Match the term to its description. Gravitational energy
Answer 1

Mechanical energy
Answer 2

Nuclear energy
Answer 3

Thermal energy
Answer 4

Internal energy caused by vibrations of atoms and molecules
The potential energy of position
The energy of an object due to its movement
Energy stored in the nucleus of an atom

Gravitational Energy: The energy of an object due to its movement

Mechanical Energy: The potential energy of position

Nuclear Energy: internal energy caused by vibrations of atoms and molecules

Thermal Energy: Energy stored in the nucleus of an atom

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.
