Q1 Wheredoes the Earth’s internal heat come from? A1 Ananda Sankar Swain,The only truewisdom is in knowing you know nothing.” Dec 14 Earth generatesheat. The deeper you go, the higher the temperature. At 25km down, temperatures rise as high as 750°C;at the core, itis said to be 4,000°C. Humans have been making use of hot springsas far back as antiquity, andtoday we use geothermal technology to heat our apartments. Volcanic eruptions,geysers and earthquakes are all signs of the Earth’s internal powerhouse The process bywhich Earth makes heat is called radioactive decay. It involves thedisintegration of natural radioactive elements inside Earth – like uranium, forexample. Uranium is a special kind of element because when it decays, heat isproduced. It’s this heat that keeps Earth from cooling off completely. Q2 Whydo airplanes appear to fly much slower than they actually do? A2 SomaGarner, Fri Airplanes appear to fly much slower than they actually dobecause of the vast distances that they cover. When you look up atan airplane in the sky, it may seem like it is moving slowly, but in reality, airplanes can travelhundreds of miles per hour. This means that even though an airplane appearsto be moving slowly from your perspective on the ground, it is actuallycovering a great distance very quickly. Additionally, whenlooking at something far away our eyes tend to perceive movement as beingslower than what it really is due to optical illusions and other factors. My note- The speed and height are felt low even when one person travel in aplane. I recollect in aflight from Delhi to Chennai in 2004,the pilot covered 3/4thof the distance in one hour. Then the flight was moving very slowly making anillusion, whether any problem with the aircraft. However he landed 15 minutes before the scheduled arrival. Q3 Canwe eat apple and milk together?

Q4 Whydo airlines follow a hub and spoke model? For example, why do Emirates Airwaysflights go to Dubai first and then from there go to other destinations? A4 Bradley Baxter,Save 90% on flightswith Mighty Travels.13h The hub and spoke model is a popular airline businessstrategy that allows airlines to maximize their efficiency. By having one central hub, such as Dubai for EmiratesAirways, the airline can easily connect passengers from multiple destinationsto each other without having to make too many stops along the way. This helps reducecosts and increase profits by allowing them to fly more routes with feweraircrafts. Additionally, it also makes it easier for travellers whoare looking for connecting flights since they only have one stop instead of twoor three different ones. In short, thismodel helps airlines save money while providing customers with an efficienttravel experience! Q5 Wasthe Madurai Meenakshi Temple closed for 60 years during the Sultanate dynasty?Later which ruler destroyed the Sultanate forces and freed the temple? A5 Aazhwarkadiyan, Lived in Madurai,Tamil Nadu, India (1976–1999)Sat MaduraiMeenakshi temple was closed during the rule of the Madurai Sultanate(1335–1378). Not much is left in Madurai, except the mosque of Goripalayam,Kazimar Street and a tomb on top of the Tirupparankundram hill. It was a differenttime, when Islamic rulers were plundering Hindu temples. The guardians of Meenakshitemple thought it wise to wall the temple and close it, to protect the sanctumsanctorum of the shrine of Meenakshi and Sundareswarar (Shiva). Similar was thehistory at Srirangam temple. MaduraiSultanate - Wikipedia Kingdom based inthe city of Madurai in Tamil Nadu, India Sultanate of Ma'bar مابار سلطنت Capital Madurai Common languagesPersian (official) Religion Islam (official) Government Monarchy• 1335–1339 Jalaluddin Ahsan Khan • 1368–1378 Sikander Khan History• Established 1335 • Disestablished 1378 Today part of India Ma'barSultanate ( Persian : مابارسلطنت ), unofficially known as the MaduraiSultanate , was a short lived kingdom based in the city of Madurai in TamilNadu , India . The sultanate was proclaimed in 1335 led by Jalaluddin AhsanKhan declared his independence Delhi Sultanate of Madurai. Ahsan Khan and hisdescendants ruled Madurai and surrounding territories until 1378 when the lastsultan, Ala-ud-Din Sikandar Shah fell in battle against the forces of theVijayanagara Kingdom. Duringthis short span of 43 years, the Sultanate had 8 different rulers.Origins [ edit ] TheChola kings, who dominated Tamil Nadu for over two centuries (approximately 950AD to 1200 AD) waned, and Pandya kings had the upper hand for the next century(approximately 1200 AD to 1300 AD). King Maravarman Kulasekhara Pandyan (1268 -1310) had two