An ostrich runs north in a straight line for 21 meters. she then turns around and runs 25 meters back toward her nest (south) on the same path. what is her displacement?

20 drops hope this

hurricanes form in warm water

what is the question here. i think you messed up.

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.
