Hey come and discuss your questions and answers........

Hey all IITians.......

Chat here with all ur friends who r online........

enjoy this..........

It is very difficult to identify nudges.......

so enjoy this.......

In transformrs I₁/I₂₌emf₂/emf₁=no.of turns₂/no.of turns₁

By using this, can we get more current or mor emf by using emf which we get in our homes.....

If we can......why we are not doing this??????

h=(u^2)/2gby substituting this value in other equations u can get what do u want

please reply meeeeeeeeeeeeeeeeeeeee

aldehydes which lack an alpha hydrogen when heated with conc. NaOH undergo a disproportion reaction. One half of aldehyde molecules oxidise to carboxilic molecules oxidise to carboxilic acids and another half reduces to an alcohols.HCHO+NaOH --heat----> CH3OH+HCOO-Na+

It is expected that basic nature of amines is

tertiary>primry>secondary......But it is

secondary>primary>tertiary>NH3

it is because stirric factor of tertiary amine ie thar crowding of nitrojen atom from all from all sides by alkyl groups makes the approch bonding by a proton or electrophy relatively difficult..the max sterric strain results in the tertiary amine.

Here is a outstnding book for physics download this...........

( permittivity of free space)(no. of turns)^2(area of the one turn of solenoid)(relative permeability)/(length of the solenoid)

It may useful to u

|.....................north pole downward......................|

north, north poles repels, doesnt exist any attraction force

|~~~~~~~~~~north pole upward~~~~~~~~~~~|

|..................................................................................|

in the space between two magnets north north poles of two magnets repels...........if we fix both magnets by placing them in close as they cant move.......they always try to escape from each other.......now if we place any object which has less mass............it floats in air...............both magnets are very huge(very high magnetic fields)

this is my thought...........

give me reason.....why u suppose or oppose me.........

See this.....dont laugh if u feel its funny.....

if we put two heavy magnets, will gravitation between them become zero.....

i heard that magnetic field opposes gravitaional field........

so pleas answer me...............

k thanxx

But it is not much effective

Thank u .(2296)......Will try to make that

Give me reply.........plzzzzzzz...........

I want to exibit that project in workshop. So I have to make a small chamber. Plz tell me the prosedure to create that small chamber.......

But magicians can make things to be float in air. How do they do like that.....what is the trick..it doesn't mean that they are making gravitaitonal zero. But what concept they are using???

Cant we create a place where Gravitational field doesn't exist? If it possible please answer me..

Does heat continuesly produce in our body?
