[syedaliadib]

Guys what were your answers from the last question?

 

[aziz ashfaq]

what was the experiment? I forgot

 

[aisha14]

The range of the graphs were a bit tricky, but I took 3 boxes, and that did the trick of using 80% of the graph on both axis.

 

[aisha14]

About the graph. I think, the main sources of uncertainity were parallex error. WBU, guys?

 

[Faruq Al Mahmud]

i messed up the second last question big time....wat were ur answers aisha?

 

[syedaliadib]

Parallax error or zero error

 

[aisha14]

I found many advantages but No disadvantages.

Advantages: Reaction time slow, so, less chances of human reaction error.
Use digital, so that there are less chances of systemetic errors.
