CULTURAL QA 04-2022-22 BEING A COMPILATION THERE MAY BE ERRORS
Q1 How does hot water turn into ice faster than cold water? A1 Ken Freeman , 45 YearsRadio Station Chief Engineer Answered Jul 27, 2019 Simply put, it doesn’t. Put a container of hot water and an identicalcontainer of cold water into a freezer right next to each other at the sametime and see which one freezes quicker. The ONLY possible way that the hot water could freezefaster at different times is if putting the hot water into the freezertriggered the freezer to turn on when it normally wouldn’t have turned on,thus lowering the temperature of the freezer lower than it would have otherwiseand if putting the same container with cold water would not have raised thetemperature in the freezer enough to turn on the compressor and lower thetemperature at all. Otherwisethis is an “old wives tale”. Q2 Does an extra coach get added to Rajdhani if there are morethan 72 waitlisted passengers under tatkal scheme? A2 Ankit Barnawal FormerStudent at Doon Business School, Dehradun (2017–2022)7h No, the extra coach does not get added to Rajdhani Express if there aremore than 72 waitlisted passengers under tatkal scheme. In place of Rajdhani Express, you can assume any other trains for this situation. The extra coaches in the trainare added during the specific time period like festival season with the priornotice issued by the railway zone on which the train operates. Many superfast and mail expresstrains gets an extra coach but there is very less chances that the Rajdhani Expresswill get an extra coach. Q3 People are assuming plants don't have enough aminoacids forthe daily recommendation. What about ruminants, a cow for example? It must getall the aminoacids from the grass, basically. Correct me if I'm wrong. A3 Ken Saladin Formerprofessor of histology (microscopic anatomy)Sun For one thing, theamino acid requirements for humans aren’t the same as the requirements for allother animals. Species differ in the presence or absence of theenzymes needed to convert one amino acids into another, and the differ in thecommunities of intestinal microbes that may make amino acids the hosts can use.You can’t assume thatthe ones that meet the needs of a ruminant meet the needs of a human. For another, ruminants eat a lot more meat that most people realize. Deer, cows, horses, goats,squirrels, chipmunks, rabbits, and other herbivores eat a lot of insects andother invertebrates, and sometimes eat rodents, rabbits,ground-nesting birds, and carrion. If offered to them, they’ll eat beef and fish. Q4 What does "pissed" mean in British slang? A4 Claire Jordan Degree inbiology and folklore; programmer, shop owner, secretary on newspaperApr 13 Very drunk. Or the past tense ofto piss, which means to urinate. But to be pissed off is to beangry or resentful. To “take the piss” is one of a set of mysterious British phrases whichmean you are teasing somebody by conning them into believing something untrueor silly - along with “taking the Micky” and “pulling their leg”. By extensionwe also hear “extracting the urine” and “extracting the Michael”, and thetraditional response to having understood that you are having your leg pulled,which is “Pull the other one: it’s got bells on”. This may have something to dowith Morris dancing, which traditionally involves tying a leather pad coveredwith little bells to your shins. “Taking the piss” can also meantaking unfair advantage of someone or something, or extracting more benefit from a situation than is strictly fair— also known as “swinging the lead” (pronounced LED as in the metal, not LEEDas in a dog-leash). Note that the US expression“pissy”, if used in the UK, would mean you had wet yourself. The UK equivalent would be “ratty” or “snappy” orjust “bad-tempered”. Q5 Can we set the AC temperature at 29 or 30 Celsius? Does itcause any problems? A5 Gopala Krishnan , formerAssistant General Manager 1996-2004 at Department of Telecom(1966-2004)Answered just now I have read all the answersbefore my answering. I have a2 ton LG AC unit installed in my hall with opening to staircase upstairs andconnected dining room. Hall is 20x15 feet. It’s setting is 30 degree and I get cool air in the halland less cool air in dining. If I set to 24 degree C coolingis much more. I haveto change it to 28–30 degrees. I have gone through the booklet before answering this QA, not to give aWRONG ANSWER. Normal setting is 30 degree given in the booklet 18–30 degrees one canset. More Technicaldetails are not given in the booklet. 2nd answer- VijayMahajan, 33 years serviced in MSPGCL as a Electrical Engineer Answered Jun 27, 2019 No problem, At 30℃ youmay feel some hot. 29℃ isquiet satisfactory to body. 3rd answer-VivekSingh , UG Physics & Mechanical Engineering, Indian Institute of Technology Jammu (2019)Answered Jun 26,2019 Assuming you do not have a AC with built-in heater, if this assumption iswrong then no problems. If not.. Still no problems butis limited by the surrounding temp. Case 1-if your surrounding temperature is more than 30c then its fine Case 2-if your surroundingtemperature is less than 28c you can’t achieve a higher temperature —impossible (‘nature’s rule’). The ac will remainin off state because of the sensor. Hack: you can do this by puttingyour ac outside and theradiator inside the room.