Physics Paper 34 : Predictions and Discussion

[Herpzlord]

Hello Guys,
Let's discuss the possible question that can occur for Physics 34 practical exam. I heard that there is no electricity this time.

In physics the absolute error is equal to least count of the instrument?
And in stopwatch or mass balance do we multiply the absolute error by two?
Help would be greatly appreciated.

i think u don't have to multiply by 2, u might want to check out this note in case u haven't already seen it.

In the following questions all lengths are measured with a metre rule with the same least count; so why are the values for absolute uncertainty different in the marking schemes?

What can be the limitations and improvements of this experiment asked in p31 I suppose.....
