CULTURAL QA01-2022-24 BEING A COMPILATION THERE MAY BE ERRORS
Q1 Do dogs ever go to a hiding spot todie, or is this something only wild animals do? A1 Lissa Bryan FormerAuthor at The Writer's Coffee Shop (2012–2017)Wed In the last few days of her life,my dog stopped eating. I even made her a steak to try to coax her, but sherefused. I let her out into the yard and she made herself a bed under a largebush. She didn’t want to come back into the house. I pleaded with her andtugged on her collar, but she wouldn’t budge. My husband finally picked her up and we put her on the carto take her to the vet. We knew we wouldn’t be bringing her home. She wastelling us it was time. Q2 How dangerous is a 10,000 voltelectric current? A2 Phillip Remaker Knowswhich end of a soldering iron to hold Updated Jan 15 It’s not the volts that kills you, it’s the amps. Volts are not current. A Van de Graaff generator found in a school science lab can produce10,000 volts easily, even 100,000 volts, and they are safe to touch. Thoughyour hair will stand on its end, and you could get an uncomfortable staticelectricity shock. On the other hand, 100V can kill you in just a few seconds, with enoughcurrent. My note- A high voltage and ahigh current – both are equally dangerous. High current is more dangerous. Consider thefact that current more than 10mA can kill you ! Whereas even if you experiencehundreds of volts, you won't beaffected at all provided the current through you remains below 5mA. Both can bedangerous, but High Voltage and current upto 20mA isextremely dangerous. Q3 Are all mother-in-laws difficult? A3 Gopalkrishna VishwanathMarried just once 43 years ago and still married to the same woman. Thu For whom? For the husband? Or the wife? Usually, husbands in India have no problem with their mothers-in-law forthe simple reason that they don't live under the same roof. But it is common for wives in India to find their mothers-in-law“difficult”. Or else it could be the mother-in-law finding thedaughter-in-law “difficult”. They are competitors for the affectionof the poor man caught in between, the man who is a son to one and a hubby tothe other. They say no kitchen is large enough for two women. I would expand that to“No house is large enough for two women”. In most families, mothers-in-law areusually not difficult if they don’t live together. I have often been asked if Ihad any problem due to my mother and my wife not getting along. I am retrieving that old answerand quoting it here. Whether your wife and mom get along with each other or not, depends on their personalities,their respective levels of education, whether it was a love marriage or anarranged marriage, the differences in economic status in the two families,whether they are both homemakers or if one of them is employed, or both areemployed, whether the health of the mother requires assistance and support fromthe DIL. There may be other factors too that come into play. Sometimes they get along famously, sometimes theirwavelengths do not match. There is no uniform strategy that a husband can adopt that is valid forall families. It is common for a husband to be tornbetween his love for both the mother and his wife. When the fault isclearly identifiable as that of the mother, or that of the wife, the husbandmust firmly stand by the person who is right and bring around the defaulter by facingthe situation squarely. He should not shrug off the problem with the thought“These women are incorrigible. Let them sort it out. I am not getting involved”which is a common escape route adopted by many Indian hubbies. Actually, the safest way tomaintain a cordial relationship is to live separately after marriage. If the parents are old and need the support of thenext generation it would be better if the couple lives close to their parent'shouse or if the parents move to a house or apartment in the same place wheretheir son or daughter lives but maintain a separate establishment as far aspossible and affordable. I have always believed a manshould not marry if he can’t afford to live on his own in a separate house. If he holes up with his parents, he and his wife must bewilling to put up with the Mother. It’s her house. She’s the boss. Thedaughter-in-law has no choice. All she can and must do is to coax her husbandto move out as early as possible. This is particularly important if the husbandhas brothers and sisters living in the same house. If after knowing thesituation, the wife has agreed to marry into such a family, she has no choicebut to rough it out if she is unable to get along with her MIL. If the situation is reversed, themother must realize that thetime has come to pass on the baton, and she must be content to withdraw from active householdmanagement and offer quiet support. Doting on the grandchildren isone great way to get into the good books of her son and daughter-in-law. Bottom line: The problem does not