Answer:
The geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system)
Explanation:
<u>Hydrogen is used as fuel in automotives . It yields very high energy on combustion. It has great energy density by weight but poor energy density by volume. This is because Hydrogen is a very light gas, approx. 11 times lighter than normal air.</u> Hence it would require large volume of container to store it at normal atmospheric pressure conditions. That is why it is compressed using external energy to increase its density and decrease the volume needed for storage . So it becomes portable.
Only problem in this approach is that it utilities about 20% energy of the Hydrogen's energy potential to compress it . But this method proves cost effective as it reduces the overall weight of the container and also gives space to vehicles .

Answer:
157 miles per hour.
Explanation:
The saffir Simpson Hurricane Wind scale is the ratings 1 to 5 that is given to the hurricane on the basis of it's wind speed.
Category 5 hurricanes are the most dangerous hurricanes.Having the wind speed of more than 157 miles per hour.It can cause catastrophic damage such as destruction of houses,fallen trees,fallen power poles.After category 5 hurricane power outrage can last form weeks to months and the area will become uninhabitable for weeks to months.
