Physics 31, If 15 more minutes were provided

[Alex10]

correct but there was a conversion because height is in mm and denseity was in m cubed

Yes sojiro converted it from 250mm to 0.25m.

 

[ahmed soliman]

yes i know it will be 250mm divide 1000 =0.25 m then used in the equation

i divided 250 by 1000000000 by mistake because i thaught m cubed s0 1000*1000*1000

is there any chance of getting A* if i get 50 in P3, 35 in P6 and 35 in P1????

due to the curve in 2012 nov yes it is A* but this year i think the curve will be increase

okay now im scared

 

[Mohab88]

okay now im scared

practice well for paper 1 and not lose more than 2 marks

 

[980coolguy]

[Mohab88]

well, okay.....i'll try my best nd gud luck for ur exams

good luck for u 2

i divided 250 by 1000000000 by mistake because i thaught m cubed s0 1000*1000*1000

the height is not calculated as volume (cubed) no it is just by 1000 any way good luck

they said the pressure of the gas and not the total pressure so u have to subtract! but i didn't do this

 

[Mohab88]

they said the pressure of the gas and not the total pressure so u have to subtract! but i didn't do this

yup pressure of the gas = atmospheric pressure + pressure in part A it is a formula so if u did this its correct answer

 

[Sojiro]

hahhaha no it is adding the ppressures not subtracting

 

[silentkiller97]

hahhaha no it is adding the ppressures not subtracting

if the liquid column would had been higher to the right side where atmospheric pressure was acting then you would had been right. here the pressure was certainly lower than atmospheric pressure as the opened side exerted atmospheric pressure which forced the liquid to rise from other side
