i = cospi/2 + i*sinpi/2 i^1/2 = cis(2npi + pi/2)^1/2 put n = 0 and n = 1

'Little girl and her father were crossing a bridge.
The father was kind of scared so he asked his little daughter,
'Sweetheart, please hold my hand so that you don't fall into the river.'
The little girl said, 'No, Dad. You hold my hand.'
'What's the difference?' Asked the puzzled father.
'There's a big difference,' replied the little girl.

'If I hold your hand and something happens to me,
chances are that I may let your hand go.
But if you hold my hand, I know for sure that no matter what happens,
you will never let my hand go.'

In any relationship, the essence of trust is not in its bind, but in its bond.

So hold the hand of the person who like you
Rather than expecting them to hold yours...
This message is too short......but carries a lot of Feelings.

threshold energy - average energy = activation energy activation energy is the minimun extra energy required for active collision or to reach threshold energy from their average energy..

l = comman chord

try by taking s3 = s1 + lamda l

radical axis is the comman chord of the two circles... find the pt of intersection of radical axis and one of the circle then find the equation of circle by diameter form..

divide both sides by root2... 1/root2 = sinpi/4 = cospi/4sinpi/4 cosx - cospi/4 sinx = 1/root2

use k = 2.303/t log( a/a-x)a = 100 , a-x = 60

during ice phase of water , hydrogen bonds forms cage like structure . hence it occupies large volume, as temperature increases to 277K hydrogen bonds r broken hence volume decreases and density increases.. when temperature increases further molucular repulsion increases and hence volume..therefore water has it's maximum density at 277 K..

no of equivalents of solute per 1 dm^3 or 1 litre of solution

p^2/2m = K.E

nice one..

As I was passing the elephants, I suddenly stopped, confused by the fact that these huge creatures were being held by only a small rope tied to their front leg. No chains, no cages. It was obvious that the elephants could, at anytime, break away from their bonds but for some reason, they did not. I saw a trainer near by and asked why these beautiful, magnificent animals just stood there and made no attempt to get away. "Well," he said, "when they are very young and much smaller we use the same size rope to tie them and, at that age, it's enough to hold them. As they grow up, they are conditioned to believe they cannot break away. They believe the rope can still hold them, so they never try to break free.

I was amazed. These animals could at any time break free from their bonds but because they believed they couldn't, they were stuck right where they were. Like the elephants, how many of us go through life hanging onto a belief that we cannot do something, simply because we failed at it once before?

the volume of 0.2N base required to completely react with 0.5 litre of 0.1 N acid is

volume of acid?....N1V1 = N2V2

thanks...

yeah it's nugorama's article.....

nice one..
