Develop a function called simulate that accepts two arguments, a list of job types and number of arrival times to generate. The function should generate arrival times for randomly selected job types. Each job arrives in a randomly generated time after the previous job. Generation always starts at time 0.

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.
