How do fronts affect the formation of tornadoes? A. Tornadoes can form when two fronts move into each other.
B. Tornadoes can form when two fronts pass one another.
C. Tornadoes form when one front reverses direction.
D. Tornadoes form when one corny moves in a circular direction

answer carbon and three oxygen atoms;

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
