Plz solve this question

use P=(rho)gh
to find the pressure exherted by the liquid then...multiply the base area with it and tada...there you go youll have your answer i think it should be..

 

[Spidey21]

Plz solve this question

my guess is B....i dont know about what is the unit of the answer..
please do tell me if you know the answer...
do share it!!

 

[Fallen316]

Plz solve this question

first find the pressure of the liquid
P=density*g*height
then apply P = F/A
F = PA

The answer should be B .. correct ?

is it alright if you write outside the given space on paper?

 

[étudiante]

is it alright if you write outside the given space on paper?

yes, as long as ur within the BOUNDRIES around da paper sheet... (the rectangular box around the enitre text part of the page) and if u show where it continues from clearly

only if its one or two words . And try to refrain from writing in the '' For Examiner's Use Only '' column.

Mostly the space is enough . Stay brief . Sciences are not English . Short phrases , as long as they convey the meaning , work fine .

Are you sure?
I think IGs allow any amount as long as it's on the same page AND is clear!

Back to the topic everyone!

Thanks! I was looking for something like this but you know... extremists (like the one below) loves to give cheap replies and think he/she just made a breakthrough


Yeahp! Funny you! :-/

Okay okay , don't make the thread go Off Topic ( My fans just can't leave me alone can they )
Back to Ask Question . Multixamza01 Answer questions . Everybody gets to eat Cheetos at night

LOL what a self-obsessed day dreamer!
No make that doritos way better.

Anyways, i wanted to know TO WHAT EXTENT can water be compressed.

until it says '' Multixamzao1 is Awesome''

It's water . It can be compressed until it becomes ice. then it breaks , and we have ice shavings.
Store ice . Summer is on the way!

Pressure ap laa key de rhe hain? i got ACs
But seriously, ANY liquid can be compressed until it becomes solid?

with VERY high pressures it is theoratically possible...
but generally the pressure required is SO high that liquids are considered virtually incompressible

compressing , means the particles come closer . I used my head and yeah i think that does make sense .
