JoinQuad. Eqn
Which of the 2 graphs is right?
and why?
by hit and trial i got x=45 and y=1 but i wanted to graphically confirm if it was the only possibility in N...
PnC Hit/Trial Alternative
is there a better way to do this other than putting in indivisual values of n1 n2 n3 n4 n5 and tediously finding all 💀
Stability of Carbocation
how is the meta one most stable , i was expecting ortho or para one to be most stable
PnC
in the first one they havent considered the repetition of E and N in ENDEA
i think it should be cuz like any of the 3 Es can come and so can any of the 2 Ns...
Motional EMF / Flux
in this question they just placed a emf source (metaphor for the Motional emf of rod) of value BVL but the flux is also changing for the closed loop shouldnt that also contribute to the current
Organic, mild hydrogenation confusion
The solution says A is
cis but-2-ene
But since there's no Lindlar's catalyst, A should be butane right since there's nothing to stop unrestricted hydrogenation...
induced current due to rotating non-conducting sphere
the ans they have given is 8 what have I done wrong
Algebra
in this question at last we get -8 and +16
p^2 + q^2 + 2pq = 4
P^2 + q^2 = 4 - 2pq by this logic pq cant be +16 but in ans it is why?...
Solutions, colligative property conceptual doubt
The number of moles of acetic acid here are = 45
number of moles of H2O here are = 150
We use the
Kf of water here to get the correct answer because water has more moles
But acetic acid is definitely not negligible here...
Chem: Structure of pramanu(atom)
help please tumhara din accha ho jaye reason bhi dedena( with reason plz solve this question)
Kinematics
Radius of curvature is confusing. I thought of normal accln playing role, but don't know how exactly to write. I'll claim my kinematics too weak.
R= u^2/normal accln ...whts u and a exactly 🙂...
