Explanation:
Hydrogen is used as a fuel because it has a high calorific value per molecule when burned in air and also burns explosively. When burned in air, it reacts with oxygen to produce water which is safe for the environment. This same property of hydrogen of high explosiveness makes it difficult to store safely.
Hydrogen can be produced through the electrolysis of water. However this is high energy consuming. The most common method is called steam-methane reforming. Methane from hydrocarbon is mixed with steam under high pressure and reacts to produce hydrogen and carbon monoxide.
Diesel and petrol and other petroleum products when burned produce carbon dioxide which is a greenhouse gas. Greenhouse gases when increasing in the atmosphere, cause greenhouse effect that results in global warming.

Answer:
very low air pressure and that's not 100 points
Answer:
L
Explanation:
For every action, there is an equal and opposite reaction.
As the moment of inertia if the gyroscope is 1/10 of that of the remainder of the satellite, the angular velocity of the satellite will be 1/10 that of the spun up gyroscope and in the opposite direction.
L = Iω
