Biology; Chemistry; Physics: Post your doubts here!

Solid does not even condut, written clearly in book. How can the bulb even light? :/

look the rest can never b the answers so this leaves us with no other choice .. now wot logic the britons hav used..m clueless :O

Since amd has answered question 14, i will answer question 8
Who said electricity can be conducted in ionic compounds in the solid state. CIE at least in every paper asks this question;
Why is electricity conducted in aqueous NaCl and not in solid NaCl
The ans is liquid mercury

Calm down.
Mercury is a metal, it conducts electricity.

q8 mei least bright pocha hai tab hi solid hoga :O

well, for Q 8, all i can guess is, all the other 3 are v good conductors of electricity. The bulb will light bright, so only option left is B :/

Exactly. But still this is very irritating. :/

lets ask our elder siblings

I don't have any

 

[***amd***]

ok, so now, another logic....
the ask which bulb will be least bright, they dont say which bulb will *glow* least brightly.
so, if a bulb wont glow, it will of course be least bright. no?

xplain pls ITS A

yeh kaunsi logic hai

 

[***amd***]

yeh kaunsi logic hai

jon si nazar aa rahi hai

xplain pls ITS A

C?

 

[peacce]

yeh A kese?

 

[peacce]

ar

C?

aray A hai A

 

[peacce]

C?

i chose C too ghlt tha

 

[M.Omar]

xplain pls ITS A

Don't study bio but it,s pretty clear tht is,s A.
Biomass refers to biological mass(ta-dah)
So naturally we have the trees having highest mass and then in descending order upwards.Just look for tht pattern,and it wud be A
