This Post 5 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]

 When it comes down to it, who we are is defined

by the choices we make.
 
Personality type, intelligence, genes, and life
circumstances all play a role in why we are
where we are in life. But within these
parameters, we have a myriad of choices
available to us.
 
Some of those choices can enhance, override, or
totally negate elements of the parameters.
There's a whole lot of power in choice -- power
for positive change and power for unpleasant
outcomes.
 
Many of the choices and decisions we make in
life, especially in our younger years, are made
from ignorance, fear, or a lack of self-
awareness. But time and experience teach us
which choices and actions lead to regret and
those that lead to happiness, fulfillment, and
peace of mind.
 
In my half-century (+) of living, here are a
few of the choices 'I've never regretted --
choices that have contributed to my happiness,
health, and overall peace of mind.
 
1. Express your real feelings even if you are
scared or uncomfortable.
 
2. Cease trying to change the significant
people in your life. Accept and love them as
they are or move on.
 
3. Acknowledge mistakes and ask for
forgiveness.
 
4. Talk to a counselor or coach when you cant
work it out yourself.
 
5. Give away the clothes you haven't worn in
the last year.
 
6. Stop gossiping about others.
 
7. Come home from work early to spend time with
your family.
 
8. Do the thing you've been dreaming about for
years.
 
9. Make exercise a non-negotiable part of your
day.
 
10. Ask for what you need from your spouse or
partner.
 
11. Give your spouse or partner what they need.
 
12. Learn a new skill every year.
 
13. Give a warm smile and a dollar to the
homeless guy on the street (even if you aren't
sure how the dollar will be spent).
 
14. Let go of a relationship that is draining
you or causing heartache.
 
15. Under-schedule rather than over-scheduling
your life.
 
16. Learn to meditate and practice meditation
regularly.
 
17. Go to bed earlier and get up earlier.
 
18. Tell the truth even when it is embarrassing
or difficult.
 
19. Spend less time in front of the computer,
television, or smart phone.
 
20. Say 'I love you' every single day.
 
21. Let go of grudges and anger as quickly as
possible. Be quick to forgive.
 
22. Take the job you love, even if it pays you
less.
 
23. Be appropriately honest with your children
at all times.
 
24. Spend less on material things so you can
afford more experiences.
 
25. Make a decision, even when you aren't sure,
rather than languishing in uncertainty.
 
26. Take a stand for something you know is
right, even if it's unpopular.
 
27. Allow yourself to be silly, goofy, and
carefree.
 
28. Care less about what others think of you.
 
29. Focus intently on the task or action at
hand and savor it fully.
 
30. Take a few moments every day to acknowledge
and reflect on the good in your life.
 
31. Say yes when you mean yes and no when you
mean no.
 
32. Plan in advance for something fun to do on
the weekend.
 
33. Spend within your means. Seek help to get
out of debt.
 
34. Plan and take the trip of a lifetime.
 
35. Become proficient with your computer.
 
36. Spend time with people in the generation
behind you and learn from them.
 
37. Clean out the clutter and unnecessary stuff
in your home.
 
38. Give up junk food and fast food, and eat
more vegetables.
 
39. Say yes when someone needs your time,
support, or a helping hand.
 
40. Make love even if you don't feel like it at
the moment you're asked.
 
41. Step outside to look at a full moon, a
shooting star, a rainbow, or a snowfall.
 
42. Play games with your family.
 
43. Offer praise to someone who deserves it,
even when you feel jealous.
 
44. Do whatever you can to change anything you
hate about your life. Exhaust all
possibilities.
 
45. Don't argue about politics or religion.
 
46. Take action in spite of fear.
 
47. Accept failure as a step in learning rather
than an end result or life sentence.
 
48. Listen to your body and intuition as guides
for changing behaviors or decisions.
 
49. Clean the dishes before you go to bed.
 
50. Drive carefully, calmly, and non-
aggressively, even if it means you'll be late.
 
51. Choose the funny movie over the violent
one.
 
52. Learn to enjoy your own company.
 
53. If you have the choice to sit it out or
dance, dance!

 man i have done a lot of research on books these are the best one's.i have almost all the books refered online.

MATHS-dont buy ml khanna(almost no theory),dont buy tmh.buy all the arihant series in mathematics(not new pattern iit mathematics) except algebra(way too much out of the syllabus).they are awesome.they contain all theory solved examples and exercises with solutions.they are 100% enough to secure very good marks.

