The prefix poly means many. So the word polynomial refers to one or more than one term in an expression. The relationship between these terms may be sums or differences. You call expression with a single term a monomial, an expression with two terms is a binomial, and expression with three terms is a trinomial. Here we are only discussing Binomial along with their exponents.
Let be an additional periodic force apart from the restoring force and the damping force,
then Amplitude in forced oscillation given by
Where is called a natural angular frequency.
and is the angular frequency of the driving force.
It is called the "zeroth" law because it came to light after the first and second laws of thermodynamics had already been established and named, but was considered more fundamental and thus was given a lower number , i.e zero.
The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object's mass and volume is called density, And density is an intensive property. But both object's mass and volume are extensive properties.
Electricity is a general word used to explain phenomena caused due to charge under rest or motion. In electrostatic we study about charge under rest and in current electricity we study about the flow of electric charge through a region.
Wien's displacement law is useful for determining the temperatures of hot radiant objects such as stars, and it is also useful for a determination of the temperature of any radiant object whose temperature is far above that of its surroundings.
