1NSEP was not so easy as i expected but still hmmm lets seee
and the answer for 17 i felt it was c.
i may be wrong
what do u think guyz???
21it is b..because v= w*r not r*v
and w= d(vector theta)/dt (we know that small angular displacement is a vector quantity..)
a(r) = w*v ( w is upward..v is tangential, and a (r) along radial direction..)

Resonance solutions some errors
42) answer abd
36 answer c
25 answer b
most probably i am getting above 100 in any case 110 above out of 180 so i am in (sorry man but for a tenther its an achievement)
1what is bonus??? and 25 and 36 ka D hi hoga na!! and i am also getting somewhere around 122-130 for part A depending on 25 and 36 and 42 ka A,B,C,D hona chahiye na because why do stars twinkle??? light moves continuosly from rarer to denser medium thereby suffering refraction at each layer which causes intermittent light flow to reach our eyes giving a twinkling effect
1speed of sound depends on density of air na v = sqrt ( Y*P /d) where Y is adiabatic exponent , refractive index is reson for (c) not (b)
1remember there is no relation between density of a substance and its refractive index
turpentine and water
1u wait till 3rd dec... u 'll get it in the iapt official site

1I got selected . hey varun yaar you are in 10th no need to feel like that!
