4 as O2 has a double bond in between. so no of electrons = 6 - 2 = 4.

@spidey

even i thought that at first.

but if votes r 3 and 4.

the first and second runner get tied up.

A = 4 ( 40 % )

B = 3 ( 30% )

C= 3 ( 30% )

there exists a tie.

so i restorted to 50 ppl. bcoz
1. again diff of 1 vote is not possible with even nos. so 20 , 40 r out.
2.with 30, votes r 9 , 10 , 11. but %s are not integeral.
3. with 10, there is a tie..
so next no is 50.

ok. i get that. then, diffrence is 1 vote.

for miminum diff, no of ppl = 50 ( so that diff between A , B and C are least, kkeping in mind 3*(no of ppl)/10 is integer )
As loser gets 15 votes (30%), B gets 17 votes (34%), C gets 18 votes ( 36%).

[b]yup ! 2%.

just look. 70% votes are to be distributed among 2 people, both of which have got a different no of votes ( else diffrence is 0 ). so for minimal difference A gets 36% ( 70/2 + 1 ) B gets 34%.( 70/2 - 1 ), so difference is 2%.

It is :

University Physics By Sears, Zeemansky and Young

personally, i like the book, great explanation.

i am agnostic. ( belive that existence of God can not be established nor disproved, as human consciousness is limited ).

it goes unsaid i m a firm beliver in science.

Just like we can not prove God exists, there exists no no proof he does NOT exist. So the thing remains we don NOT get to any conclusion. So let the things be as they are .

Compare it with this :
i say that x^2 - x + 17 is always a prime. u can NOT simply say its FaLse. u have to give a counter example or contradiction. Here x^2 - x + 17 is composite for x = 17.

Similarily, as a proof exists for neither absence nor existence, going by the principles of science, we can NOT say anything about it. So thats it.

Well, superacids known as carborane ( CHB11R5X6 , X= halogen, R = alkly goup ) acids are known to be strongest acid, but they are non corrosive in nature.

2nd comes HSbF6 (Flouroantimonic acid ).

Note that acid strength is not measured by corrosiveness, but ease with which they split in H2O, which is measured by acidity constant.
Catalogs Discussion Forums -> Mechanics -> why is it that you need more power to pedal a flat tyre -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
7 replies   
Actually, when a tire becomes flattened, the component of rolling friction decreases but that of sliding friction increases due to higher area of contact at any instant. As kinetic frictional coefficient > rolling frictional coefficient, hence sliding friction opposes with a greater force than rolling. So total friction increases, so power req is more.

NOTE : I DONT MEAN TO SAY FRICTION AND AREA OF CONTACT ARE ANYWAY RELATED.

                  .............            eq(1)


          .......................      eq(2)


{ b x eq(1) } - { c x eq(2) }         gives



As is irrational, so ..     b2 - ac = 0        and         ab = 2c2.


So c422 = a2b2 = a3c. If c 0, 22 = a3 / bwhich is false as 4 = 22 is not a prefect cube.


So c = 0. And this means a = b = c =0.


 


Rate if i am correct.

the solution for this is a = b = c =0.


providing the soln in the next post.
