guys....to no offence.one thing is evident that u didnt read the book

pressure does not depend on the area or diameter of the tube...

if it would be 50 times wider it would still be da same

the ans was b

dude!!!!

above the liquid  is vacuum, its not effected by pressure.

so height will be lower not the same

the ans was b

same level.......b

here is MY EXPLANATION......

barometer is used to measur da pressure...and since IT measures using mercury which is a liquid...

u will use the formula p=h x d x g......agreed.......

now pressure in liquids DOES NOT DEPEND ON AREA OR DIAMETER...

IT depend upon HEIGHT and DENSITY.

so wat ever the diameter the pressure will be the same.....


this is the best explanation i can give...
hope u understood well...

The barometer question. The answer is B, it is the same height. Stubborn people can google it.
The echo question. The correct wall is the one ALL THE WAY at the right near the top.
The fuse and circuit breaker. Both are on the live wire.
The fuse. Its 1A.
The meter rule is the one with 3 decimal places. 0.761m.
AND im pretty sure the fire one is C, the air is less dense at higher temperatures.
