its a piece of equipment used to ensure that the apparatus is vertical by ensuring the angle between the apparatus and the table is 90 degrees , i think for that specific question you could have gone into more detail by saying that you ensured that the stand and bench were both 90 degrees to each other by using a set square.

no, but in one mark scheme they'd written it as "cos(Q/2(°))" so there was a unit for the Q/2 part, but not for the actual column.

Ummm can u ppl plz find  a list Of errors limitations and Dere solutions....

I need the very same info.

Errors, accuracies about protectors and stuff other than parallax error

lol, protectors  :P

dude, just go over the ones in previous past papers. i just did, and i came to one conclusion: examiners are *censored* schizophrenic.
sometimes they say you get marks for something, and others it's like "no credit given".... yep, schizos.  >:[

rofl its my phone's autocorrect. (iPhone bleh)

Dude I still want like main errors possible with protactors and stuff cuz like all I know is we need to clamp it foe better results as it is in air or some sh*t. Help :(

ah yeah, out of all the past papers only one error/improvement thingie was about protractors. the one with the bottle and measuring the angle? it's similar to the one we had in may/june.
but yeah, it only said that you can use a clamp to hold the protractor still (you get no credit for saying "a clamp to hold the BOTTLE" though) because it's hard to keep it steady while holding the bottle as well.
other than that, i'm just as clueless as you are  :'(

Then I guess we are in the same boat.
