Answer:

A visible streak of light that shows the path of a rocky object which has entered Earth’s atmosphere is Meteor.

Explanation:

Meteors are the dust and ice originated from the trails of comets. They are the rocks present in the space, the visible bright streak is not from the rock, rather from the glowing hot air because of the hot rock zips from the atmosphere. When large number of the meteoroids strikes the Earth at one time is called meteor shower. It is the open- source isomorphic rocks. These are visible from the one point in the dark sky. These happens due to the masses of cosmic debris known as meteoroids which are coming inside the Earth's atmosphere at extremely great speed on parallel trajectories.    

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.
