Comprehension

Answer the following questions.

a. What is a hyperloop? How does it work?

Hyperloop is a planned train that would be capable of travelling at incredible speeds. It’s superfast because it’s enclosed in a tube with no air in it. As a result of the lack of air, there will be no friction to slow the train down.

b. How is hyperloop more beneficial than the traditional trains?

Hyperloop is much beneficial and superior than any traditional or a high-speed rail. It’s less expensive and uses less energy since the track doesn’t have to provide electricity to the pods constantly and because the pods may depart every 30 seconds, it’s more like a demand-based service.

c. Does hyperloop have a successful history? How?

No, it does not have a successful history since the original concept for hyperloop was to use waggons and pneumatic tubes to transport mail and parcels between buildings.

d. Write the contributions of Robert Goddard and Elon Musk for the development of hyperloop.

In order to provide ultra-fast intercity transport, Space X and Tesla founder Elon Musk created the hyperloop idea. In addition to automobiles, aircraft, boats, and trains, Elon envisions a “fifth mode” of transportation that utilises travel pods housed within steel tubes. He revived interest in the idea of hyperloop in August 2013 with his ‘Hyperloop Alpha’ paper.

The ‘vactrain’ idea, created by Robert Goddard in the early 20th century, is clearly a prototype of the hyperloop. Since then, a slew of similar concepts have been proposed.

e. What relation does speed have with air resistance? Explain.

More Air resistance decreases the speed of a moving body and vice versa. Since, Hyperloop will travel through the vacuum tubes, the speed will drastically increase as the result of no-air resistance.

f. What are hyperloop capsules compared with? How are they similar?

Because both Hyperloop and Boeing 747 accelerate at the same measure of acceleration, Hyperloop capsules are likened to Boeing 747.

g. How do the passengers feel while travelling via hyperloop? What will be done to make it luxurious?

On a hyperloop, the passengers feel approximately the same as riding a lift or a passenger aircraft. The cabin shows beautiful scenery and each passenger has access to his or her own private amusement systems, to let them have a easeful travel.

h. Why does the writer doubt about the success of hyperloop? What does the success depend on?

Hyperloop’s success will be determined on the destinations, the local economy, and the geographical location. The author has concerns regarding hyperloop’s viability because of the enormous multibillion-dollar expenditure and the fact that the projects are still in the pilot and experimental phases. In the past, Nikola Tesla and Elon Musk had already closed the same concept program, due to no response from government authorities.

Within the state of Arizona, Rob, along with his family, moves frequently, from city to city. After his arrival, one of his first tasks is to find an apartment close to work as he does not have a car. Usually, there are many different places to choose from, and he considers cost, location, and luxury. If one apartment has a washing machine and dryer and cost four hundred dollars a month, he prefers to rent it over another apartment which has significantly less rent located two blocks from a Laundromat. Rob's family never want to live in an apartment on the thirteenth floor since all of them fear heights. He also tries to choose an apartment with landlords recommended by former tenants. Everybody know that it is important to find a responsible landlord. Rob and his wife love to cook together when both are free, so he needs a spacious, well-equipped kitchen. Rob often also looks for a place with an air conditioner because there are so many scorching days and nights in Arizona. Whenever Rob finds a new apartment, all of his concerns disappear. He feels relieved and call his mother. Someone understands!
