Temperature affects resistance. As temperature in the wire increases the ressitance increase because particals are colliding more frequently. I am not very sure about temperature being not constant as an error. When I think about it, maybe but I'm not very sure.
Until now the highest grade boundary for an A is 33 (in my knowledge, may be I'm wrong). What i know is that it can be 33 but not more than 34 if its more than 34 then it will be a nightmare for everyone!
Well thats gr8. In the last question for the assumption of resistivity i worte two points 1. Temperature may not be constant 2. Terminal velocity not reached So can any 1 of these be correct......there shouldnt be parallex error r8 coz they mentioned that our calculation is correct doesnt that mean there is no parallex error in our calculation????
It says CALCULATION is correct..... It does not say MEASUREMENTS are correct...so we can write PARALLAX errors ( i wrote parallax errors when measuring length)
Can anyone tell if we can do A2 privately after completing AS in school?
And.... What did everyone write for the critics? I wrote that few readings taken at least six and lack of accuracy in the values of length as they are in meters (not in centimeters or millimeters).

Terminal velocity is not even related to this experiment.
