0.7 is a bit high....
damn it.....what was urs tho?
if u also say 0.5 am going to cry...
Well minus the part where i divide my values by 5.6x10^-3 (my value (also i used cm)) i got 0.42
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%
I took (2 / 13) * 100
Also, the questions where they said measure the length.. i wrote in the line ( 40 cm = 0.400 m ) is it fine
I used cm but got a gradient above 80...the x axis values were very low that's why maybe
Is 3° fine instead of 2?
I guess so
In the error and improvement part, is writing " large uncertainty in the value of A " as an error and " use a thinner string " as improvement correct ?
I got my gradient as 0.652 and y intercept as - 0.165
i took my uncertainty for the protractor to be 0.5degrees (the school supplied us with a really big compass) so i took 0.5*14.5(my A) and then ANS/14.5 x 100 and got 5%
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
Yea even I sued 5%
Anyone knows material for paper 22 biology
No problem fam, and unfortunately no idea about chem cuz i dropped it, plus our variant is 34 for chem anyways :/
Here is the m18 paper
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.