admit a standard solution. It is better avoided than solved.I know some girls who were so paranoid that they asked their parents who werelooking out for grooms to look for a boy whose mother was no longer alive. I am reminded also of parents struggling to find matches for theirmediocre sons, going out of their way to reassure the families of prospectivebrides that the Mother of the boy was a “Pious Lady”. (Read TOI columnistSantosh Desai’s hilarious essay in his book “Mother Pious Lady”) Q4 When did household clocks becomecommonplace, and what technology made that possible? A4 Boris Zakharin SoftwareEngineer (2004–present)Wed The first reported house clocksare from 1314. This isabout the time when fully mechanical clocks were invented. The bigtechnological breakthrough that made them possible is the verge escapement. By AlienAtSystem - Own work, CC BY-SA 4.0, File:VergeEscapementCycle.gif- Wikimedia Commons This device allows clock gearsto tick at regular intervals. Its inventor is unknown, but this invention is considered to be themost important invention in the history of mechanical clocks, maybe even allclocks. The verge escapement was used in clocks and watches through themid-19th century (500 years!) until a more modern escapement (the leverescapement) became cheap enough to replace it in wristwatches (larger clocksreplaced it with a pendulum a century earlier). Q5 Where is the "glassbridge" found in India? A5 Sushang Agnihotri..Jan15 Indians should be proud of their country that after China, magnificent glass bridges havestarted being built in India too. Glass Bridge, also known as SkyBridge, Glass Bridge and Sky Glass Bridge. Let's start with the country's first sky bridge:Firstsky bridge built in Pelling, Sikkim first sky bridge. Here the country's first sky bridge is built inPelling, Sikkim.Which is situated at an altitude of 2150 meters above sealevel. Check out its stunning pictures :Although it is not a completely sky glassbridge. Because there is something else instead of glass in between. Glass Sky Bridge of Nalanda, Bihar: But the country's second, but completely sky or glass bridge has been built in Nalanda,Bihar. This glass bridge is so spectacular that no one can see it.ts length is85 feet and width is 6 feet. Its height from the valley is about 250 feet. Considering the capacity of thebridge, the number of people visiting the Glass Skywalk daily has now beenincreased to 800. But only 15 to 17 people can go on itsimultaneously.Officials claim that this bridge has been built on the lines ofthe Sky Walk Bridge built in East Taihang of Hebei province of China.Thespecialty of the bridge is that from here you can fully see the nature safariof Rajgir.The construction of this glass floor bridge has been made likethe glass floor bridge of China, but the construction agency is fromMaharashtra.It iscrafted with 3 strong layers of glass. Rs 1.47 crore has been spent on itsconstruction. At the same time, the third glassfloor bridge of the country is to be built in Rishikesh, Uttarakhand. My note- Glass bridgeinformation is new to me. Q6 Does an RO water filter reduce thehardness of water? A6 Dev Mehta, Alwaysbattling the beast – Water Answered Nov 16, 2019 YesYes Hardness is the count of calcium carbonate in your water. Calciumcarbonate like any other mineral is removed from the water during the reverseosmosis RO process. This happens due to the 0.0001micron semi permeable membrane in an RO system. The membrane does not allow any minerals to passthrough. Thus, as a part of the process the water is demineralised and becomescorrosive in nature (hungry for minerals) An RO also wastesup to 70% of water each time you run it. For instance 1 glass of pure water from an RO costs 2 glasses of wastedwater. Now at an average consumption of 5 litres a day for a 4 person household the yearly consumption would be 4*5*365=7300Litres of water. Now, if thiswater was procured from an RO we're wasting around twice that amount - about14,600 litres in a year! So yes an RO will reduce the hardness of your water but due todemineralised output excess water wastage it is definitely not the mostefficient or sustainable way to get rid of hard water problems. Try a water conditioner instead! Q7 Why can't a helicopter fly above25,000 ft maximum? If the reason is the air above that level gets thin, thenhow come jet and other commercial airplanes fly above that levels? A7 Subhadeep Paul MilitaryAviation buff Updated Jan 12 Finally a very good question. Understand how a helicopter flies in three simple steps: Its rotors, which are basically airfoils, rotate to produce a relativemotion with respect to the air around it. This motion causes air to flow over the rotors like they do in wings ofa fixed wing aircraft (& hence helicopters are called rotary wingaircraft). This flow ofair over the rotor generate lift & hence the helicopter takes off. The lift generated by