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..

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

sorry, i'm not sure why the website did not show up...here i'll try again:

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

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......

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

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

how do you get the period?

For period you do T2-T1/# of waves you counted

heyy any1 know how to find the error of frequency?? thanks

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!

How can I find the error for T(period)?

is anyone else having trouble with the period? im doing my T2-T1 value divided by 5 and it marks it as wrong? am i doin somthin wrong becuz that has to be rite

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!!
