    I've attached a pdf containing all the experiments that you need to know. Although I find that learning the experiments from past papers is much better, because the information in the pdf is very vague imo.

    how do u find the uncertainty of a specific instrument? or are there standard values for each one of them? if so could you list them!!!!

    Ok there isnt uncertainty in apparatus its in the reading so for example if u measured 50cm using a metre rule (precision 0.1cm these are fixed values for different appratus look them up) so if u have to calculate percentage uncertainty u would do 0.1/50 multiplied by 100% to get %age uncertainty hope this helps if i said sth wrong others plz help

    usually in the exam you have to state it as 1mm
