[ Official ] How was the Prelims 2021 paper?
How was the paper guys ?
Carbon monoxide answer will be most probably 2&3 only because u people are focusing on word “MAY” only and not on word “LETHAL”. If I say may release than even .00001ppm makes it right but if I say may release lethal than it must breach lethal amount which is not the case
Bro aap itne sure ho ki not even a single incident kahin pe exist karta ho jahan pe copper smelting se lethal co release nahi ho sakta hai .

If in astronomical aspects all the mediums are considered as vacuum only then d would be correct choice but if we consider the atmosphere around earth here it will have bearing on speed of light as well.
Light travels at a constant, finite speed of 186,000 mi/sec. . this is given in the website of nasa How "Fast" is the Speed of Light? (nasa.gov) now its your choice whether to trust nasa aur "do take ki sasti lucent"

Cutoff would be 96+-2

i agree with you boss, though i marked all of these i.e. D, i am always open to getting corrected and enlightened

Bro thora sa time dekarke wahin pe nasa ke website pe hi light year ka concept dekh lete aap

Now for the time being let me tell this very honestly even if we assume light speed to be constant if we have to find out the distance between the objects light has to travel in straight line otherwise simply knowing speed is constant does never help to get the actual distance.what if it is having curvilinear path even then we would be able to use distance as speed*time this is not the case brother….while using the formulae distance=Speed*time it has to be specifically straight line trajectory other wise this formula won’t be working.
