I would say the correct option would be A. the amount she will earn for 35 hours of babysitting
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:
Portugal ⇒ Ruled east of the line of demarcation
After the New World was rediscovered by the European powers and saw competition between the Spanish and the Portuguese, Pope Alexander VI came up with a Line of Demarcation to divide the New World. Portugal was to rule over every land east of the line which is why they colonized Brazil.
Russia ⇒ Controlled what is Alaska today.
Russia controlled what is Alaska today but then decided to sell it to the United States rather than risking the British taking it by forced and adding it to Canada.
Britain ⇒ Controlled the area of today's eastern United States.
Britain ruled the eastern part of today's United States and it was here that they established the colonies that became the first states of the United States of America when these colonies defeated the British in the American Revolution.
Spain ⇒ Ruled west of the land of demarcation
As explained above, Pope Alexander VI came up with a Line of Demarcation. This allowed Spain to rule lands west of this line such that they gained colonies such as Mexico and countries to the west of South America.
Answer:1111 Km.
The circumference of the earth is about 40,000 kilometers and the earth has a total of 360 degrees.
If you want to know what 10 degrees is equal to, use a simple proportional equation.
10 X
------ = -------
360 40,000 km
Then, solve for X.... (cross multiply)
(10*40,000)/360= 1111.1111111
