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...

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 🙂...
heat transfer
i have a few problems with the question.
1. "thermal conductivity is high " means majority of the heat is conducted and very low amount is absorbed and therfore emitted so how can we find out change of temp of A .
2. temp between the surfaces of A and B is to be taken 0K ??
3. masses are not given so how can we find out rate of change of temp...
NLM
isme the acceleration of block is coming out to be 2g/3 , or acceleration wrt to wedge is 2g/3 cuz if its wrt to ground the answer should be like net acceleration because block has two accelerations one on the left and one along the incline?
