u used the diameter .... use the radius..

thanks .-. that was a silly mistake.
and what about the other 2 Qs?

 

[exploded diper]

somebaady plz!

10 . b 11.
use the energy in the previous question and divide it by the latent heat of fusion to gain the mass

varient tu kiya hi ni mne

use the energy in the previous question and divide it by the latent heat of fusion to gain the mass

but why?

 

[Ram97]

but why?

cuz it says energy removed which is same as Latent heat of fusion as same amount of energy would be required to change its state

A voltage is connected across the Y-plates in the c.r.o.
State and explain the effect on the trace on the screen

divide 11400 by 5700 u will gain 2..... so after two half lifes the the atoms will decay to 2x10 20 by dividing 8.0 × 1020 two times .......
the rest left would be atoms of carbon.... substract 8.0 × 1020 by 2x 1020

electron beam will move vertically towards the positive terminal among the Y plates

the trace would bw deflected up or down....

Can i get a full picture??

 

[Fate0]

Good Luck Everyone.
So jao sab abh

 

[peacce]

the trace would bw deflected up or down....

but dont y-plates results in horizontal movemnt? i read smth like dis or m i mixing smth?

[peacce]

ihope it goes well

yeh time base cuz horizontal deflection.....

 

[peacce]

yeh time base cuz horizontal deflection.....

Acha so for Electron flow, we use left hand rule right? And for conventional/proton flow, we reverse the direction?

Is it C

 

[exploded diper]

no its the opposite.......electon ke liya left hand rule mein current ki direction reverse karni hoti hai....
