You have built a device that measures the temperature outside and displays it on a dial as a measure of how far away from room temperature outside is. the way the dial works is that a needle with a charged ball on the end is placed between two charged parallel plates. the strength of the uniform electric field between the plates is proportional to the outside temperature. given that the charged ball on the needle has a charge of?

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
