Suppose that l is a list is of length n and it is sorted using insertion sort. if l is already sorted in the reverse order, show that the number of comparisons is (1/2)(n 2 – n) and the number of item assignments is (1/2)(n 2 +3n) – 2.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
