Physics: Post your doubts here!

nice nice how did you sketch the voltage for induction graph?

well i got it wrong
so ill get 3/4 since both peaks were post to be in same direction

yar i drew the peaks in same direction as well but everyone saying that they were in opp direction

i see, this paper did not have electricity or attenuation which is great

 

[anastasia grey113]

Someone please write down the marks for each question.

well i wish i remembered
but like ok ik the first question's
1 mark for 1st part line of field
3 for the second abt earth's g
4 for rock's v

yar i drew the peaks in both direction as well but everyone saying that they were in opp direction

peaks were in the same direction since both gradiants were negative

idk but like i drew with one downwards and one upwards
this was wrong

yh true
i thought of it but then i thought i was just being dumb -.-

i swear by night i will be overthinking to the point that i probably missed some question, lol it happens after every exam

Lol today 3 mins were left and it was then i just realised that i had skipped the velocity accelerator question.

ok what the hell is the correct definition for magnetic flux linkage?

 

[anastasia grey113]

ok what the hell is the correct definition for magnetic flux linkage?

just write NBACostheta and explain each symbol

what was the energy for capacitor with 3u

 

[haithsoul]

ok thank god, what about capacitors in parallel?

 

[haithsoul]

9

what was the energy for capacitor with 3u

9.6 was the charge

 

[anastasia grey113]

what was the energy for capacitor with 3u

1.54 x 10^-6 i think?

ok thank god, what about capacitors in parallel?

wut bout it?

[Zaki ali asghar]

the volts across 3u were 3.2 right?

 

[anastasia grey113]

the volts across 3u were 3.2 right?

y did u nee that?

 

[haithsoul]

yh

i defined capacitance then described what happens to it in parallel that is the total is their sum and V is the same

 

[Zaki ali asghar]

1/2CV^@

 

[haithsoul]

the volts across 3u were 3.2 right?

you could have used the charges as they are the same in series
