One end of a glass rod is kept in boiling water and the other end in ice water until temperature equilibrium is reached. then the two ends are switched, so that the hot end is in ice water and the cold end in boiling water. how does the temperature of the rod change with time? is the temperature harmonic?

mistakes are ok

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

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 .
