Yes im not sure about that too. Asked my teacher this before so im quite sure the ans is d. Forgotten her explanation already though.

when only s2 closed, brightness decreases because less current passes bulb.

answer is wrong

The answer D is not only wrong for S2 is closed, but also incorrect when S1 is closed.
yup ... overlooked something. Answer C is correct.

A multiple choice question usually does not require extensive mathematical calculations or proofs. If manutd96 can imagine the series and parallel circuits and understand the principle of voltage division in series circuits and the principle of current division in parallel circuits, he does not need much calculating effort to infer that the brightness of the bulb is unchanged when only Switch S1 is closed, and the brightness of the bulb decreases when only Switch S2 is closed.

In fact for secondary level students, simple explanation is much more effective to understand than the detailed calculation.

A & B are wrong because parallel connection (same voltage)

About the trolley, since force is constant, acceleration is constant too.

v=u+at , where u = 0

v= at

and

E=0.5mv^2 = 0.5m(at)^2 = 0.5ma^2 t^2

so

the relationship E and t is same to quadratic function which is a U shape graph .

Answer = A

What do your teachers talking about writing chemical equations with physical states ? If you don't write physical states, you get mark deducted ?

No you won't.  For SPM you don't have to write the state of matters but for STPM, yes.

yeah ... as what i heard as well, just to reconfirm, thanks

SPM 2012 : why does the voltmeters show different readings?  Isnt both measuring pd across 2 same points?  Why is it that v2 is calculated by 6-1.5??
*
that question has problem. from the diagram, two voltmeters are connected in series. every year spm paper has wrong questions. shame on the persons who set the questions. doh.gif

If there is a problem question in SPM paper, yet there is no announcement for the correction, what will you do ?

Example, plot a graph A against B. But you know the right graph should be B against A. Which graph will you plot ?

1. A against B (which is wrong)

2. B against A (which is right but wrong based on the question)

Technically speaking, in mathematics, it doesn't really matter whether plotting a graph A against B or vice versa. For example, in the Velocity-Time graph, we normally plot the velocity (v) against time (t). Even if it is plotted inversely, we still can extract some useful information from the graph. Therefore, sometimes plotting a graph A against B out of the norm is NOT technically considered “wrong” as one would imagine. icon_rolleyes.gif

You are right.

But you will get the wrong gradient as students are taught to find gradient by using formula y/x

So does it mean here that the cathode ray tube acts like a diode?

Cathode ray tube only function with d.c. No current passes through CRO. Answer is C