PHYSICS-for physics buy MTG interactive physics.it has small 8 volumes.IT IS THE BEST BOOK FOR PHYSICS FOR CONCEPT BUILDING.after reading it thoroughly do problem's from hc verma.each and every one of them.and if you solve whole of them more then twice and if you still have time do problems from new pattern iit phhysics by dc pandey.thats it no irodov no krotov and nothing else.

CHEMISTRY-for organic chemistry buy a modren approach to logical organic chemistry by j singh.it has all the theory and good number of questions too.for physical all books rcm,p bahadur contains too much useless stuff.i recommend take notes of a good teacher in your city both printed study material as well as class register if you dont go to coaching.in inorganic nothing will be asked out of ncert. 

also dont forgget to solve past 34 year quesn.if you honestly do all these things no one under the gods hot sun can stop you froom going to iit.

 if f(x) and g(x) are two positive and increasing functions,then

(a) f(x)^g(x) is always increasing

(b) if  f(x)^g(x) is decreSING THEN  f(x)<1

(C) if  f(x)^g(x) is increasing,then f(x)>1

(d) if f(x)>1,then  f(x)^g(x) is increasing

This Post 25 points    (Olaaa!! Perrrfect answer.   in 5 votes )   [?]

  The Spanish have a proverb: Tomorrow is often the busiest
day of the week. Clever wordsmiths, those Spaniards.

We all procrastinate. We dawdle and delay, dally and defer.
My office floor is still home to a pile of papers that
needed filing two months ago; I'm waiting for them to stop
dallying and file themselves.

Whatever the task, whatever the excuse, the tips below will
help you do today what most people put off to next month.

1. Ask yourself, What's the holdup? People procrastinate
for many reasons. Some fear failure. Some avoid boring
jobs. Others shy away from getting tangled in a complicated
mess (i.e., my pile of papers). Knowing the cause of the
problem may open your eyes to an obvious solution.

2. Do you need to do it? Simple question, but it's a good
one. Sometimes we put something off because it's not
important. If you don't really need to do it, free yourself
of the mental burden and drop the task from your to-do
list.

3. Ask for help. I have an ancient window mechanism that
takes the effort of a drawbridge operator to open. Last
month, unsurprisingly, it broke. Someone had to fix it, but
I was hoping that someone wasn't me. So I put it off.

After weeks of gazing at the window without actually doing
anything, I asked a friend to help. It wasn't only because
I have the mechanical skills of an uncoordinated squid; I
knew it would get me moving.

4. Commit just five minutes. That's it--just 300 seconds.
Telling yourself you only have to do something for a sliver
of time does two things.

It transforms a big job into a tiny matter: Five minutes? I
can do that. And because getting started is the hardest
part, once your five minutes is up you'll often drive right
on through to the finish.

5. Focus on the end. Thinking about how you'll feel when
you've done whatever needs to be done may motivate you to
make it happen.

I don't much like to organize, but I love to be organized.
This is what I focus on--the feeling of having everything
in its place, clean and tidy--when I need to declutter a
space. Although my pile of papers proves that I have some
work to do.

6. Just do it. Quit stalling. Quit rationalizing. Stand up,
walk to the danger zone, and get to work.

  Only 10 milli amperes (0.0001 amps) through the heart is enough to kill a human.

The Mythbusters, a show on The Discovery Channel, covered this proving that an electrical appliance dropped into a bathtub, plugged into a standard 110 to 120 volt socket will provide enough current to kill a person.

Current (kind of like the speed of electricity) is the key factor. With a Tesla coil you can generate thousands of volts and it only gives you a shock like that you get when you get a static electricity shock from a doorknob. Voltage doesn't kill you it is the amperage.

Since we are mostly water we can conduct electricity pretty well so getting shocked can be serious, the difference between life and death is if you are grounded. Since a car has rubber tires if a power line falls on top of the car you will be safe; as long as you remain inside the car.

But, you can have a huge bolt of lightning go through you and still survive, if it grounds out without having to go through your heart, even then some people have had their hearts stopped and received medical attention in time to save their lives.

 since q=it

      =>dq=i(dt)

           q=

          integrating this within 0 to 8 gives q=330c minus sign because of sign of charge of electron.

for constant current i=q/t=330/8=41A

 actually thats a good question.the question you asked is of the topic functional equations.these questions are little trickier.you need to go through solved examples.i use the book diffrential calculus by amit m aggarwal and these type of questions are explained quite well in it.i reccommend it to you.dont forget to rate if it helped

 i think the among the 1st and 2nd ,2nd would be more stable because of 2 alkyl gp which increase the +I effect and third the least because it has double bond =>more s character and hence more acidity.rate if it help
