Consider a rigid body with moment of inertia i, which is constrained to rotate in the xy plane, and whose motion is given by the schrödinger equation, a) find the eigenfunctions and eigenvalues. b) assume the rotator has a fixed dipole moment p in the plane. an electric field e is applied to the plane. find the changes in energy levels to first and second order in the field.

The center is basically the heart of it

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
