A team of engineers has decided to design a new shoe for people suffering from a painful foot condition. Which of the following tasks should the team
undertake during the process of researching the condition?
A. Find a rubber manufacturer to design the sole of the new shoe.
B. Determine how much potential consumers would be willing to pay
for this new product.

alleviation.
D. Test the shoe in a trial.

what does the table look like

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.