the rotors are directly proportional to the densityof air. So naturally asthe helicopter gains altitude, the air becomes thinner & its ability togenerate lift keeps decreasing until upto an altitude where therotors can just generate enough lift to counter the weight of the chopper. Thisis the service ceiling of the helicopter. At the service ceiling the maximumlift coefficient of the blades is reached. Also at the service ceiling, the helicopters cannot hover. They can fly & maneuver alittle but cannot hover. Maximum hovering altitude is determined byparameters like HIGE/HOGE - Hover in/out of ground effect. Different story foranother day. So, why do fixed wing aircraftfly higher than helicopters ? Simple reason being the way fixed wing aircraft generates the lift isdifferent. There is a engine which pushes (or pulls in case of a turboprop) theaircraft to great velocities. These speeds provide a great lifting capabilityfrom the wings which unlike a helicopter do not rotate or move from the enginepower. Now one can argue that in an helicopter, we can rotate the rotor bladesat high rpm from an immensely powerful engine to increase the lift coefficient.We can do that but to a limit. Beyond that limit when the speed is extremely high, the efficiency ofblades actually drop (I read this but couldn’t find a source). The world record for flying at highest altitude for a helicopter wasfirst created in 1972 by a French pilot in SA315B Lama (initial variant ofCheetah Helicopter). He took the light but powerful Lama to 40,800 feet wherethe engine flamed out & he had to land by autorotation. The current world record is heldby Eurocopter (now Airbus) AS350 (pic below) in 2002 when the helicopterreached an altitude of 42,500 feet. Fun Fact: Indian Air Force Cheetah helicopters (pic below) routinely flyabove 20,000 feet keeping the soldiers well supplied at the world’s highestbattlefield known as Siachen Glacier. Edit 1 as suggested by Vivek Tulja : I think the issue with applying morepower to achieve higher rotation speeds is that at some point the rotor (orpropeller) tips begin to reach sonic velocity, and at that point the airflowbecomes more turbulent which causes loss of lift. Also, additional stresses andvibrations in the transonic region mean that you need greater structurestrength which means higher weight requiring even more power. Q8 Why would a cat hiss at someone? A8 Jaimes Roe 25+ yearsof studying, researching, and pondering cats Thu Cats hiss when they are verystressed in some way. It’s a warning. Reasons cats hiss: Fear The main reason cats hissis because they’re afraid.Our older male cat used to always hiss at us if we wore boots. He was afraid ofmen, and I have no doubt he got kicked by someone wearing boots when he was astray. Territorial If a new person oranimal comes into theirterritory, or another cat is encroaching on their food, toys, or sleepingspots, they will hiss to warn them to go away before they attack. Pain If a cat hisses as they’removing or trying to getcomfortable, it’s a sign that the cat is in pain. Do not ignore this. ALWAYStake a cat to the vet if you observe this behavior. Angry If someone is pesteringor bothering the cat, the catwill hiss as a warning that they have reached their limit, and the next step isviolence. Play Some cats hiss when theyplay fight. This can be veryconfusing for humans who see a cat hiss at another cat and then launch intosome rough play. Dementia Sometimes cats withdementia will not recognizetheir people, and may hiss because they are confused about who you are. If yourelderly cat starts hissing at you, take them to the vet ASAP. Other stress Anything or anyonenew, including smelling or hearing acat or person they don’t know, can cause cats to hiss. Any upset in the homeenvironment can make them afraid or cranky. Some cats hiss more frequently thanothers. Try to evaluate the severity ofthe situation. Empathize with thecat. See things how they might see them, not as you see them. If their behaviormakes sense, just remember not to put them in that situation again. If youcan’t figure out what’s happening to make them hiss, take them to the vet. Q9 Why do majority of Indian peoplehave so much obsession with government jobs? Why don't they like to followtheir passion? A9 D D Rishi Former IRS |Advocate | LL.

A10 Tak Nomura StudiedAccounting, Economics and Philosophy in college. 41m Economics is social science. There is no tool to measure the future economicprogress of any economy, because it’s not 100% is controlled by humans. Thiswas proven from the covid pandemic that caused the world economic recession. Economics is a social science concerned with the production,distribution, and consumption of goods and services. It studies howindividuals, businesses, governments, and nations make choices about how toallocate resources. ... The building blocks of economics are the studies oflabor and trade.
