Lunar nodes

The Moon’s orbit around the Earth is tilted with relation to the Earth’s orbital plane by 5 degrees with two intersecting points – ‘Ascending Node’ and ‘Descending Node.’
Thus, despite the Moon being between the Earth and Sun on every new Moon, the three do not always come on a straight line or cause an eclipse. 
These nodes also rotate around the Earth once in 18 years.
In this way, if a new Moon takes place when a node is also between the Earth and Sun, the three come in a straight line and an eclipse takes place.

Demand and supply(I)/ Micro economics

  The quantity of a commodity that a consumer is willing to buy and is able to afford, given prices of goods and consumer’s tastes and preferences is called demand for the commodity. The relation between the consumer’s optimal choice of the quantity of a good and its price is very important and this relation is called the demand function. Consider any two variables x and y. A function y = f (x) As the value of y depends on the value of x, y is called the dependent variable and x is called the independent variable. The graphical representation of the demand function is called the demand curve. The relation between the consumer’s demand for a good and the price of the good is likely to be negative in general. In other words, the amount of a good that a consumer would optimally choose is likely to increase when the price of the good falls and it is likely to decrease with a rise in the price of the good. The negative slope of the demand curve can also be explained in terms of the two ...
