I have a dbt i was deriving result and got that Delta T=lemda g delta H only when theta2=±theta1
I think this is possible only when delta H=0 which doesn't make the result sensible...

Resonance

Our teacher thought us concept of counter resonance that it is very unstable (its resonance when 2 different electron density region trying to get stabalised from same pi bond of vacant orbital or something so they counter each other and thats very unstable) But then HNO3 has equivalent resonance but NO3- also has counter resonance so is not HNO3 should have higher resonance energy Also one more dbt why does HNO3 dont have intra H bond...

Prove reflection property of parabola by vectors (like in optics we find reflected light vector) i got confused btw someone think it once

Organic Resonance Doubt

Which one is more stable and why? My reasoning is is ch3 is bulky hence the o is more electron negative and would be more withdrawing the electrons from the benzene ring...

parabola

The co-ordinates of focus of a parabola which touches x = 0, y = 0, x + y = 1 and y = x - 2 are a)3/5,9/5 b)6/5,2/5 c) 1/3,1 d)2/5,1...

for part a) why cant we just say it would be sqrt(4g/l) as we derived in wpe that min vel to complete a circle for a rod is sqrt(4gl)
