With efficiency of 80%, the machine outputs 50000 J. The input to the machine should represent 100%.
If
80% --- 50000 J
100% --- ?? J
Solution:
Input work = (100/80)*500000 J = 62500 J
A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
for ex: A vector quantity has magnitude and direction.

We will solve this problem using the direct concept related to band gap energy, that is, a band gap is the distance between the valence band of electrons and the conduction band, i. e, the energy range in a solid where no electron states (Electronic state) can exist Mathematically can be described as,
Where,
h = Planck's constant
n = Energy level
mc = Effective mass of the point charge
R = Size of the particle
As you can see the energy is inversely proportional to the size of the particle:
Therefore if the size is decreased, the amount of energy is increased.
