Beingcompilation there may be errors Q1 Whathappens when car battery cables are wrongly connected? A1 Timothy Mauch Corvair owner and researcher. August 6, 2017 My step-father did it to my new ’86 Dodge Daytona while I wasat sea (actually, he connected jumper cables backwards after my wife left theheadlights on and drained the battery). The “fusible link” that was supposed to protect the car blewso violently that it caught that part of the engine wiring harness on fire andmelted everything on the wheel well. Fortunately, the car was under warranty, and the dealerdecided to ignore the obvious fact that the fire was self-inflicted, Maybe hefelt bad that my wife was home alone while I was away on a submarine. The one smart decision my wife made afterwards was to never,ever let my father-in-law pop the hood again! Q2 Why arewe not supposed to (according to some) touch plants or pluck leaves duringnight time? 2 Answers PallaviPande, Founder at DTOCS LLC (2018-present) Answered May 15, 2020 It is a very common belief among a lot of people that theyshouldn’t pluck leaves during nighttime because the tree is supposed to besleeping. No, no one has ever actually heard a tree snore after 9 pm everynight. It is just an easilyrelatable analogy to discourage kids from venturing out at night around bushesand dark shades of trees. The real reason behind this has nothing to do with treessleeping. As we know, green plants use sunlight during the day to performphotosynthesis. This process involves them taking in carbon dioxide from theenvironment and creating glucose molecules and releasing oxygen as aby-product. At night the process is reversed. Now the trees, just like us, takein oxygen to release energy from the glucose they made during the day andrelease carbon dioxide into the air by way of respiration. This is why the air around atree has a higher concentration of carbon dioxide than oxygen at night. Thiscan be harmful to any person breathing the air. Also, trees and densebushy areas are a natural habitat of insects and snakes, most of which become more activeduring the night and are more often than not dangerous. These are the major reasons why you shouldn’t get anywherenear bushy areas at night, let alone go near enough to pluck leaves. And as for the matter of plucking leaves, you shouldn’t bedoing that irrespective of the time of the day. Just like you don’t likeanybody plucking your body parts off, the plants don’t appreciate it either. 2ND ANSWER-Saptarshi Majumder , Masters Chemical Engineering & Particle Technology, Indian Institute of Technology,Kharagpur (2017) Answered June 2, 2016 There won’t be anything huge happening but the real motive behind this is notto disturb someone while they are sleeping. As you would know that during the presence of sunlight, theplants and trees perform photosynthesis. It is kind of that they are doingtheir work during the day. But at night since there is not sunlight, the tree is kind of sleeping.Thus it is meant not to disturb the sleeping ones. Note: You should never pluck leaves, whether it is day ornight. Q3 What isan 'island platform' in railway stations? A3 Dharani Sathwik Ram Interested infunctioning of Indian Railways Fri A platform which has railway tracks on its either side iscalled an Island platform or a center platform. Most commonly in Indian Railways, island platforms areconstructed between the main lines. Image: The island platform is surrounded by the main lines andthe loop lines run beside the side platform. Larger railway stations may have multiple island platforms inbetween two side platforms. Advantages: More efficient use of space as the passengers travelling inboth the directions can share the platform area and the Vertical CirculationElements (VCEs) like stairs/lift/elevators. Facilitating the passengers to change the trains running inopposite directions eliminating the need of an additional platform and aconcourse level. Disadvantages: VCEs are constructed in the middle of the platform reducingthe footfall area on the platform for a distance. Reduced wall area for ads or information display boards. (IRpoint of view). Apart from the island platforms, there are other types ofplatforms in the Indian Railways. Side platforms. Theplatforms which are generally aligned to the boundaries of railway station are sideplatforms. Occasionally these are found next to Bay platforms as shown in theabove figure. And most commonly, 2 side platforms are present in a givenrailway station and are numbered 1 and N (N being the total number of platformsin that railway station). Bay platforms — Theplatforms where railway track terminates at one end are called Bay platforms. These can be found atChennai Central, Howrah etc. Flow through platforms— A single platform which allows the train traffic to pass through it such that passengers canalight/board the train from both the sides. This reduces the dwell time of thetrain on the platform. These are majorly found in places where local traintraffic is higher. But these are expensive to construct and maintain. Note that the train is not running between two platforms,rather it is running through a single platform. Q4 Whatare some simple habits to help you burn belly fat?

