did u solve the oil tanker question zishi ?

I got the answer by common sense, but finding a "pure" logic. You've to wait - I'll PM you as soon as I get it.

ya thats A...Zishi u dint anser that scale reading question

A

ya thats A...Zishi u dint anser that scale reading question

he did, he said C and i got that too from the second try. just woke up !
for the last question u posted, the answer is D

 

[Zishi]

A

ya thats A...Zishi u dint anser that scale reading question

I answered. It's C

why is the answer not C, also can someone show me the full working for the derivation of the expression in option D...

 

[hassam]

B

ya thats ryt cos we hav to double uncertainty in diameter

Wait for it. Trying to use a software to answer it clearly.

ya that was C bt y it cud nt be A that scale reading one

thanks zishi
