+deltat_R^2)
7)deltaT_N/N

For 3 and 5 watch the lab video and pay attention to sara, it is hard to explain how to do the voltage......

Questions 3 and 5
I tried the website and i don't seem to understand it. Does anyone have the answers for 3 and 5? Much appreciated

reading # 3 and 5
reading the graphs are pretty easy, the y axis is volts and the x axis is time, but the value for each division of the axis are changeable, in the question it tells you what each division is set at, the rest is just counting, so if the y division is set for 3 volts and the x division is set for 1 s, a rectangle 3 boxes high by 2 boxes wide would be 9 volts over 2 seconds.... i hope that helps, if not watch the video cause she explains it pretty well

For period you do T2T1/# of waves you counted

Error of the Frequency
To get the error of the frequency you:
divide the T(period) error by the T(period) value. then multiply by the Frequency value. tada!

is anyone else having trouble with the period? im doing my T2T1 value divided by 5 and it marks it as wrong? am i doin somthin wrong becuz that has to be rite

Prep Quiz 3, 5
Here's my issue:
3. I've gone through the videos... and I thought I understood what she was doing when she was calculating but I'm at a complete lost. I'm having several issues  I think my counting is off, is there anyway to explain how to retrieve the values. Also, it keeps marking my units wrong, is isnt the voltage in V and the time in s?
5. I'm not even sure how to approach this problem...
Please help!!
oh physics!!

I got number 3!!
oh hot dayum!!
Okay. So for number three, just count the boxes literally and multiply by what your scale is.
For example. My scale was .5V and 1s. I counted my height of boxes (which I estimated) to be about 2.75V and multiplied by .5 and then for 1.375. Then I count my width which was 1 box, and got 1 for the time.
My guess for the units where correct the first time around.
Voltage in V and time in s. They wont mark it correct unless the whole answer is correct.
YAY!! Now I'm off to solve number 5. I'll keep ya'll posted!!

Number 5
So the first two answers are easy...
All you do once again is count boxes. 3 boxes would equal an amplitude of 3V and 6 boxes, 6V...
But the period is what I'm suck on. Arghhh!, I was so close.
Previous posts say to do T2T1/# of waves... but its not working for me. Or at least I cant figure out the number of waves. My wave is Vshaped.
So I thought Id be 63 = 3
and then 3/1= 3s
But thats not working.
Please help
Also, isn't s the unit for period?

error of Period T
hey guys, i know that someone mentioned getting the error of frequency but it also required knowing how to get the error of T, the Period
please help on this one
i can't seem to get it, i'm not sure what values to be using for expression 8.. why does it matter if n = 1 if the expression calls for the absolute value, and why is this formula given when there is no exponent involved, ect. o.o
thank you

Re: lab 2 help
so for question 5 on the lab in order to find the period....number ur horizontal line with the intervals...my increments were in 50s...so the second peak was at 400 and the 1st peak was at 100...400100=300
300*1E6=3E4s
hope this helps!! =)
300*1E6=3E4s
hope this helps!! =)

How do you find the error for the Period (T) and Frequency?? I cant seem to get it!! Please help..

Excel help
does anyone know how to get the errors for Period and Frequency? it's the last 2 boxes on the sheet.
thank you!
thank you!
ahhh Guest
Re: lab 2 help
to find the period, count up the number of intervals (each interval is one box), I had six boxes. Each box is 50 micro seconds. You multiply the number of boxes by 50, then multiply that number by 10^6 to convert to seconds.
I had 6 boxes, so that equals 300 microseconds. Then 300 x 10^6 = 3E4. Hope that helps.
