What are the two main factors in the mantle that contribute to the rock cycle? A. weathering and layering B. layering and pressure C. heat and weathering D. pressure and heat

i think it is true since you can test the answer and can use observations to complete it.

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.
