What is gangue particles???​

a mineral that is basically rendered useless  in the modern world. it is the mineral that surrounds a desired ore deposit. there is no known use for it.

Explanation:

                        The gangue particles are the unwanted materials or impurities like sulfide, oxides, silica sand etc which are mixed in minerals and which are removed during extraction of pure metals.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
