The diagram below shows a container filled with water. The three holes in the side of the container are sealed with rubber stoppers. The water exerts a pressure of 3000 Pa on the bottom of the container. The cross-sectional area of the bottom of the container is 0.009 m². a) What is the pressure exerted by the water on the middle rubber stopper, if we assume it is exactly half way down the column of water. Give your answer as a number, units are not required.

b) Describe the energy transfer that takes place when the rubber stopper at the bottom of the container is removed.

so easy. just google the electromagnetic waves and it’ll pop up.

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 .