(so it cools the outer surrounding (outside thedesired room.) And heats the desired room) Case 3-temperature of surroundingis already 29c, no needfor ac. Save electricity. This is because the ac absorbs heats ( as a result cooling) from thesurrounding (heat is used to evaporate the refrigerant.) To bring down thetemperature of the surrounding. While the radiator does the opposite, it rejects heats to the surroundingand making the refrigerant liquid again. This is beyond nature’s rule & hence we have to pay for theelectricity. 4TH ANSWER- Harindrakumar , former lecture inphysics in science college answered jun 27, 2019 If you run your ac at 30 degree then it will not run at all because whentemperature set is higher than the temperature at night. During day time youdon't bother for running ac but due to continuous on and off compressor mayfail. My note- Still I recollect anannouncement in the flight fromTrivandrum to New Delhi, when it landed in winter, the outside temperature is 8degrees, they has set to 18 in the flight. Q6 What would happen if the oxygen in Earth’s atmosphere was38% oxygen instead of 21%? How would life be different? A6 Steven Haddock LL.B.degree, 25 years in litigation, administrative law, collections, bankrupty andprofessional regulation Apr 16 In earth’s early history,oxygen levels were much higher. Plants were just pumping out the stuff like crazy and there were few animals that used it, soit just accumulated in the atmosphere. The result? Much larger land invertebrates. Land based invertebrates don’thave a circulatory system, so any tissue that needs oxygen has to be directlyexposed to the air. This limits their size. This is a Goliath Beetle. It’s about the size of an adult human hand. Itsexoskeleton has several folds to allow air to get further inside. If it wereany larger, Oxygen couldn’t reach vital tissues. But back in the days wheretrees rules and nothing could decompose them, land invertebrates grew much,much larger. Here’s a fossil of a giant millipede. Here’s a model of a giant dragonfly. Yes, we have fossils of those too. Even tiny changes in oxygen concentration allow invertebrates to growmuch much bigger. Inwater, it isn’t a problem. Water can get pretty much everywhere. Q7 What is an overview of Jewish conceptions of the afterlife? A7 Claire Jordan Degree inbiology and folklore; programmer, shop owner, secretary on newspaper Apr 10 There isn’t an organisedbelief, although some Jewish sects have believed in reincarnation, and somehaven’t really believed in an afterlife at all. But if you’re interested, there’s a book calledDoes the Soul Survive? by a Rabbi Elie Kaplan Spitz. It’s about his personaljourney towards belief in an afterlife, but iirc it also gives an overview ofpast Jewish thought on the subject. Q8 Why didn’t no one paid attention to Da Vinci’s planes andhelicopters designs, instead of having to wait 400 years for the Wrightbrothers to inspire in something similar? How advance would we be today ifaviation was invented 400 years ago? A8 Andrew McGregor PerformanceMeasurement Lead at Fastly (company) (2019–present)Wed Da Vinci’s designs have two reallyobvious problems. No engines, and no controls. Others solved the control problems before the Wright brothers came along(and solved them better too). Aviation had to wait until asuitable engine was possible. That was the Wright brothers’ contribution. Human-powered flight is only possible with advanced materials; you can’tdo it without carbon fiber and mylar. Q9 How many watts does a 1.5 HP air conditioner use? A9 Gopala Krishnan, formerAssistant General Manager 1996-2004 at Department of Telecom(1966-2004)Answered just now I hope you mean 1.5 ton AC, per hour. On that basis I am answering. It depends mainly on the location where it is used and the period AC isin use. In Chennai where night temperature is around 32 degree C, an AC unit of1.5 ton used in a room size of 12′x12′ from 10 PM to 6 AM for eight hoursconsumes between 12000 to 13000 watts. While using Air Conditioners make it a point to open atleast one window half open to permit fresh air inside and avoid suffocation onany problems. Q10 How many grinders should I have in my kitchen? A10 Gopala Krishnan, formerAssistant General Manager 1996-2004 at Department of Telecom(1966-2004)Answered just now With a lot of advance inelectric appliances in kitchen, it is desired to have minimum appliances within kitchen. Kitchenshould not be crowded with appliances. Best is to have a mixer grinder. Refrigerator has to be kept asfar as possible outside kitchen preferably in dining room. Wet grinder can be kept in work area since it is mostconvenient in work area. Coconutscrapper , mostly used once or twice a week can be in store room. Itis a practice among women to scrap 4–5 coconuts at a time and keep the flour ina container inside refrigerator. Any other grinder can be in store room.
