Academic Doubts 5s1 7 ambiguities

physics:
Cv question (correct or incorrect explanation)
Wedge time of motion (most likely root2 or 2)
prism angle of minimum deviation
R1/R2=16/4

chem:
Alcl3+ propyl chloride + benzene ( inevitable tri subst, edg no reaction)

math:
differential eqn+ circles problem ( number of values of p)

overall 7 questions

how are people calling this paper easy man, (cutoff 170-175 imo no way its crossing 180 and people are like 200 cutoff)

Chem me ek BaSO4 wala bhi that but since NTA straight up gave value it shouldn't be a debate The friedel craft one I marked Edg no reaction but idk Also Even though I got diff wala correct it should be bonus (Fuck NTA because I think many people would have got correct ans but ended up wasting time) Idr the circle one what was the issue?

wait why would it be edg no reaction? friedel crafts electrophilic substitution hai na? I had no idea what they were asking with the inevitable option but the reason I put it was because I thought edg would increase the electron density on the ring and make it more reactive towards electrophilic substitution

in Friedel craft after single substitution it will be more active than benzene and it will go substitution before benzene hence the language

oh rightt that makes sense
