FOR EUREKA !!!!!!!IF U CAN SOLVE THESE QUESTIONS... DOPPLER EFFECT IS OVER!!!!!

no yaar thats the trick of the question the sound also takes sum time to reach the observer.......see the soln. i hav posted.......

its only ur approach that matters they hav been posted...

anyway the answers ar 1350 and 203

and for question 6

instead of solving generally at t=3

the velocities are perpendicular

so only the velocity of source comes in to the calculation i think

its so evisent luk at figure it ossilates along the diameter of the circle!!!!!!!!!

and doppler effect is applied along the line joining both the bodies !!!!!!!!!!!

for q6 there is nowhere given in the ques that the length of AB is 1200 m
Also please tell me that when we are to apply doppler's effect are we supposed to take relative motions between the points when the sound is emmited by the source and the point where the receiver receives this sound

forgive me for poor presentation...............[2][2][2][2][2][2][2][2][2][2][2][2]

many problems are like this in doppler effect..........

i feel q6 is the mother of all problems in doppler effect!!!!!!!!!

simple though!!!!!!!!!!!

[1]

no i just said that cuz ull get complex equations.... and yess its totally logical!!!!

u were saying that without calculator we cannot get these, so do we have to depend only our logic?

by the way neeche waale ban gaye. aasaan hain.

and ya please post some maths questons if u have any.

par t=3 par yehi to hoga???????

NOPE THINK OVER IT NOT THIS EASY ...... EASY THOUGH[3]

u mean logic is the base here?

HERES A PASSAGE !! GUD 1 ..... SORRY ALREADY CORRECT ANS ARE MARKED[2]
BUT DONT LUK AT IT[3]
