Entropy is the measure of the disorderliness in a system. Theoretically, the entropy can be zero. But, practically, the entropy cannot be zero... View Article
The flux of a vector field through a closed surface is always zero if there is no source of the vector field in the volume enclosed by the surface.... View Article
The Stefan Boltzmann law states that the amount of radiation emitted per unit time from an area A of a black body at absolute temperature T is... View Article
In DC, the current is constant at any given time. The time period of a DC supply is constant. We know that the relationship between frequency... View Article
The modulation factor in amplitude modulation is the ratio of change of amplitude in carrier wave after modulation to the amplitude of the... View Article
Most digital instruments display the measured values in discrete numerals, thereby eliminating the parallax error commonly associated with analog... View Article
Space vehicles apply action and reaction forces to blast off by using rockets to thrust down toward the ground. In reaction, the space vehicle is... View Article
An Adiabatic process is characterized by an increase in entropy if the process is irreversible and no change in entropy if they are reversible.... View Article
Destructive interference occurs when the maxima of the waves are 180 degrees out of phase. The amplitude of the resulting wave is zero. Read... View Article
