Hey i am done with AS am in A2 nowdid u work out jun 2011? cud u help me out with q2? N i didn't get what is the difference between quantity and unit
hmmm, for A, B and D it certainly helpedHey i am done with AS am in A2 now
but yea i sure can help
look....quantities are like mass, length, time
their units are kilograms, metres, seconds
so basically in the qn u asked, the qn wants quantities not units
so option A - ruled out coz it has 'metre' ( which is a unit)
option B - the statement itself is wrong, pd is not equal to energy per unit current
option C - the correct answer since it is the right definition and uses only quantities
option D - ruled out coz it has 'second' (which is a unit)
hope that helped....
hmmm, for A, B and D it certainly helped
bt wat i still don't get is why area isn't a unit, bcoz its so close to cubic metre..
or do you mean they require only SI units? :O
that took me quite a time, and then it said my pc does not have an allowed extensionPost z question directly- Make a print screen
omg! thXx!! now i got it thnk u vry muchokay look i am not sure about the SI unit thing, but area isn't a unit, a unit woud be someting yu write after a quantity, so for eg i can say 250kg, 300seconds, 500metres, but can i say 400areas? noo i can't......area is measured in metres.....not vice versa....hope you get it.....
what computer do you use? if it's normal pc or laptop - there's a printscreen button on the right of the keyboardthat took me quite a time, and then it said my pc does not have an allowed extension
how do u usually print screen?

Hey guys, I've got some mixed signals in doing Q 1 / part B of w02_qp_2.
I don't know why p/ro = m^-1 s^-2 / kg m^-3 which is equal to = kg^-1 m^-4 s^-2,
and then the marking scheme says square root of p/ro = ms^-1 <==== How?!?!?

Thanks in advance.
Well, its relatively easy. Displacement is defined as the distance from a fixed point in a specified direction. We're all clear, right?how do i do qs 2a(ii) The mark scheme is confusing me.