A5 Devasena Bhakta Researched Hindutemples Sun Goddess Meenakshi is said to have a dusky complexion (ShyamaVarna) In South Indian tradition, turmeric is used as a cosmeticproduct by both married women and unmarried girls When Sri Meenakshi appliedturmeric, Her Shyama Varna is said to have taken on an emerald hue The statue of Sri Meenakshi at Madurai is made of a greentinged stone - Maragatha Kal Q6 Whichairlines in India provide free meals (domestic routes)? And how good is thequality and taste of food? A6 Shaunak Bhattachharje Visited 17Indian States | 7 Countries | 4 Union TerritoriesSun Nothing comes for free. The cost of the meal that is provided is already included in yourticket. In India, only twoairlines provide complimentary meals - Air India and Vistara. Vistara has some conditions, however. They will be servingmeals only if the distance or the time exceeds a particular number, I am notsure about it though. AirIndia, on the other hand, will provide you with a meal even if it is a half anhour flight. I have not travelled with Vistara yet and therefore cannotcomment on their food quality but having travelled on Air India extensively in the last threeyears, in my opinion, the food is tasty. While flying 30,000 feet abovethe ground, your taste buds lose the ability to taste but still, the food, atleast according to me, tastes good. The above picture is what was served on Air India while I wasflying from Kolkata to New Delhi this Wednesday. It had paranthas, rice, avegetable curry, a sweet, pickles and curd. As I mentioned about the clause of Vistara, which servedcomplimentary meal only if the flight distance and time exceeds theirthreshold, Air India, on the other hand, do not serve a meal on their ATRflights that are operated by Alliance Air. Before Covid, they used to provide a food packet but that hasbeen stopped now. While flying on an ATR on Thursday from New Delhi toChandigarh, I was so eagerly looking for the packet but after deplaning I gotto know that the meal services have been stopped. Q7 Can you tell about TDS levels of water? A7 Thedrinking water that we get today is flushed with hazardous chemicals from thedifferent water treatment plants. As a result, the natural minerals present in water are taken away.In such a situation, it is essential to use the proper filtration processes toremove the contaminants and make water safe for consumption. The main contaminant present in water is total dissolvedsolids (TDS) that are left in the water after the normal filtration process.Contaminants that arelarger than 2 microns are termed as total dissolved solid. Drinking Water TDSChart One of the importantquestions that many people have in their minds what is the acceptable TDS levelin the water. To help you out, we are listing two tables which discuss the palatability quotientand acceptable TDS level. TDS Level in parts per million (ppm) Palatability Quotient Between 50-150-Excellentfor drinking 150-250 Good 250-300 Fair 300-500 Poor Above 1200 Unacceptable Is low TDS waterharmful to Human Body? TDS present in water is not a measure of any singlecontaminant and so is generally not regulated as a health issue by manygovernment agencies. A high TDS level, however, can affect thetaste and odour of water. The Environmental Protection Agency in the US has set themaximum recommended level of 500 milligrams per litre (mg/L). The TDS level in water can be determined with the help of aTDS meter. A TDS test helps in determining the total amount of dissolved solidspresent in water. However, it doesn’t identify any individual compounds, thesources. As a result, it is essential to conduct some additional tests todetermine the contaminants present in water. How Much TDS in Water isGood For Health The table mentioned below provides a permissible range of TDSin drinking water and reasons for why the TDS level mentioned in water is notacceptable for drinking: TDS Level (Milligram/Litre) Remarks Less than 50- Unacceptable as it lacks essential minerals 50-150-Acceptable for drinking.The TDS level isideal for areas where the water polluted by sewage or industrial waste 150-250-Good. Thewater is ideal for people with cardiovascular disease 250-350-Good. The water isideal for people withcardiovascular disease 350-500 Fairly acceptable 500-900 Lessacceptable 900-1200 Leastacceptable. Avoid drinking water which has a TDS level of 900 1200-2000 Water isnot acceptable for drinking. Above 2000 Unacceptable According to the Bureau of Indian Standards (BIS), the upperlimit of TDS level in water is 500 ppm. The TDS level recommended by WHO, however, is 300 ppm. Ways to Reduce or Remove TDS in Water 1. Reverse Osmosis(R.O.) Reverse Osmosis removes TDS by forcing the water, underpressure, through a synthetic membrane. The membrane contains microscopic poreswhich will allow only molecules smaller than 0.0001 micronsto pass through. Asthe molecules of dissolved metals and salts are large compared to the water molecules,water squeezes through the membrane leaving the metals and salts behind. My note- Though called membrane it is a closed filter with inlet and outlet 2. Distillation The process involves boiling water to produce water vapor.The water vapor rises to a cool surface where it is condensed back into theliquid form. The dissolved salts are unable to vaporize and remain in theboiling solution. 3. Deionisation (DI) In this process, water is passed through a positive andnegative electrode. The ion-selective membranes enable the positive ions toseparate from the water and move towards the negative electrode. The end resultis de-ionized water with high purity. However, the water is firstpassed through a reverse osmosis unit first in order to remove the non-ionicorganic contaminants. So, which Water Purifieris best? One of the important factors that you need to consider whenlooking for a water purifieris the TDS level. Depending on the TDS level, you need to decide whetheryou need an RO, UF or UV water purifier. To make your work easy, here’sa table that will help you understand which water purifier is ideal for aparticular TDS level. TDS Level Typeof Purifier 0-200 UVWater Purifier 200-300 RO+UV water purifier 300-500 RO+UV+UF Areas that receive water with a very high TDS level arerecommended to use water purifiers that use a combination of RO+UV/UF with TDSController. The combination of various water purification technologies removeschemical, dissolved as well as physical impurities from water to make itsuitable for consumption. Why Should You Keep a Check on the TDS Level? There are a number of reasons why you need to check the TDSlevel in the water. Some of the reasons are: Taste and health High TDS level alters the taste of water and makes it salty,bitter, or metallic. High TDS levels also indicate the presence of toxicminerals which is hazardous for health 2nd answer ChandreshHirani Answered September 18, 2017 TDS Controller for RO is available in market at around 200 to300 Rs based on quality. It has 2-inlet and one outlet. You have to connect oneinlet with RO Purified Water which has lower TDS. And other Inlet needs toconnect with the same which you connected with Membrane input. And output iscontrolled TDS. You can change output TDS by rotating its screw clock-wise oranti-clockwise. All the above QA are basedon Quora digest to me on 07-09-2021.
