Virus ko artificial medium par culture nahi kar sakte. That doesn’t mean culture hi nahi kar sakte…. It just need a host, a living cell to multiply…. And that is y viruses are neighter living nor non living rather connecting link between them.
Question status moderate to difficult....no direct question. This time question was more deep explanation with basics. Some questions are pull from editorial concept. But very balance question. No Test series can make us profits.
Here is my take on cooker question:- If I go by general meaning of pressure cooker it would mean a cooker that uses pressure to cook the food. So it boils down to what all affects the pressure 1) area of hole 2) temp of flame (higher the flame temp higher is heat transfer, higher the pressure) 3) weight of lid ( more weight=more pressure) So ans- D Let me know what u all think
But the question is about the factors influencing the temperature. I think that's why weight of the lid should not be considered here. If it was asked like how fast the food can be cooked , then we can consider the pressure ( the weight of the lid ).
I don't think weight of lid will have effect because modern cookers have very light weight lids than normal one.. Even if we go by electric cooker, then weight of lid doesn't play any role. Rest like every time, upsc will again escape controversy by not releasing answer key.
The temperature of the pressure cooker will not depend on the intensity of the fire because each pressure cooker has a fixed boiling point ( Because lid is made keeping that in mind), if you give it more than that, it will come out as extra energy then it will depend only on lid and area so ans. 1 and 3 will correct according to myself
No, you can't say the temperature of the pressure cooker doesn't Depend on the temperature of the flame. I get what you are saying , once it reached the boiling point, we cannot increase the temperature of the cooker any further but before reaching the boiling point it is the temperature of the flame that brought the temperature of the cooker from zero to boiling point.
Mostly upsc becomes practical....u will get around 15 to 20 direct from practical where u need to apply ur logic to solve it rather it wont came by just studying books.....applications pe focus krna chahiye rather just doing everything from books by just rattafication or mug up.... Conceptual clarity must be there...then u will definitely able clear prelims
Sir end question ...speed of light is same only with one medium... When the medium is denser...the speed of light decrease...that also creates refractive index more....how it can be evaluated...because light travels in a straight line until there is any extra force...speed of light will be same in one medium... But when there is change in medium it differs... Also you can take black hole theory example
I also applied the same logic and found that only b options' info is correct but unfortunately for mapping distance of stellar objects we dont get any other medium than vacuum
Sir i think led light can produce light 360, but its easier to engineer LEDs to produce focus light, which doesn't mean that it cannot be made to produce 360 if and equipment application demands
Yes, but there is hardly or no medium at all when we talk about astronomical distances ,( eg, distance between planets, stars ,etc.). So lightyear is used only in this context.
Thanks SIR now I'm in class12. I want to prepare of upsc with my 1st year graduation. But I'm very frightened from prelims specially in csat. So I watch your video in free time. It is very helpful 4 me . THANKS SIR 4 THIS🙏🏾🙏🏾🙏🏾🙏🏾

Sir speed of light also changes when medium change.there is solid reason for different refractive index in the space. I think light travel is the right answer.
It is said for simplicity that light slows down in medium but photons themselves never slows down really..its a different mechanism...search about it ...

1) area of hole
2) temp of flame (higher the flame temp higher is heat transfer, higher the pressure)
3) weight of lid ( more weight=more pressure)
So ans- D
Let me know what u all think
lid and valve is different thing or same
My logic while attempting was exactly tge same. However no key that i looked so far claimed this as an answer
But the question is about the factors influencing the temperature. I think that's why weight of the lid should not be considered here.
If it was asked like how fast the food can be cooked , then we can consider the pressure ( the weight of the lid ).

Boiling point is same.... But transfer of heat and energy maximum due high flame... This is also come to my mind. So Ans 123..
Bahoot harad…. Debatable…
100% right bhai
No, you can't say the temperature of the pressure cooker doesn't Depend on the temperature of the flame. I get what you are saying , once it reached the boiling point, we cannot increase the temperature of the cooker any further but before reaching the boiling point it is the temperature of the flame that brought the temperature of the cooker from zero to boiling point.
I have put my rice in pressure cooker and kept atop a candle flame. Dont know why its taking forever to cook.

Sir my gs paper was good but I lacked in csat sir 😭😭
Very easy question
Speed of light varies with medium that's called refraction
I also applied the same logic and found that only b options' info is correct but unfortunately for mapping distance of stellar objects we dont get any other medium than vacuum
Last time i went to school we called it bending of light. And Speed of sound varied with medium, not light. Gosh, Science has advanced much.
Aaj nhi kr skte bt aaj se 10 sal baad to may be Pasible
