The field lines around one end of a bar magnet are shown below.
Based on the diagram, what can you conclude about the
pole of the magnet?
Onis a south pole because the field lines spread out
from this end.
O t is a north pole because the field lines spread out
O Itis a south pole because the field lines enter the
OIt is a north pole because the field lines enter the

magnet at this end.

0.88m hope i am correct : )

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.
