You crumple a piece of paper in your hands. Not all of the kinetic energy from your hands is used to crumple the paper. Where does the rest of the energy
go?
A. It is transformed into magnetic energy.
B. It is transformed into light energy,
C. It is transformed into electrical energy.
D. It is transformed into sound energy

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

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
