    Guide and Tips-O Levels

    Oh, I already know IT means information technology. I just thought, considering the context, that it meant something else.

    Guide and Tips-O Levels

    In the physics 5054 syllabus, it says: "Certain learning outcomes of the syllabus have been marked with an asterisk (*) to indicate the possibility of the application of IT." What does IT stand for?

    I think it would be cotyledon too. The keyword in the question was 'geneotype different from the other three'. Both the fruit stalk and the pericarp come from only one of the parent plant, whilst the cotyledon is formed after the gametes of the two parents have fused.

    that's funny. SiO2 is acidic nature-- it should be doing the exact opposite of what the MS says.

    sin c = 1/n; where: c is the critical angle n is the refractive index. sin 37= 1/n n= 1.66 Refractive index can be defined as the speed of light in air divided by the speed of light in any other (denser) media. thus, 1.66= 3 x 10^8/ speed of light in plastic speed of light in plastic= 1.66...

    Resistivity of any given material depends upon three factors: 1. Length (direct proportion: more length = more resistance) 2. Material (Conductors such as copper have less resistivity) 3. Cross sectional area (inverse proportion: more cross sectional area = less resistance) Now, before I...

    Distance of loop A from the centre= 30cm Distance of loop B from the centre= 20cm i) Distance of 2N weight such that loop A becomes slack: 0.9 x 30 = 2 x d d= 13.5cm ii) Distance of 2N weight such that loop B becomes slack: 0.9 x 20= 2 x d d= 9cm My physics is absolutely horrendous so I...

    Are you talking about the storage granules in bacteria? As far as I know, those aren't a part of our syllabus.

    Alevel Questions

    I have been advised, by multiple teachers, to once go through a-level papers because a portion of the O levels exam relies heavily on them. I'm not so sure if this is true, but some of my teachers back at school made our class solve those papers, and I think they are really helpful. Plus, I find...
