can u pls help me with path difference before u go?View attachment 13014

but i can help u alittle X is da first minmum for sources S1 and S2 so it should be lamda/2
so options B nd D r off nd i dont thnk A is possible so it should be C
path differenc is S2X-S1X= Lamda/2

i think it's B, what year is it from??

 

[Soldier313]

Hey people, does anybody have a list of all the formulas we need for physics tomorrow..?
Please help urgently....thanx

its b obviosly becuase at p voltage=emf then at q its not 0 which will be the case when there would be no internal resistance
so pd would be less becuase of internal resistance,
emf=I(r+R)

ok for number 36-
at x voltage= 5/10 multiplied by 2 = 2/3
at y 10/15 multiplied by 2 =4/3
potential difference= 5-2=3
thing to notes voltge=2 on both sides as its parallel connection and you have to follow path from possitve termonal of battery for both
35- at R1 = 5-3=2 R2=3-2=1 AND R3=2-0=2
HOPE THAT HELPS

i cant see your other doubts means you have provided the link but where is your doubt can find them there

pretty sure it is A because there is already a voltage V across r so when R is connected V will decrease

Q8
answer is A because speed increases uniformly so constant acceleration

Q6 + 5

when adding or subtracting 2 quantities add absolute error
when mulitplying or dividing add percentage error
when a quantity is to the power of something multiply power to percentage error
