They use two factors in bone mass densitometry - velocity of sound through the bone, and attentuation of the sound wave by the bone. More dense bone = faster speed of sound and more attenuation Healthy bone denser than osteoporotic bone. Therefore blah blah blah

It's actually a five year rule, but there is definitely going to be some overlap in what questions they select this year compared to the last two years. Count on a titration question being in there somewhere...

Yeah, I caught the 'display' bit at the end of that 8-marker just in time as well. With the bone density, the properties I put down were: 1. Different velocity in materials of different density. 2. Different attenuation in materials of different density both of which are measured in bone...

Need initial velocity of projectile, unless that ramp was set up at -10 degrees.

At least 80 *hopes really really hard*

It was better overall than what I was expecting. First couple of questions were really good :D , but the remainder were not so good :confused: . And that projectile motion question was purely evil. :chainsaw:

Yep, pi irrationality for the second part of question 8. :chainsaw:

relax, you're not the only one. but take heart... if you manage to get 5 questions out right, you'll get a really good scaled mark. though anything beyond that is obviously good too :) Good luck everyone.

That's just not right... *looks at sqrt(-1)* *bangs head against desk* :confused:

I think the cut-off mark (raw) for band E4 (the highest one) lies somewhere between 70 and 80.

Don't have one, but our maths class is only 6 people anyway, so we get all the help we need.

Our physics teacher did it himself. Then we played with the liquid nitrogen. Looks really cool when tiny clumps of nitrogen goes running off the desk really quickly, but never quite reaches the floor.

No more English! Viva Liberty! :D :D :D :D :D Now if I could only figure out extension 2 maths... :confused:

Ditto.

The motto of our school. We've been saying it all year, and I'll say it again: The Board of Studies are Tools. Seriously, in addition to the above stuff-up, that paper should have gone for 3 hours, not 2.
