I too feel that statement 1 in coriolis force question in wrong.In ncert it's clearly given that 'coriolis force is directly proportional to the angle of latitude' which means that angle of latitude is the determining factor. However upsc's statement says that 'it increases with increase in wind velocity's.This will be wrong because for example at equator even if wind velocity increases, coriolis force will be zero as it depends on angle of latitude and not wind velocity.
@@brockviper6846 arey uss line mai likha hai deflection due to coriolis force (naa ki coriolis force itself) increases with increase in wind velocity. ispr hi debate hai.
It is not saying PAF are found in drinking water instead the essence of statement is that the material which is used to store drinking water food and food packaging material are contaminated by PAF material .
No bro it is not asking about material stored it is clearly saying food and drinking water which makes the first statement wrong widespread is highlighting huge range
Pfas is widespread in drinking water just google pfas + widespread also coriolis force increase in magnitude with wind velocity. Imagine rotating in a circular rotator the more the velocity the more the deflection and more coriolis force. Although wind velocity is not impacted but the amount of deflection is increased which is coriolis force.
I have proof from NCERT on coriolis force question. It directly says deflection (& not the force) increases with increase in wind velocity. I can send u screenshot. Contact me on telegram.
@@UpscMainstream but sir deflection is directly related to coriolis force na. The more the coriolis force the more is deflection. Also where rotation is prominent like at poles coriolis force is maximum and where there's flat surface its zero at equator. It reveals that deflection of wind is the magnitude of coriolis force being exerted . Thats why wind deflect in both hemispheres as per coriolis force. You are correct when u say that in ncert its written that wind velocity affects deflection. I push this further that what you are saying deflection is nothing but coriolis force. Becoz deflection is perpendicular to the pressure gradient and Coriolis force is also perpendicular. Also at equator deflection is zero so coriolis force is zero. So deflection and Coriolis force are the 2 names of the same concept
Coriolis force is a pseudo force. Similar to the centrifugal force . It depends on the amount of velocity in a circular motion. You can crosscheck sir. All the best for future endeavours
@@Plan_IAS nice explanation yaar, I agree 👍 Rest we leave on upsc to decide. I just saw ur channel nice initiative. Maybe we can get connected on telegram?
Upanishad question is also wrong. Multiple Upanishads mention the Puranas. ANy one who has read them will know that the original composition of Puranas was before the upanishads. Eg: From Brihadaranyaka: "As from a fire kindled with wet fuel various kinds of smoke issue forth, even so, my dear, the Rig-Veda, the Yajur-Veda, the Sama-Veda, the Atharvangirasa, history (itihasa), mythology (purana), the arts (vidya),........" Those who actually READ upanisads would have got this question wrong(if UPSC is going to give a gravely wrong key)
""""Water pollution with PFAS substances is widespread PFAS substances contaminate coastal water (Bangla- desh, Japan, Malaysia), sediment (Bangladesh, Indo- nesia, Japan), river water (India, Japan, Nepal, Thai- land, Vietnam), ground water (India, Japan, Thailand, Vietnam), and drinking water (India, Japan, Malaysia, Thailand, Vietnam). PFAS pollution includes PFOA contamination of the Sundarbans mangrove area, a UNESCO World Heritage Site. Wastewater treatment plants have been identified as PFAS pollution sources in Japan, Jordan, Thailand, and Vietnam """" Copied from UN report
Uranium is also found in different regions, different countries of world but that doesn't mean it is widespread. Widespread means everywhere So your explanation is not satisfactory
@@ankurblue3877 i respect your observation may be it can go anyway. I am also an aspirant like you. 3 factors which lead me think that this is correct were: 1. Widespread doesnt mean everywhere. It just means its spread is big. Also UPSC used a standard language...when upsc uses standard language ( here it used ," found to be " ) whenever upsc ornaments the word before the keyword they are generally correct. Similar you can observe in niger seeds ques in 2023. Upsc generally incorrect those statements where keyterm is either at start or at end like omnivorous ques Squirrels 2. They are called forever' chemicals also there are news articles of its widespread in US. Since Upsc also framed one question on US debt default may be they found the similar news in that newspaper related to us 3. And if you are saying its not widespread, then can we say its not widespread.? No we cant say its not widespread. If term used would have been pfas are everywhere in water or in every water body then it would have been surely wrong But widespread generally i feel this time upsc will correct this also keeping in mind that this time upsc deliberately made all statements correct in many quess like part wala , also money bill wala article 100% central funded
@@UpscMainstream This takes some good skill. Really impressive! I attempted only 76 Qs despite my bad accuracy. Do you think, that's why I messed up my GS paper? I'm scoring around 78 marks. I should've attempted more, right?
@@tusharshukla5381 no you can't, because if wind speed is more in the equator can you say that coriolis force is more in the equator? Because we know that coriolis force is 0 in the equator irrespective of wind speed.
@@stg4992 @stg4992 absence of coriolis force at equator was the reason why wind not deflected from their path at equator but if there is coriolis force then increase in wind speed increase the deflection that means at same latitude where pressure diffrence is high then the coriolis force acting on it is higher
@@sanketsarode9005 Sir predictable means is baar answer predict karna (answer key banana) asaan hai as compared to last year. is baar coaching ki answer key aur UPSC answer key mai 10 questions ka antar nahi aega jo last year aaya tha. Just listen carefully then comment 😇🙏

Bro mera physics optinal hai 2m (w ×V) ye velocity dependent hota hai. Ek baar net se coriolis force ka formula check kar lo bhai internet se. Thora sa toh research karlo video banane se pehle, aise hi uth ke kuch bhi bna dete hai.
Abey Bhai pehli baat sb logo ka physics optional nahi hota...doosri baat mene sirf wahi question cover kiye hai jinpr log debate kr rahe hai (mai nahi) yaa different coachings ne different answers diye hai. Phele video poora dekho (part 2nd bhii hai) phir kuch comment krna. Aise hi muh utha kar comment kar dete hai
@@UpscMainstreamwahi to sab lok to nhi padhenge physics ye log bakar krne ke liye apna answer sahi krne ke liye kuch bhi explanation leke ayenge ultimately upsc maregi hi 😂
