QUOTE(zltan @ Nov 29 2006, 04:26 PM) Wasn't the W already 10cm or 20N? How can the tegangan tali be less than that? The 20N is spread over the two ropes so each rope would definitely have less than 20 N in weight. Besides, if both of the ropes receive more than 15N, they would break and that also means the exam setter must have two broken paintings in his house   |

holy shit...i put atau...but in real life...if u press both butoons the lift aso work...rite?
btw...the spm std should b low...therefore i opt for atau considering the x-atau is too complicated..lolz This post has been edited by Pipity: Nov 29 2006, 04:29 PM |

QUOTE(fadhilah7 @ Nov 29 2006, 04:26 PM) i think u rite how about if one fella press up on floor 1 and press down on floor 2? lolxDshould be X ATAU coz...when 1 1 n 0 0 the output is zero as the Q said apabila salah satu butang ditekan..baru lif akan terbuka don't tell me the lift wont move at all.. haha |

QUOTE(Loongy22 @ Nov 29 2006, 04:23 PM) Problem is, which way does the lift go when both buttons are pressed? Yeah, that's the reason why I put X-ATAU. System malfunction! Haha. As for the keseimbangan daya question...well, the question stated that the tali can only hold up to 15 N, so anything more than that it will snap. So logically, your answers for T1 and T2 should be less than 15 N. |

QUOTE(Glassy @ Nov 29 2006, 04:26 PM) Yikes. Keseimbangan daya I'm not sure. I wonder if my answer is correct... Yes, so arrows will be going 1 whole round in a triangle.Daya paduan = 0, correct? So each arrow must be pointing to the end of the next arrow. For the first one, I drew a segi tiga sama kaki with 30 degrees each, and the remaining sudut cakah was 120 degrees. The length of my T1 was 5.8 cm. Second one, I drew a segi tiga bersudut tegak [45 degrees for the other two angles] and the length of my T2 was exactly 7 cm. The W [symbolizing the weight of mirror] should be 10 cm, because it is 20 N in weight. How did you guys draw your triangles? Anyone did the same as me? For my first, I draw a segi tiga sudut tegak with 1 90 degrees, 1 60 degrees and 1 30 degrees. For the 2nd, I draw the same but with 1 90 degrees, and 2 45 degress. I got like 20+ N for both of them for tegangan tali. |

In real life, I find it VERY HARD to believe someone installs a lift on a two storey building. Lazy buggers cant even walk up one floor ? :Sbtw...the spm std should b low...therefore i opt for atau considering the x-atau is too complicated..lolz Well, the lift could stall when both of them depress the buttons, but as soon as one of them lifts it, the lift would move again? It isn't stated anywhere that the button stays on until the lift reaches either floor. |

So what do u guys think of today physics ?
I think paper 1 & 3 is quite okay,paper 2 is just suck up on struktur,but essay should be ok. |

I think the physics papers is somewhat rather stupid! Especially about the gate logic thing! If X-ATAU, there is no such thing in real life!

common sense tells u tat the lift wont move when 2 buttons r pressed...
in real life tat's what we all did..but the truh is,only 1 button is pressed! impossible our hand so cun can press at same time physics overall ok but i lose a lot of marks already.stupid mistakes. This post has been edited by ^mtv^: Nov 29 2006, 04:37 PM |

haha.
Anyway, I'm quite confident is ATAU. Moving on, Physics 1 and 3 was okay..... I screwed up in paper 2.. forgot how to draw the rektifikasi penuh gelombang.... OMG>!!! |

QUOTE(tam_ironcup @ Nov 29 2006, 04:36 PM) i think can do both la, cos they gave two thing, the titisan air, and also they changed the kedalaman, i wasnt sure bout the frekuensi thing, so did bout kedalaman and panjang gelombang, the motor thing i said i tetap'ed the frekuensi dare not to say wrong or right... if i did liek that can ar?but from what the paper writen down there... gunakan tangki riak , penggetar yang boleh ubah frekuensinya.... i think both are accepted..... ubah or not oso can... but ur lakaran graph how er ? i draw secara linear leh.. |

QUOTE([ - i l l u s i o n s - ] @ Nov 29 2006, 04:40 PM) hmm.. In the front yes, but if they want a gambarajah for it, they will state it down at the question itself. Anyway, if you say 4 diod bentuk tetimbang untuk rektifikasi gelombang penuh, you will get 2 marks already. Don't worry!anyway the instruction say you can jawab berpandukan gambar rajah.. haha |

And then only u start ur exp. if i din use the fizik words like inersia....can ah???i put like masa untuk gasing berhenti.....I did inersia, quite easy . Just clip the gergaji and just ayun . LoL . my gerakbalas i put masa untuk bilah gergaji berhenti bergetar/amplitud gergaji.... is it right???? |
