Final answer:
The result of applying 'cons' with two atoms 'a and 'b is a list consisting of 'a as the first element and 'b as the second element.
Step-by-step explanation:
When 'cons' is applied with two atoms, say 'a and 'b, the result is a list consisting of 'a as the first element and 'b as the second element. This is because 'cons' is a function in programming languages that is used to construct a list by adding an element to the beginning of an existing list. In this case, the element 'a is added to the list containing only the element 'b.
