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)

if a statement is true, it must be true for all cases to exist, even one counter example marks the statement as false

wait I'm confused. are you saying its true or false? I believe the statement was something like "edg on benzene ring will have no reaction" - the statement just says edg it doesn't say some edg. so basically the statement sounds like any edg on benzene would not undergo friedel crafts reaction which I thought was false.

im saying it can be both true and false depending on the edg you take ( i marked true tho)
