Hi,
Just spoke to DD.....She found the science paper relatively easy. Couldn't get more details from her now as she's at her friend's house now. Hopefully, no careless mistakes, esp. for MCQ. :xedfingers: -

:thankyou:stickyz:
What about the soil particles one (the one about pouring water through it)? Anyone remember your ans?
My ans is : there are more air spaces in Set-up A than in Set-up B so the water can flow through the large particles faster than the small particles and thus the amount of water collected.
Phew! Got it amost like yours! Thanks!

There is a question that is abt the control setup …may i know wat the answer? Is it 1 or 3 ?

My ans is : 4cm. After the loads were added and removed, the spring extended by 1cm, which makes it 4cm.The last question (booklet b)? About the spring one.
spring R-add loads to it then remove loads from it.
b) If the original length of spring R is 3cm, what will the length of the spring after all the loads are removed? Why? (rough idea of the question)
Help and thanks! -

I wrote: 4cm. After the loads were added and removed, the spring will extend a little more, so it will be 4cm. Thanks!

then it should be circle right..as firstly the small square cardboard ball not going to have any effect..though the 3 rd object which is a square cardboard, has the same height as the ball, it is within shadow of the cirle metal ball..
based on my son's memory....he drew out the pic for me.Verysuperkiasu:

How did you manage to see the question ?
light source--->small square cardboard---->metal ball--->bigger square cardbord but same height as the metal ball--->screen (all these are in side view profile). His answer is a square - (the square blocks the metal ball since they are of the same height).
< O X... :roll:[/quote]
my dd says in front of the light source there is something like a wall with a hole in it so when she drew the line starting from the hole, the metal ball's shadow will be cast on the screen.Her answer is the circle. -
