Which of the following products is NOT derived from hydrocarbons?

Crude oil

Explanation: Crude oil is a liquid consisting of hydrocarbons found beneath the Earth's surface. Its refining yields several refined and more useful forms like petrol, diesel, kerosene, etc. All of them are hydrocarbons with different molecular weights. Hydrogen is the odd one out as it is an element and not among the end products of refining.

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
