3G 1B = 50
4G 0B = 5 ...
PnC
for first case it is same as mine but for second case ,i did
7C5 to select 5 members from Y , then 5! to map those 5 members , then the remaming 2 have 5 x5
so 7C5 x 5! x5 x 5 but i am not getting ans...
Amines/Elimination
After MeI makes N(Me)3+, shouldn't there be E1cb reaction to form (3)?
Answer:(2)...
Kinematics Doubt
in this problem, why can't we take the height as 2 m while calculating the time of flight for finding umin?
If the take height as 2m then time of flight increases, which overall decreases the horizontal velocity...
Binomial
m = 1 (smallest +ve int)
if we put it in the last line we can club them again and hence n comes out to be 0 , but why isnt he clubbing , he started solving and ans is not n =0...
Kinetics
how do i find R in terms of Rt
R = rotaion
At a time t = rotation of Sucrose = R0 - R
i cant find R in terms of Rt as we do in pressure rate law...
SHM, time period of spring system
I guess I'm having trouble in the geometry? Not sure. How do we find K_equivalent?
Ans is 2pi * sqrt(m/2K)...
Respiration
It says 'of isocitrate', so why do they consider the decarboxylation of alpha-ketoglutaric acid, just because it comes after isocitrate? Most the coaching answer keys say it's option B, but I checked the official key and it's option C. Sometimes I have trouble understanding NTA's brand of logic. Should we apply this understanding of the term to future questions?
