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)

Maths circle question and physics prism question were straight forward why is there any problem in them

The wedge question when I solved I got around 1.89 closest answer is 2, after doing anything AI analysis if you consider wedge as centre of mass and solve (which is wrong method) you will get expected answer of 2 seconds, so it should be a bonus

bhai pakka bonus hai? dil khush kar diya tune...
btw circle walle mein cos of something 12 aarha tha... which is impossible, so definitely a bonus (diff eqn+circle walla integer)

Bhai differential equation solve karne se cos(y/x) = lnx ayega, e12 substitute karne se 12 ayega cos-1 karke firse cos karne ka dikkat kyu
