Light from the sun allows a solar cell to move electrons from the positive to the negative terminal, doing 2.4×10−19 j of work per electron. what is the emf of this solar cell?

The emf of the cell will be 1.5 volt  

Explanation:

We have given work done

Charge on electron that is q ,  

Energy of electron is given by , here e is charge on electron and V is emf

V = 1.5 Volt , that is emf of the cell

So the emf of the cell will be 1.5 volt

  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
