Just a sec i'll solve the question n show u what they mean the same question right?

ya thnx alot

 

[étudiante]

ya thnx alot

I wasnt able to type it so i scanned instead

hmm ok shldn't the 0.001 be beside the volume of sea?

no, the pressure at sea level is 1 atm so thats why

 

[*Sandra*]

thnx alot ok in q(24) whn they ask assumption why the gas is nt an ideal gas? and jst 1 more last thng im soo sry i did it my ans came correct bt im nt sure abt the way i wrote the steps can u show me how u write the steps for jan 2012 Q(11)

ur welcome
I dint understand what ur asking abt the ideal gas sorry

sure, gimme 2 sec pls

in Q(24) they ask calculation then assumption so they wrote in the mark scheme tht its nt an ideal gas bt i didn kno y its nt an ideal gas

 

[étudiante]

U need to use the formula g = GM/r^2
if the field is 6 times greater then the radius will be (6^2) = 36 times greater

oh ur asking abt the assuumption? Well there is no ideal ideal gas since there are forces between the particles n stuff

ok bt the point im confused of nw is whn they ask ths is greater than ths in like 6 times so the 6 shld be beside the g 4 earth or moon?

ahh ok thnx

g beside the moon The g on moon is less because its mass is much smaller

 

[étudiante]

ahh ok thnx

no problem ur welcome

 

[*Sandra*]

g beside the moon The g on moon is less because its mass is much smaller

ok then y in the pressure que the 0.001 was beside the sea? im really nw confused in these

 

[étudiante]

ok then y in the pressure que the 0.001 was beside the sea? im really nw confused in these

u need to read the question carefully n think Even if u miss it in the question, u know that g is less on the moon, and u know that pressure decreses as we go up Just read the question again n see if ur answer makes sense

thnx alot and ur doin phy or bio nw?

 

[étudiante]

thnx alot and ur doin phy or bio nw?

ur welcome
Biology

 

[*Sandra*]

ur welcome
Biology

u finished ur phy?

 

[étudiante]

u finished ur phy?

U think? I'd be jumping about if I had

I have Astrophysics left still, the Stars Life cycle part and a bit of gas laws... wat abt u?

i ned 2 revise 4 hubbles constant and also stars a bit. i still hve sme ques's im unable 2 solve and nuclear physics lil only and thermal phy also i hve 2 read once again and thts all wat i can do
