Which of the following is an example of conduction ? A A person warms their hands by the campfire . B A soup spoon gets hot after sitting in a bowl of hot soup . Warm air rises. D The sun warms the sand at the beach.

B A soup spoon gets hot after sitting in a bowl of hot soup .

Explanation:

Conduction is the movement of heat energy from one part of a material to other parts of the material . It is usually associated with solids .

If you sit a soup spoon in a bowl of hot soup, the hotness of the soup is transferred from the soup to the spoon. The part sitting in the soup becomes hot after sometime because of the heat energy transferred from the hot soup to the spoon .

This hotness is then transferred from the part of the spoon sitting in the soup to the handle of the spoon .

Conduction is said to have taken place because the hotness of the soup has now transferred from the soup to the part of the spoon in the soup and also to other part of the spoon

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 .
