Joseph Lister was an English surgeon who pioneered the idea of sterile surgery. He was inspired by the work of Louis Pasteur, a French chemist and microbiologist who helped to prove that many diseases are caused by bacterial cells infecting the human body. Lister applied this knowledge to the practice of surgery by developing many processes and procedures for keeping surgical tools and bodily wounds free of microscopic infectious agents.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
