wat was required was 2nd point only
bdw wats monstrosity..??

hugeness

weak magnetic field lines means weak magnetic field there thus weaker force or propulsion weak enuff tht it cant push the compass needle thus compass would show no magnetic field there (it will point likely as south seeking pole and north seeking pole on earth)

I know

some guy in other thread is arguing that heat is not transferred by electrons in metals..:S

He needs a wedgie

 

[MustafaMotani]

He needs a vege

xD

 

[Spidey21]

He needs a vegie

actually you do cuz he is right
cuz heat is only transfered cuz of Conduction and Radiation
not Convection!!

 

[syed1995]

How can someone prevent heat from transferring via radiation??

 

[M Haseeb Javed]

2 B which part??

the gas identification

WAT??? heat IS transferred due to the movement of the free elecrons as they move and transfer their kinetic energy to the next electron and so on....
and if what u say is true and it is NOT b/c of electrons then explain y heat is only transfered (best) by metals [which have free electrons] and not by insulators like wood [which do not have free electrons] ??
