News on physics practical 34
DO NOT confuse urself! The top scale has smallest division (smallest line) equal to 1 millimeter. The lower smaller scale has the smallest division (line) written on it which is usually 0.02 mm. So the least count of this device is 0.02 mm and half of it is 0.01 mm. -

0.01 millimeters! The top scale has a smallest reading of 1 millimeter, and the lower one (written on it) is usually 0.02 mm. So uncertainty half the smallest division, 0.02 mm /2 = 0.01 mm -

AS Physics Practical - Paper 34
I don't think any paper has the same questions. So practice all possible ways.. -

AS Physics Practical - Paper 34
I'm afraid that a question related to balancing a rule will come :( These questions are irritating... -
AS level bio
They will indirectly say, prepare the space below for the results of your experiment.. -
AS Biology P34 Guesses
That's what I also said, but according to common sense, you do as follows: Find the least count of the measuring device you're using, half of the least count is the minimum (1 measurement) uncertainty of that device. Leave the rest for CIE :D -

Maybe the least count of the ruler is different.. Cause it says use the transparent ruler, not your ruler. (still maybe wrong..) -
AS Biology P34 Guesses
Least count of ruler: 0.1 cm = 1 mm Minimum error (uncertainty) of ruler therefore is 0.1/2 = 0.05 cm or 0.5 mm To find percentage uncertainty of the measurement taken by a ruler, depending on how many times u have taken a measurement, add the uncertainty (0.05) and divide the total uncertainty... -
AS Physics Practical - Paper 34
JJ, we're discussing variant 34, not just any paper 3! -- I'm also confirming, there is no electricity (I heard it). -

Making different concentrations (the table) means dilution :)
