working with functions

The minimum amount of energy required to emit electrons from a metal surface is called the work function or threshold energy of that metal. The number of electrons emitted per second i.e. the rate of emission depends upon the material of the surface temperature of the surfa..

(1) Let the given function be f (x) on the real number line R. (2) Differentiate the function f(x) with respect to x and equate it to zero i.e., put f '(x) = 0. Solve for x. These values of x which satisfy f '(x) = 0 are called Critical values of the function (3) Arra..

Proteins perform essential and specialized functions in living cells. Proteins are primarily responsible for the structure and strength of the body. Some proteins act as enzymes, hormones, blood clotting factors, etc. These are the dynamic functions of proteins. Proteins perform..

Teachers organized a play for the annual day function in a school. Ms.Zelma takes 6 hours to dress up the children participating in the play. Ms.Alice takes 9 hours time to do the same job. How long would it take for both of them to dress all the children, if they worked togethe..

According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we user a low i..
