Identify the type of scientific knowledge represented by each statement.
Law , theory, hypothesis
If a certain piece of metal is called it will conduct electricity better.
The amount of electric current the pass-through connector is directly proportional to the voltage and described by the formula v=IR
Electricity is the flow of electric charge in a form of electrons moving through a circuit

the correct answer would be d. hope this !

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

it is b that is the answer.

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.
