if the mass if an unknown substance is 5.3 grams and the volume is 2 cm 3 what would be its density (round to the nearest tenth)

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

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.
