[SherlockHolmes221B]

How did you guys do? ^_____^

Thank you for the reminder! I was just asking how did they find it, not discussing questions! ^_____^

Yeah I said it generally to all, because people will start posting the question.

 

[uzair shahid]

overall it was easy.

 

[kevinjohn]

was great...

 

[Yashagrawal57]

better than paper 3...

 

[colors]

Can u start discussing the ppr

 

[fatima hussein]

wat did you guys write for the first question was it B 2 cubes?

 

[God Help]

I wrote 4 cubes

 

[fatima hussein]

I wrote 4 cubes

How can it be 4 cubes? the first cube took up to 2 cm^3 so 2 more will take up 2 cm^3 until the 9cm^3,

 

[Alex10]

Yeah it was 3 cubes

 

[Lizzie P]

Yeah it was 3 cubes

No, it was two.

The question asked how many MORE would fit before the tube started overflowing, not how many in total.

The measuring cylinder was originally filled to the 3cm mark. Adding one cube made the water level to rise to 5cm, meaning that it had a volume of 2cm cubed. An additional cube would have bought the water level up to 7cm, and a further one 9cm. Adding a third extra cube would make the cylinder overflow, as it only had a capacity of 10cm cubed.

completely correct...

what did u guys right for that fuse question ...13 ampere thing
q no:34 if im right..
please tell me ..i am breaking my head

I think I put that the lamp works normally (option D, I believe?)

I think I put that the lamp works normally (option D, I believe?)

I wrote B (the fuse won't melt but the lamp won't work) because it says that the lamp is not faulty. That means it should work with only the specific power, not more than that. I'm not sure of my answer, though.

It would be handy if we could see the question again to be honest. My reasoning was that 3 amps is obviously less than 13, so in effect the fuse just acts a a piece of wire. I'm not sure of my answer either, however.
