I got 7.14
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
