Natasha measures the masses of three objects and records her results in the table. What should Natasha do next to determine the densities of the objects?
She should measure the circumference of each object
She should measure the temperature of each object.
She should measure the volume of each object.
She should measure the surface area of each object.

what are the choices?

lol idk man i guess u gotta ask bill nye the science guy

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.
