Engineer It Preventing charge from building up on objects is necessary on some job sites. The buildup of charge may be a safety hazard or could damage products. A company wants to design a device to minimize the buildup of charge on an object. Which of the following materials would be the best choice to make such a device out of? A. aluminum, which transfers charge quickly
B. rubber, which barely transfers charge
C. a new plastic, which transfers charge at a moderate rate

Iam looking for this answer too!

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
