Which of the following statements is incorrect?

a) it is not possible to know the exact location of an electron and its exact energy simultaneously.
b) the energies of an atom's electrons are quantized.
c) quantum numbers define the energy states and the orbitals available to an electron.
d) the behavior of an atom's electrons can be described by circular orbits around a nucleus.
e) electrons have both wave and particle properties.

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

Iwould have to say sorry i can't elaborate more. hope this though!
