Why is it important to dispose of wastes from nuclear power plants carefully? a) the wastes cause the greenhouse effect. b) the wastes are radioactive and could cause cancer. c) the wastes do not decompose and take up a lot of space. d) the wastes flow into ponds and lakes and cause algal bloom.

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.
