When Truman walks across the tile floor in his kitchen, the sound of his shoes is loud and sharp. Which of the following best describes what would happen if he walked over carpet in the same shoes?

explanation:

i think option no d is the correct answer

it is the most commonly accepted one

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.
