What does it mean when work is positive? velocity is greater than kinetic energy kentic energy is greater than velocity the environment did work on an object an object did work on the environment

Option (c) is the correct answer.

Explanation:

It is known that work is equal to negative of pressure times delta V.

Mathematically,      W = -

                                    = -

where                  P = pressure

  = change in volume

So, when work is positive then it means is negative.

                           W = -

                               = -

                               = +ve

Thus, we can conclude that when work is positive then work is done on the system or object by the environment.

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 .
