As per the question we are asked to calculate the average power produced by flashlight.
It is given that the voltage [V] = 12 volts.
The current flowing through the circuit [I]
The power consumed in an electrical circuit is the product of voltage and current flowing through that circuit. Mathematically it can be written as -
power = voltage×current
i.e P = VI [here p is the power]
Putting the values of V and I the power is calculated to be-
Here watt is the unit of electric power.

I hope this helps you!

A line that's 'normal' to the surface is perpendicular to the surface.
The angle of incidence is the angle between the normal and the light ray ARRIVING at the surface.
The angle of reflection is the angle between the normal and the light ray LEAVING the surface after it's reflected.
The law of reflection says these two angles are equal.
Copper is a chemical element having atomic number 29 and represented by the symbol Cu.
The electron configuration of copper is 1s2 2s2 2p6 3s2 3p6 4s1 3d10 and copper will share one atom from s orbital as it can hold two electrons and form one bond with other atoms to become stable.
