Even when height is different?[/quote]
Yeahup . Gravity only changes when masses , distance . (according to my sci journal)[/quote]
Crap 5 marks gone- :stupid: -
OrangeJuice:
You mean the MCQ one ? Its the same . Gravity dont change .
Even when height is different?[/quote]
I thought it is gravitational energy that will change when the height is different? I thought gravitational force depend on mass? :scratchhead:[/quote]
That was how my DD explained to me too when I thot height affects the gavity lvl....[/quote]
Heheh ! Your DD is correct !

Is there any more questions in the booklet A that need to be discussed?.. I forgot all of the questions.. Haizzz.. Only question 1

I just want to clarify with all of you, is it true that there is more weightage on English and Chinese? My friends and their mummies say that English+Chinese=200%, Science is 50% and Maths is 50% as well…
Oh yes, I want to ask about question: ‘Which set-up should he use as a control’
What did you put? -
On the question about the force of gravity, my view as follows.
The force of gravity can change and it decreases with altitude. When the ball is kicked, there will be a change in altitude, resulting in a change in this gravitational force. -

Is it about the carbon dioxide question?I just want to clarify with all of you, is it true that there is more weightage on English and Chinese? My friends and their mummies say that English+Chinese=200%, Science is 50% and Maths is 50% as well...

Cher told me all 100% each . I put the one that have the substance which removes oxygen .I just want to clarify with all of you, is it true that there is more weightage on English and Chinese? My friends and their mummies say that English+Chinese=200%, Science is 50% and Maths is 50% as well...

Anyone remember the last Question for booklet A? :scratchhead: :scratchhead:

Little Brown:
but in transpiration, only a little amount of water is given out. so how can that little amount of water, in gas form, can fill the water (liquid)? can anyone tell me why it is not water if the answer is carbon dioxide though im not so convinced?
The water that is used in the photosynthesis reaction does not come from transpiration, if that's what you mean.
The water is from inside the photosynthesizing plant cells, where all the chloroplasts, enzymes etc are.
