Comprehension
Answer the following questions
a.
What
is a hyperloop? How does it work?
→A hyperloop is an
ultra high speed ground transportation system for passenger and cargo. It works
easily and quickly in low pressure tubes, either above or below ground
b. How is hyperloop more beneficial than
the traditional trains?
→Hyperloop a more beneficial than the traditional trains because
it is quicker, economical and cheaper than traditional trains.
c. Does hyperloop have a successful
history? How?
→No, it doesn't have a successful history as the idea of
developing hyperloop was limited to the wagon and pneumatic tubes to send mail
and packages between buildings.
d. Write the contributions of Robert
Goddard and Elon Musk for the development of hyperloop.
→Robert
Goddard has proposed the concept of 'vactrain’ which was One clear predecessor
of the hyperloop. Elon Musk, an entrepreneur
who has
proposed the concept of Hyperloop Alpha paper
in August 2013, which set out how a modern system would work and how much it
would cost.
e. What relation does speed have with air
resistance? Explain.
→Speed
has very close relation with air resistance. If there is air pressure, the
speed may not be high. For example, airliners climb to high altitudes to travel
through less dense air; in order to create a similar effect at ground level,
hyperloop encloses the capsules in a reduced-pressure tube, effectively
allowing the trains to travel at airplane speeds while still on the ground
f. What are hyperloop capsules compared
with? How are they similar?
→Hyperloop capsules compared with air hockey game. They are
similar
to the way that the puck floats just above the table on an air hockey game.
g. How do the passengers feel while
travelling via hyperloop? What will be done to make it luxurious?
→ The passengers feel about the same as riding in an
elevator or a passenger plane while travelling via hyperloop. To make it
luxurious, beautiful landscape will be displayed in the cabin.
h. Why does the writer doubt about the
success of hyperloop? What does the success depend on?
→The writer doubts about the success of hyperloop because
of the investment i.e. a huge multibillion dollar. The
success of hyperloop depends on the destinations, local economics, and
geography.
Critical thinking
a.
Is
the hyperloop the future of transportation or just a dream? What do you think?
Justify your opinion with. suitable reasons.
→Hyperloop
is not a dream. It is the future of transportation. If some people think it as
a dream, I suggest them as positive dreams
are the main source and roadmap for future invention and development. The concept
of 'vactrain' has been developed by Robert Goddard early in the twentieth
century which is the clear predecessor of the hyperloop and Elon Musk who has really
reignited interest in the concept with his 'Hyperloop Alpha' paper in August
2013, which set out how a modern system would work and how much it would cost. Now
a days, people are quite busy. They want to do and go to their offices or
service field very quickly like the click of computer. Scientists and inventors
are also interested to invent the machine or devices which can be faster than
the previous. Bullet trains are faster than ordinary trains but the people as
well as scientists are not satisfied with the speed of it. They are thinking
about the invention of the means of transportation which can be faster than
bullet trains. Air transportation is also risky. So, in my opinion hyperloop is
the future of transportation.
It is said that the project of hyperloop needs a large
amount of investment. Investment is not the matter for developed countries.
They can easily invest huge amount of money to fulfil the desire and for the
betterment of the citizens. Because of these reasons, hyperloop can be the
future of transportation.
b. The number of private vehicles is
increasing day by day in Nepal beyond the capacity of our infrastructure. What
do you think should be done to curb the ever-growing number of private
vehicles? Discuss.
→The number of private vehicles is increasing day by day
in Nepal beyond the capacity of our infrastructure. The capacity of the road is
limited. Nepali citizens are more fashionable too. Most of the young people are
in developed western countries so those families whose member is in overseas
have high purchasing power. They buy personal vehicles in Nepal. In the recent
years, more and more people are able to afford the personal vehicles. There are
many advantages of having personal vehicles. They help to save time and to keep
privacy. But at the same time, they create negative and bad effects too. They
increase environment pollution, traffic jams and road accidents. There are
other problems too. The infrastructure of roads is insufficient to bear the
capacity of increasing numbers of vehicles. The government and the concerned
authorities should pay attention to this issue.
The following activities should be done to curb the rapid
growing number of private vehicles:
Firstly, people should be encouraged to use public means
of transportation such as buses, trains etc. Secondly, the existing roads
should be expanded on both sides. Wide roads help to reduce the intense
pressure of the vehicles. Thirdly, the governmental offices of transportation and
concerned authorities should restrict the use of old personal vehicles. Lastly, importing private vehicles should be
discouraged. This may decrease the number of private vehicles.
To discourage using private vehicles and to promote the
use of public transportation, the government has to take action and initiation.
At the beginning stage it is quite challenging to prevent people for using and purchasing
personal vehicles. If good awareness campaign is conducted, people may stop
purchasing private vehicles. For this, all should be loyal. The government and
citizens should act collaboratively. Citizen’s support is necessary for
government and government’s support is necessary for citizens.

B. Suppose you are the General Manager of Nepal Airlines.
Issue a press release on behalf of the airlines about the cancellation of
flights to the mountain regions due to the poor weather condition.
→
