Answer:
A
Explanation:
A is just the most logical. Sagittarius doesn't mean anything here.
Light does not originate anywhere. DNA is not formed in a black hole.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Answer:
explained
Explanation:
Yes, the heating of filament is what causes the light production (photon emission), and this heating is caused because of current in the light bulb
(H= i^2*R*t i=current, H= heat, t= time and R= resistance).But using constant current source is not a good idea because in constant current source resistance is very low that can cause short circuit and ultimately fusing it. Whereas in constant voltage source current adjusts itself and prevents fusing because of high resistance in the circuit.
