Btw guys....what were ur answers for gradient and Y-intercept? (i got gradient as 0.7 while my classmates got it as 0.5 and I got my Y-intercept to be 0.06 by using the formula and not the graph, hopefully, that's fine). And for your K question...i got 7.8% meaning they are related, right? and for improvement, one of my points were "2 values of K aren't enough to make a valid conclusion " and improvement was " take more than 2 values and plot a graph". Are my answers fine?
0.7 is a bit high....

the question asked about percentage uncertainty not absolute...my answer was exactly 5%. BTW guys is it fine if i have spelling mistakes in my errors and improvements?
I'm asking for the absolute uncertainty to get an idea of the %age uncertainty bqz that depends on our working only if the a.u is correct...I took it as 3°, divided by 12 x 100= 25%

Well minus the part where i divide my values by 5.6x10^-3 (my value (also i used cm)) i got 0.42
hope the difference between my answer and urs is because of differences in our circuits :'( cuz my classmates too got 0.5-0.6ish idk about my teacher

Guys I sat for phy p33 today and unconciously I made a blunder . i didnt read the Q2 properly about that angle must be approx 14 and wrote 9° and carried Out my further calculations but my readings for Time were almost similar to others who had done it right.So are there any chances of ECF or how many Marks Would I lose ? Furthermore i think that T was not for a single oscillation because it stated That T is the time gor Number of oscillations You take , so anyone could help me out with those these issues. would Be very grateful.
