Fossil fuels such as natural gas and petroleum contain carbon. How did the carbon get into the fossil fuels? It was in the air that was trapped underground when the fossil fuels formed.

It migrated into them from the rocks in which the fossil fuels are found.

It was once part of the organisms from which the fossil fuels formed.

It seeped out of coal buried near the fossil fuel deposits underground.

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

Iwould think it is temperature, silica, oxides (gases)

The law of conservation of momentum will be the same no matter where you apply it.the equation will be  77.4 + m (mass of canister) *3.6
