Oh alright ....

lol koi nai saaron ka yahi haal hay

The answer is 1.61.This is because at 5 cm the reading is 1.61 so 95 cm=100-95=5cm,so at 5cm the reading is 1.61

thanku

 

[beeloooo]

Oh alright ....

yr pehlay physics , chemistry hujanay do aap !! abi se maths na yaad krwao

Yeah but thats the only thing in maths which I dont like " to learn".. :S

LOL OHk end it now only

 

[MustafaMotani]

why metals salts of like Ca, K, Na are made only by titration rather than other

no body does

thanku

np

 

[malay]

what have u done
mass of ammonia was asked not nitrogen

ok m wrong!!!!!
but u can do it this way for ammonia aswell
n yeah thanks for the correction

all of there oxide and hydroxides are extremely soluble

 

[MustafaMotani]

no body does

how u learned the matrices of transformation.. ??

 

[MustafaMotani]

all of there oxide and hydroxides are extremely soluble

so I kn0w that .... ans of this should be like metals cannot be used individually coz they are highly reactive and difficult to be kept in pure form.. ?? am I right

 

[a.abid]

how u learned the matrices of transformation.. ??

waisay why r u asking for matrices? abhi poora aik week hay maths kay liay physics aur chemistry tou karlou

Ok so I know Its off topic but its still subjectual...
have u got any easy way to learn transformation matrices coz it eats lot of time doing experiments with cordinates

yes i have a very round about way, but i will post it after our this deadly week!!!

coz mjhey ek saal hogaye hai lekin mein matrices yad nhe huwe...
