Semiconductor , you mean ?

B is the right answer . Where did you get this from ? I have past years before the year 2000 , but in B.M .

Yea the unit vector formula i do know that.But im stuck on that.How could i apply unit vector formula into it?

A big thanks to both of you. So does the phrase "........is a unit vector" means its equal to 1 in any circumstances?

Hey guys, I got more tips for SEJ SPM (paper 2 IIRC), For form 5 Tema 10 focus on Bab 2 subtopic, Gerakan Islah, Akhbar-akhbar and perjuangan persatuan-persatuan melayu. Tema 11 focus on Bab 5, sistem ahli, bab 6 , pembentukan Malaysia, Akta Malaysia and for bab 8 Memartabatkan BM and Dasar kebudayaan. For Tema 12(bab 9) look out for Dasar Luar Malaysia and Cabaran Masa depan especially K Ekonomi and K masyarakat.

Hope this helps
Okay whatever floats your boat...if you insist I am BU3 then BU3 I am to you then.

Guys, mind helping out on a few questions here?

1st pic: Question 9
2nd pic: Question 3 and 4

Although your answer B is correct, it is worthwhile to mention that, the weight of water displaced by a fully immersed polystyrene DOES NOT equal to the weight of the polystyrene, unless it floats freely on the water surface.

The weight of the polystyrene is negligible (0 N) because it has very low density.

Thus, we have

Tension = Weight of displaced water − 0.

Assuming that all Polystyrene (P) have the same cross section area, so volume of P3 > P2 > P1.

Since the parameters of water density and standard gravity, g are unchanged, then tension T3 > T2 > T1.

Depends on how heavy the object is I guess. Less dense or denser than water?
I will start this week.

I think is volume or TSA not size, correct me if I'm wrong.

Most books I've seen accept general. Specific would also contain the general word (eg "temperature of hydrochloric acid" contains the word "temperature") so I think it would also be accepted.

Certain Trial papers' mark schemes don't specify the particles interacting in a reaction

For BM komsas, I heard if the students' kbkk, persoalan, nilai and pengajaran answer are not same as the skema although they are rational will be wrong. My tuition teacher told me that dont be surprise if out of 40 candidate, only 5 will get correct.

So, how do you guys tackle Komsas part. Right now, I am doing trials paper to get familiarize with the accepted answers

Just a quick fact.

According to my chem teacher, rusting has been predicted for the past few years for Chem P3 but it never came out.

Try (b) . Answer , and why ?

Critical_Fallacy ?

On a separate topic, in the Penang Sejarah trials question 18 objective:

Raja Henry VIII telah memutuskan hubungan England dengan gereja roman katolik di Rom. Apakah kesannya?

A Pungukuhan kuasa politik
B menyokong usaha counter-reformation
C melangsungkan upacara perkahwinan
D menjadi pusat penyebaran agama

I could not find the answer to this, mainly due to not having the F4 textbook(3 reference books and nothing). I selected D because according to what I remember(and checked), Henry made himself the ketua kerohanian for the protestan church.
