Answer pls guys...............

Nice reasoning mascot...

If the sun becomes twice as hot

A.the output of radiated energy will be 8 times larger.

B.the output of radiated energy will be 8 times smaller

C.it will radiate predominantly in infra red

D. It will radiate predominantly in ultra violet.

Pls give reason and answer

No idea what to say yaar........

It is a major debate Jain... U can't say that it's all natural...Man certainly has had a say... True u can say that it's all a part of our natural climate cycle... but we never know...

Cheers

Nice One..

One correctn... Tendency to form peroxides inc. down the grp in grp I.

But in K and below the tendency is more to form superoxides b'coz of even larger size. Why not Ca then??? It is the one nearest to Na in size.

I'm just askng b'coz i still have doubts abt the questn. It was asked to us in a test,and no one is sure of the answer...Imagine that.........

Well guys, when we displace a body or compress a spring, we give it some energy. The principle of conserv. of enrgy prohibits loss of this enrgy. This enrgy is stored in the body as the potential energy. Potential energy occurs mainly when a force acts on a body trying to change its postn. When displacing a body to a height the force of gravity tries to restore the body back to the grnd. In a strchd sprng the restoring force acts .

Kinetic enrgy is energy in action. Whenever we extrct the potential energy of a body, it first turns into kinetic enery and then only can we use it.

Cheerio guys.

Gr8 ans pranav.

Thanx man

Thanx for the ans. But i don't quite get it yet...

K is defined as the force req. to stretch the string by a unit length, right?
Then k*l ill mean F right? Pls explain again...

Hey guys... On cutting a spring of force constant k into two equal parts, the force constant of each part b'comes 2k. Why so???

Grt ans. Arnav... But a Prof. of ours told me that the answer is Be. But he could have been wrng.

Ur reasoning is superb........!!!!!!!!!!

Hey guys can anyone tell me why grp II usually form only the monoxides?

Hey ronaldooo... well actually, i think that there is an exception o the rule
mi*m2=-1. This exception applies when the two lines are parallel to the two axes... I'm not makin this up. I b'live it is so am just not a 100% sure.

If this is not right. i will go with Budokai ...

Dude............How can n be greater than infinity?????????
