1st of all, state which type of engineering...a simple layouts of engineering

Electrical Engineering
Electronic Engineering
Aerospace Engineering
Aeronautical Engineering
Marine Engineering
Acoustic Engineering....well u get my point, state which 1

PS....i recomend u search for info from other topics, otherwise open a new thread. This is, what's written on the title...SPM, nt after SPM

There are electrical and electronic engineering, mechanical engineering, chemistry engineering, civil engineering, electrical and computer engineering, mechatronic engineering, environmental engineering, electronic and communication engineering and so on.

For the information of SPM 09 students XD
You may need it too, for your future

mechatronic engineering? dont study in malaysia. no job in malaysia. thats what i heard form senior

kinda confused with this question. please help me.

2(6x(squared) + 29x - 5 )

should the answer be 2 ( 6x + 5 ) ( x - 1 )???

or i mistaken?

but i try redo get some else...but its not possible to get -5 if i use different value...i might miss something. please pointed it to me.

NEVERMIND...GOT IT ALREADY...

So rajin.

lol..what's the ques? chapter what?

Attached thumbnail(s)

what is resonance and natural frequency?

as i know, these is not in form 5, i think is stpm standard
btw, the question is not complete i think
anyway, frequency=1/time, time is the time taken for the spring to make a complete oscillation?

Added on February 11, 2009, 2:36 pmresonance is the natural frequency by a forced occilation

Ya Malaysia haven't been developed in this aspect yet. But maybe a few years later it will be quite a good path because it's quite new. Just like IT graduates 20 years before.

Btw i advise not to take E&E engineering la, because too many people taking it and Electronic Engineers salary is very very low now. Not worth for it. I heard my cousin's company employing Electronic Engineer for only 1.2k. Study chemical engineering instead.

James carries out an experiemnt using a simple pendulum and discovers that its frequency is very high. He changes the weight of the oendulum from 20g to 24g. what is the effect of thei action?

A. no change
B. The natural frequency of the pendulum increases
C. The natural frequency of the pendulum decreases
D. the pendulum's frequency decreases

Is the answer A?

yaya.. why..? mind to explain pls

Because period of oscillation is proportional to length of the pendulum. Mass does not affect the frequency. I had this question in my physics test. I'm still in form 4 chapter 1 so I might be wrong

okay..got it..thanks

Added on February 12, 2009, 4:34 pmA few questions on WAVE

Q1 what is the factor which increases the natural frequency of an oscillating system?
A Gravitational acceleration is reduced.
B. The spring hardness is reduced
C. The load mass is reduced
D. The load mass is increased.

Q2 A simple pendulum oscillates with period T. If its wavelength is increased to 9 times the original lenght, find the new period.
A. T/3
B. T
C. 2T
D3T
E 4T

explain please.

Q1. B i think because when spring is softer, it bounces faster
Q2. C i think. but i calculated 9T
not sure

wow, another future straight A student (DarreN)here....wen i form 4, i like wth the teacher is talking abt....LOL...even now, i stil duno abt form4 physics...they make me

This post has been edited by styrwr91: Feb 12 2009, 06:12 PM

sure or not? too many ppl taking it, see the financial prob adi no more ppl want to take liao....still got ppl go in meh?

Q1 C
pendulum : the shorter the pendulum/the larger the gravitational strength, the larger is the frequency
spring : the smaller the load mass/the harder the spring, the larger is the frequency

Q2 B
refer to explanation above

what is isomerism and isomers? does methane contains isomer?

Isomers are compounds with same molecular formula but different structural formula, Methane isnt isomer bcause it has one Carbon only. H-H-C-H-H
