An air-filled 20-μf capacitor has a charge of 60 μc on its plates. how much energy is stored in this capacitor?

Thew energy stored in a capacitor of capacitance and voltage between the plates is

.

Substituting numerical value

a.   mass number from atomic number

  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
