i think u forgot to mention which direction as block is com,ing down so biiger block will move towards right
|
|
|
|
|
actually its easy here along hjorizontal external force is zero .so cm will not move along x axis akkis rit its probably given in hc verma example
|
|
|
|
|
sorry vignesh i think u r wrong in ur calculation it is coming 3/80 not 3/40 u missed the 200 in the denomiantor
|
|
|
|
now for concentration actually refers to strength in grams per liter=normality *equivalent wt =0.0325*36.5=1.18625gm\l
i think i am correct

im getting 0.0375m i did using law of equivalents at first :
equivalents of hcl=0.1*0.2=0.02
equivalents of naoh=0.5/40=0.0125
now it is obvius taht hcl is in excess so number of equivalents of naoh =no of equivalents of hcl that reacted
so equivalents of hcl unreacted =0.02-0.0125=0.0075
thus normality of remaining hcl=molarity og remaining hcl=0.0075/2=0.0375 plzz corr3ect if ne mistake is there

ive just a question can we generalise it coz see in rolling in horizontal we may have either forward rolling or rolling with backward slipping then question should be specific
|
|
|
|
|
actually int thse rolling motion cases u just need to see the point of contact has tendency to slip inwhich direction friction will be in the opposite direction to help in pure rolling
|
|
|
|
|
absolutely rit it is flourine from pauling sacle itself find it and neon is a noble gas having no tendency at all to gain electrons so no question this was a very basic explanation rate if satisfied
|
|
|
|
|
first of all try out hc verma very good book and then after getting ur concepts rit u may do irodov and ss krotov
|
|
|
|

i gave it when i was in x now im in x1 u wanna know the nudge me fortunately i managed a good rank too

dipole moments are in the order hf>h20>h2s second question not too sure but it seems adduct of nh3 and bh3 each is sp3 hybridised and first one seems csf as accpording to fajans rule it is contradictory as covalency is favoured by large anion and small cation here opposite case so . ...

it si given in s block elents check it out i thnk it si correct

i think its li (aq)+ as its hydartion radii is maximum tas why ihydration energy of these compounds are also more so more soluble

loney is ggood and also hall and knight im doing them but tat before mah tests in coaching at a fst rate (not solved all).tmh is terrific and kc sinha i do them on a serial wise basis
