Danny's rite...Go to display properties and change the resolution. Or u'll find a control somewhere to rotate ur screen...(not joking)

@sboosy...Thanx ...didn't see ur reply when i posted mine.....

@allamraju...OK Thanx man...

and it's not Abraham...it's Abram..:P

@sboosy
Why the multiplication by three? Didn't get that part...Can u pls expln?

Let n be the number of drops...Then their total surface area is 4n $\Pi$ r2. And their total volume will 4/3*n $\Pi$ r3. The volume of the larger drop will also be the same...if its radius is R, we have.

4/3 $\Pi$ R3=n4/3 $\Pi$ r3. --> R³=nr³

The energy released by the decrease in the total surface area causes the rise in temperature.

Energy(E)=surface tension *decrease in area=t*(4n $\Pi$ r² -4 $\Pi$ R² )

Rise in temp=E/(4/3 $\Pi$ R³ $\rho$ *c)

Pls rate if satisfactory...

Cheerio

Trunks dudes is the coolest...and of course Goku has no match...

Yes..and then agn..love can inspire u to do well...

It is definitely possible to go forward with studies even when u have a love life to attend to... But it is not advisable... Love can create problems frm which we may nevr recover. We r all still young and very impressionable... ciccumstances can have profound influence on the persons we grow into...amd love causes plenty of BAD CIRCUMS...

For a body at rest... contact force is not greater than the normal force.
(A) seems to be the rite answer...Can u pls expln Rathin?

Why don't u post the prob. online yaar?

The reason is that when water falls out of the bob, the centre of mass of the bob lowers( thnk... at frst the CM is at the centre of the sphere. as watr falls there is more concentratn of mass at the lower part). After all the watr has fallen down, the CM rises agn to the centre of the sphere.

As the length of the pendulum is calculated frm the point of suspensn to the CM of the bob... the length first increases and then decreases back to the original...and also t dir. proportnl to l...so first T inc. and then dec and b'comes constant.

Hope this explns it...

@Mandy
Dude...hand it to to... I've ransacked half of the net with few results...

Can someone pls give the energy level for the 3rd shell in the MO theory?

@Karthik...pls expln dude..

MO theory.

U use the energy order of the species with fourteen electrns

The defn of a hyperbola states that the difference of the distances frm two fixed points is const. That is why the locus is a hyperbola. If u want the eqtn, use distance formula .
