200 g

What did you write for Q8 for the above paper ??

C. 200g ..
100% sure about it
cause when a load of 100g is kept .. there was an extension of 10cm
therefore when you put a 200g .. its will be double ( 20 cm ) + 10 ( original length of spring ) = 30 cm as shown on the figure

ON ON ON

there was another question about dispersion of red and violet light ? wat was the answer for that?

i need to know the answer

ON ON ON

how is it ON ON ON ... the middle lamp wasnt a complete circuit? how current will flow?!
i answered on off on

Speed of violet light decreases more

I think there was a same question from this paper http://www.xtremepapers.me/CIE/Cambridg ... 5_qp_1.pdf question 9 ... there was something else instead of transformer given in the answers .. you guys remember it ?

The answer is motor

Correct . I'm wrong about lamps as I put ON OFF OFF , wrong for sure...made mistake about loads also , instead of 200 I put 150 , damn.

I put 300g. -_-

Current cant flow through the middle. Current takes the easiest route. and besides its DC so it goes straight... It can just go UP and reach the cell as. RESISTANCE OF WIRE < resistance of current. Well never know its just guesses. BTW it will do us all a favor if we stop talking about it....
No one will be sad

 

[KareemXPF]

Lol.. yeah its better.
i got 3 mistakes for now.. i dont want more XD

No I'm sure the question said that it didn't need boiling water.