sons Jatavarman Sundara Pandyan and Jatavarman Veera Pandyan. Theelder son, Sundara Pandyan, was by The king's wife and the younger, VeeraPandyan, was by a mistress. Contrary to tradition, the king proclaimed that theyounger son would succeed him.This enraged Sundara Pandyan. He killed thefather and became king in 1310. Some local chieftains in the kingdom sworeallegiance to the younger brother Veera Pandian and a civil war broke out. [1]Sundara Pandyan was defeated and he fled the country. He sought help from thefar off northern ruler Sultan Ala-ud-din Khilji , who was ruling much ofnorthern India from Delhi. At that time, his army under General Malik Kafur wasin the south at Dvarasamudra (far to the north of Tamil Nadu). Khilji agreed tohelp Sundara Pandyan and ordered Malik Kafur's army to march to Tamil Nadu. With Sundara Pandyan'sassistance, this Muslim army from the north entered Madurai in 1311.Many historians believe that Malik Kafur, who was based in Dvarasamudra at thattime, was not planning to march south all the way to Tamil Nadu, and that, butfor Sundara Pandyan's request to Sultan Ala-ud-din Khilji, he would never haveinvaded Tamil Nadu. Thus the first invasion of Tamil Nadu fromDelhi was a direct result of the internal quarrel in the Pandyan royal family.[2] Following this there were two more expeditions from the Delhi Sultanate –the second in 1314 CE led by Khusro Khan and the third in 1323 CE by Ulugh Khan. These invasions shattered the Pandyan empire beyond revival. While theprevious invasions were content with plunder, Ulugh Khan annexed the formerPandyan dominions to the Delhi Sultanate as the province of Ma'bar. Most ofSouth India came under the Delhi's rule and was divided into five provinces –Devagiri, Tiling, Kampili , Dorasamudra and Ma'bar. [3] In 1325, Ulugh Khan acc A false lingam waskept outside the walled shrine , to which the soldiers were trying to breakusing crowbars. The idol is still kept on the corridor ofMeenakshi Temple with its history written in a board in Tamil and English. Kumara Kampanna, a son of Bukka RayaI, one of the brothers who found the Vijayanagara Dynasty, led an army to thefar south , and defeatedthe last ruler of the Madurai Sultanate, ending the dynasty and the rule.Meenakshi temple was then reopened. His exploits are written by his wife Gangadevi in aSanskrit Book Madura Vijayam . My note- An excellent informative answer for persons likinghistory. Q6 Whatare the warning signs for prostate cancer ? A6 Divya Solanki, Ex Assistant ProfessorObstetrics and GynaecologyatESI & PGIMR Basaidarapur Delhi (2019–present)Dec 25 My father was ahealthy man .He was just 56 years old. He had constipationwith bleeding with his stools .I took him to a senior doctor when he startedhaving this problem. I felt he should be examined properly as one of my seniorhad lost her father to cancer rectum and had similar complaints.I got him checked by two senior surgeons of my hospital who said he justhad haemorrhoids (piles) and treated him for same . One day he had lower pain abdomen and burningmicturation. I got his urinetest done which was normal so i asked him to get an ultrasound done which showed his prostrate wasenlarged. So I took him to a urologist in my hospital whoasked papa to get a prostrate specific antigen which came out to be near 4000 (four thousand). The normal value ofProstate specific antigen (PSA) is just 0-4. So I called one ofmy very senior surgeon who told me it was advanced stage prostrate cancer. Than I took him tocancer hospital and than his treatment started . He was ahandsome healthy man who had just slight lower abdomen pain and burning whenhis cancer was diagnosed. I feel PSA(prostrate specific antigen) should be routinely done for all men who are above50 years of age and should get an ultrasound pelvis also done. If someone wouldhave got it done for my father ,he might have been alive .I had showed him toso many surgeons , it should have been picked in digital rectum examination. I feel soawful at times.Though he lived for 4 years after his diagnosis and he got thebest treatment one could get at stage 4 but I feel it is always better if wecan catch this deadly disease at initial stages. Getting a simple blood test such asProstrate specific antigen is a very good diagnostic marker. It should be inroutine testing for all males after 50 years of age . My note- A touching answer by adoctor about her father. If the case ofa doctor’s father is this, what aboutordinary persons? Mostconsider difficulty in passing stools isdue to lack of drinking water, not consuming enough fibre items, somemedications