RCs: 51 to 60 Questions for CAT with Answers PDF

Passage

It’s always a welcome thing to learn that ideas that are commonplace in science fiction have a basis in science fact. One such fictional concept, “the warp drive” – alternately known as FTL (Faster-Than-Light) travel, Hyperspace, Lightspeed, etc. – actually has one foot in the world of real science. In physics, it is what is known as the Alcubierre Warp Drive. On paper, it is a highly speculative, but possibly valid solution of the Einstein field equations, specifically how space, time and energy interact.
Since Einstein first proposed the Special Theory of Relativity in 1905, scientists have been operating under the restrictions imposed by a relativistic universe. One of these restrictions is the belief that the speed of light is unbreakable and hence, that there will never be such a thing as FTL space travel or exploration. But then, in 1994, a Mexican physicist by the name of Miguel Alcubierre came along with proposed method for stretching the fabric of space-time in way which would, in theory, allow FTL travel to take pace.
To put it simply, this method of space travel involves stretching the fabric of space-time in a wave which would (in theory) cause the space ahead of an object to contract while the space behind it would expand. An object inside this wave (i.e. a spaceship) would then be able to ride this region, known as a “warp bubble” of flat space. This is what is known as the “Alcubierre Metric”. Interpreted in the context of General Relativity, the metric allows a warp bubble to appear in a previously flat region of spacetime and move away, effectively at speeds that exceed the speed of light. The interior of the bubble is the inertial reference frame for any object inhabiting it.
The mathematical formulation of the Alcubierre metric is consistent with the conventional claims of the laws of relativity and conventional relativistic effects. Since the ship is not moving within this bubble, but is being carried along as the region itself moves, the laws of relativity would not be violated in the conventional sense.
One of the reasons for this is because this method would not rely on moving faster than light in the local sense, since a light beam within this bubble would still always move faster than the ship. It is only “faster than light” in the sense that the ship could reach its destination faster than a beam of light that was traveling outside the warp bubble.
However, there are few problems with this theory. For one, there are no known methods to create such a warp bubble in a region of space that would not already contain one. Second, assuming there was a way to create such a bubble, there is not yet any known way of leaving once inside it. As a result, the Alcubierre drive (or metric) remains in the category of theory at this time.
In 2012, NASA’s Advanced Propulsion Physics Laboratory (aka.Eagleworks) announced that they had begun conducting experiments to see if a “warp drive” was in fact possible. This included developing an interferometer to detect the spatial distortions produced by the expanding and contracting space-time of the Alcubierre metric.
The team lead – Dr. Harold Sonny White – described their work in a NASA paper titled Warp Field Mechanics 101. He also explained their work in NASA’s 2012 Roundup publication: “We’ve initiated an interferometer test bed in this lab, where we’re going to go through and try and generate a microscopic instance of a little warp bubble. And although this is just a microscopic instance of the phenomena, we’re perturbing space time, one part in 10 million, a very tiny amount… The math would allow you to go to Alpha Centauri in two weeks as measured by clocks here on Earth. So somebody’s clock onboard the spacecraft has the same rate of time as somebody in mission control here in Houston might have. There are no tidal forces, no undue issues, and the proper acceleration is zero. When you turn the field on, everybody doesn’t go slamming against the bulkhead, (which) would be a very short and sad trip.”In 2013,Dr. White and members of Eagleworks published their results, which were deemed to be inconclusive.
When it comes to the future of space exploration, some questions like “how long will it take us to get the nearest star?” seem rather troubling when we don’t make allowances for some kind of hypervelocity or faster-than-light transit method. How can we expect to become an interstellar species when all available methods will either take centuries (or longer), or will involve sending a nanocraft instead?
At present, such a thing just doesn’t seem to be entirely within the realm of possibility. And attempts to prove otherwise remain inconclusive. But as history has taught us, what is considered to be impossible changes over time. Until then, we’ll just have to be patient and wait on future research.

FAQs on RCs: 51 to 60 Questions for CAT with Answers PDF

1. What are the benefits of practicing RCs for the CAT exam?
Ans. Practicing RCs for the CAT exam has several benefits. It helps improve reading speed and comprehension, enhances vocabulary and language skills, and develops critical thinking and analytical abilities. Additionally, practicing RCs helps familiarize candidates with the exam format and question types, allowing them to strategize and manage time effectively during the actual exam.
2. How can I improve my performance in RCs for the CAT exam?
Ans. To improve performance in RCs for the CAT exam, candidates should focus on developing their reading skills and comprehension abilities. Regular reading of newspapers, magazines, and books can help improve vocabulary, understanding of diverse topics, and overall reading speed. Additionally, practicing a variety of RC passages and analyzing the solutions can provide valuable insights into different question types and effective strategies for tackling them.
3. How should I approach difficult RC passages in the CAT exam?
Ans. When encountering difficult RC passages in the CAT exam, it is important to remain calm and focused. Candidates should start by quickly skimming through the passage to gain a general understanding of the topic and main ideas. They can then proceed to read the questions carefully, identifying keywords and any specific instructions. Breaking down complex sentences and paraphrasing information can help in comprehending the passage better. It is advisable to attempt easier questions first and then tackle the more challenging ones.
4. What are some common mistakes to avoid while attempting RCs in the CAT exam?
Ans. While attempting RCs in the CAT exam, candidates should avoid some common mistakes. One such mistake is spending too much time reading the passage without a clear strategy, leading to time mismanagement. Another mistake is relying solely on memory while answering questions, instead of referring back to the passage for accurate information. Additionally, poor understanding of the question or misinterpretation of the options can result in incorrect answers. It is crucial to read the questions carefully and analyze all the options before selecting the correct answer.
5. How can I improve my time management while attempting RCs in the CAT exam?
Ans. Effective time management is essential while attempting RCs in the CAT exam. Candidates can improve their time management skills by practicing timed mock tests and setting specific time limits for each passage and set of questions. It is advisable to allocate more time for difficult passages and questions while quickly answering the easier ones. Prioritizing accuracy over speed is crucial to avoid making careless mistakes. Regular practice and familiarity with different question types can also help in improving speed and efficiency during the exam.
