IG_ICE09:
hey u guyz my physics teacher ses the 11th answer is B , it remains the same, but ur ms shows C. but if u think about it -if u keep increasing the diameter of the tube will the mercury be at the same level for same pressure? that seems kinda wierd..

nyway if the answer is C im gettin 40/40!! but B may be right

astarmathsandphysics:
B is right.

IG_ICE09:
isnt 32 wrong? both the fuse and circuit breaker shud b placed at X right? so the answer is not B

astarmathsandphysics:
Both fuse and breaker should be places at X.The answer is A.

m3ani:
isn't 18 B? because they are smoke particles and not air particles so they diffuse
