Which best defines the relationship between speed and velocity? -Speed is velocity with displacement.
-Velocity is speed with displacement.
-Speed is based on a specific direction.
-Velocity is based on distance.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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.