etc. Q7 Ihear a lot of doctors are telling their diabetic patients to stop takingmetformin. Why is that? A7 Diabetes Today Answered by JENNI 3h It is not accurate to say that doctors are generallytelling their diabetic patients to stop taking metformin. In fact, metformin is often the firstmedication that is prescribed to people with type 2 diabetes, as it has beenshown to be effective at lowering blood sugar levels and reducing the risk ofcomplications associated with the condition. There may be somespecific cases in which a doctor may recommend that a patient stop takingmetformin, but this would depend on the individual patient's specific circumstancesand needs. For example, a patient may need to stop taking metformin if they are experiencingside effects from the medication, if they are pregnant, or if they areundergoing certain medical procedures that may interact with the medication.However, in general, metformin is a safe and effective medication for managingtype 2 diabetes and is not generally recommended to be stopped unless there isa specific need to do so. My note- From wattsapp talk by a doctor is periodic visitto doctor for check up to reduce the power ofthe metformin and warned if not power reduced after a period blood sugar may fallvery low. Q8 Whatmeasures do hotels take to prevent non-guests from using the parking lot andairport shuttles? A8 Manav Rama, Save up to 90% on flightswith Mighty Travels Premium. Dec 26 Hotels take avariety of measures to prevent non-guests from using their parking lots andairport shuttles. Most hotels require guests to showvalid identification when entering the property, as well as when boarding theshuttle. Additionally, many hotels have security personnel onsitewho monitor activity in the parking lot and around the shuttle area. Some properties also use technology such as license platerecognition systems or key card access points for entry into certain areas oftheir property, including parking lots and shuttles. Finally, some hotels may even provide additional servicessuch as valet service or car detailing that are onlyavailable to registered guests in order to further discourage non-guests fromaccessing these areas of their hotel. Q9 Isit true that dumping a bucket of water into a toilet will make it flush withoutthe handle being pushed? A9 Raphael, A worthless student going tocollege. Fri Yes. Most toilets usesomething called a “syphon effect”, where there is a tiny tube underneath thetoilet. If this tubecompletely fills with water, the pressure will cause a force that pushes all ofthe water and waste in the toilet down the drain. The tube isdesigned such that a given amount of water is required to activate the syphoneffect. It doesn’tmatter whether the water comes from the tank of the toilet or from a separatebucket; there just has to be a large volume of water entering the bowl quickly.(If it enters too slowly, or there isn’t enough water, the tube will not filland the syphon effect will not occur). The whole reason the tank exists isbecause the rate of water entry necessary to activate the syphon is greaterthan what most household pipes can accommodate. For most modern toilets in the United States,approximately six litres of water must be poured into the bowl quickly to getthe toilet to flush. Older toiletsneeded either 13 litres of water, or for even older toilets, a mammoth 19litres of water. Washd own toilets,often used in Europe and Asia, flush differently, and some can flush with aslittle as four litres of water. My note- For stoolsreaching the septic tank there must be good slope. PVC lengthy pipes gives aslippery effect. Cost and effort of pouring more water will reduce getting struckof stools. Opening inspection points and making stools flow adding water andpushing will cost very much. Last time whenseptic tank was cleaned about 2 yearsback, after cleaning with machine, askedus to pour 10 buckets of water for cleaning pipes. But water did not reach theseptic tank. Charging forseptic tank cleaning was 1800-00. The persons said, they will check inspectionpoints and set right and said me to give Rs 2500-00. I simply agreed, problemwas set right opening 2 inspection areas and pushing stools, with allprotective arrangements. I gave them as asked 2500-00. But they said , itwas additional to Rs 1800-00, which had to be given to their owner. I paid theadditional amount of Rs 2500-00. Then onwards I flushat least 5 litres of water after use. Some stool may float with air inside, I pour buckets of water tillthey completely go out and clear water in the seater. Q10 Whatare some of the best train hacks for India?
