Post Your AS LEVEL PHYSICS PAPER 2 DOUBTS

[applepie1996]

and for example if we have to calculate the uncertainty of the reading of a metre rule. The reading is 10. least count is 0.1 then we should take out uncertainty as: 0.1/10*100 or we should halve the least count 0.05/10*100 to take out the answer. Which 1 is it /???

its the 0.05 one
hey wat variant pratical r u cuz myn r dun

In 1b) the marking scheme says to the nearest mm. My answer is 58.3. Is it to the nearest mm how do we know?

I THINK FIRST QUESTION MICROSCOPE IS FROM STEM SLIT.

ok so phase difference is 128-100=28cm this is because s1 is 100cm from M and s2 is 128cm from M u form a triangle and find the hypotenuse which is 128cm so now u find lambda = speed/frequency lambda for frequency of 1000hz=330/1000=0.33m=33cm
lambda for frequency 4000hz=330/4000=0.0825m=8.25cm
thts all i have cleared out just wait aliitle and i'll figure out the other part of the question

u've got some super Faggy profile pic change it
