You have a 100-watt light bulb on your front porch that is turned on 10 hours every night. If the cost of electricity is 12 cents per KWHR (kilowatt hour), how much does that bulb add to your monthly electric bill? Give your answer in US dollars ($). Remember 100 cents = $1.

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
