Which statements are true?
a. science is a collection of facts that does not evolve. we have gained all the knowledge we can from science.
b. scientists observe natural events occurring around them. they question these observations and investigate them.
c. all scientists follow one scientific method of investigation.
d. if a hypothesis is not verified by the results from the scientific method, scientists may either redo the process or create a new hypothesis.
e. once they reach a conclusion, scientists often keep the results to themselves.

100 pounds is 100 pounds no matter the object or item being weighed

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
