Select the following that are true of cell walls in plants. 1. They give support and shape to the overall plant.
2. They contain very small holes.
3. They give the plant a deep green color.
4. They take the energy from the sun and turn it into carbon dioxide.
5. They measure the amount of water in a plant.

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
