Answer 1

Hi friend,

The possible reason could be :

1. The bulb might be fused .
2. The cells might be dead.
3. The connections might be loose .

Answer 2

this is based on concept of electrodynamics .
bulb glow only when current passing through it . current means what ??? change in charge( e.g electrons)per unit time .
above explanation means bulb glow only when electrons moves from liquid to bulb and bulb to liquid .

here bulb doesn't glow , I think
(a) electrons are not moving across the bulb . so, potential are not developing across the bulb , hence bulb doesn't glow .

(b) may be happen that required potential doesn't devalop by system so, bulb doesn't glow .

(c) may be happen that liquid is neutral no any charge or mobility .so , current don't develop by this .

(d) filament may be gone .

(e) bulb may be fused

(f) circuit may be opened

(h) wire may be neutral ( current doesn't passing this wire
