Title: Physics Paper 1 MJ2009 + Mark Scheme
Post by: Fibonacci on June 20, 2009, 11:09:52 pm
So people, here is the MJ09 Physics Paper 1. Sorry I made you wait.

I made up a Mark Scheme for the Paper but there are some that I'm not sure off so those are in red colour. Maybe we can discuss and reach a definite answer.

See Ya,
Peace

Thanks again. Dont care where you get 'em from, as long as anyone can get 'em here.

I actually got them from my teachers. They are allowed to give us. I got'em and scan'em for the good of society.

(and the final pages + MS)

its D

no no ,, i think the answer is C ,,, cuz after evaporation the most energetic particles have escaped taking the energy wid them . which in turn decreases the temperature of the remaining liquid .. its just like an after shave which after it evaporates leaves the skin cool ...

well i personally put down C ,, ppl people say its B cuz some crossectional area bullshit ,,i just dont get how its B , i think its C
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: astarmathsandphysics on June 21, 2009, 12:59:09 pm
It is B. The cross sectional area is different but the pressure is the same using P=pgh(=atmospheric pressure)

The down force at the base of the column of mercury must be equalt o the force op

pghmercuryA=patmosphereA

The A's cancel.

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
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: astarmathsandphysics on June 22, 2009, 09:27:22 am
B is right.
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: IG_ICE09 on June 22, 2009, 09:37:18 am
isnt 32 wrong? both the fuse and circuit breaker shud b placed at X right? so the answer is not B
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: astarmathsandphysics on June 22, 2009, 10:23:38 am
Both fuse and breaker should be places at X.The answer is A.
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: m3ani on June 22, 2009, 11:51:39 am
isn't 18 B? because they are smoke particles and not air particles so they diffuse

It is CThe file creates a convection current becuase it heats the air, which becomes less dense and rises. The smaoke particles are drawn up by the convection current.

Thanks a lot  ;D and the fuse and circuit breaker should be placed both at X ............. and about the mercury level i think (not sure) it will be of the same level bcoz the atmosphiric pressure stays the same so 76mm of mercury and the formula states that p=density*g*height

i appreciate ur hard work..rlly thx for the mark scheme but before publishing it plz check it because there is alot of mistakes in the mark scheme
so modify it plz thx

I dont agree. People can query the ms, and the answers will be correct within a week. Just read the thread.

Was extremely hard!! bloody death defying lol... it really pissed me off actually, and has got me very worried, just hope the grade boundaries would be low this year.....

For question 10, isnt the answer "A" and not "C"??.... as he runs accross the beach, then climbs at a steep incline...surely takes more power, than to just run up the slipway.. Please confirm!

Thanx

hmm
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: IGs on July 06, 2009, 09:35:03 am
my frnd just check which answer has the least time and it would be answer becz as u knw time is inversely proportional to power..so decreasing time will increase power
Title: Re: Physics Paper 1 MJ2009 + Mark Scheme
Post by: SGVaibhav on July 06, 2009, 05:02:40 pm
that does not help, because the distance is different in both case.

"my friend"... my bro who just got his A in A level physics said my answer "A" is correct!..

Its simple logic By the way, how can it be anything to do with proportion, if distances are different
