In several activities you saw that light was scattered, transmitted, absorbed, or some combination of these. In the activity with the clear and colored water, you saw that the more light that was absorbed, the less that was scattered and transmitted. Is this relationship true for the object your teacher just showed you? Make a general rule about the way the amounts of light reflected or scattered, transmitted, and absorbed by any object are related to each other.

The answer is  a.first and third quarters 

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

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.
