Umm. Hey guys!
Okay so I've been solving past papers, and you know the questions about the measuring x or h or whatever, well I measured that with my ruler, and when i checked in the marking scheme, it used to have an answer near to that but never the same. So will i be penalized in tomorrow's exam? Also the marking scheme doesnt really mention the uncertainties. And every past paper has a question which asks us to measure the length of a line. :/

Don't worry about that, it's just when you print them out they get resized.
In the real thing they dont get resized.

Your printout or photocopy just had a magnification larger or smaller than the actual booklet.
In the real thing tomorrow, all booklets will be the same.
Printing or photocopying edits the size. Not to worry.

Hey, this has been asked a lot of times here already. As you aren't solving the original paper differences in readings occur and that's why you are getting a slightly different answers! This will not be the case in the exam tomorrow as each student will have the original copy. Plus, I don't think they penalise for small differences so don't worry.

It IS balanced before placing the Load Q..After u plave the load the rule gets tilted

@ VIN : Read the question properly, it said "Load Q is placed carefully on the balenced metre rule"...

the rule is still balanced.
