Bulb

Explanation:

Bulb and fluorescent tubes convert electrical energy into light energy. The best alternative in this case will be a bulb. The switch controls flow of current hence used to put the circuit on and off but doesn't do any conversion.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
