any ramalan for agama???? aihhhh

5. the current menteri pelajaran is muhyiddin. but then in the news said najib. wtf?

Need help pyhsics !! must A help!! paper2

can some1 help me with these 2 questions ?





answers are 10. 6cm and 37. C but why ?

my friend is the son of muhyiddin , he said no , no such thing

guys,how to do this?

for question 10

10N = 4cm
1N = 0.4cm
30N = 12cm

in parallel series = 12/2
= 6cm


for question 37

gradient = (1.2 - 0.4)/(0.84 - 2)
= 1.25 C

10.

4cm 10N

got 30 N = 4x3

12cm

it asked EACH spring not 2

because got 2 spring then divide 2

12 divide 2 =6 )

1more question lazy see now 7.19 dinner time

given R=[perfect squares that are less than 8]. Find the possible number subsets of R.

A 1
B 2
C 3
D 4
D

Any rational number that is the square of another rational number. In other words, the square root of a perfect square is a whole number. For example, 0, 1, 4, 9, 16, 25, etc. are all perfect squares.

the first one is

10N will give 4cm
30N will give 12cm

if they are arranged in parallel( like in the diagram)
the lenght will be divided

if they are arranged in series, the length will be the same.
if two of the springs are arranged in series,then it will be 2x where x is the extension

the second one is

according to the formula V=IR, R=V/I( gradient of the graph)

Added on November 27, 2010, 7:29 pmyou are correct, but i don't understand why it is D.

you said perfect sqare is any number that when square root the answer is an integer.

so 0,1 and 4 are perfect sqaure,so isn't the answer suppose to be C (3)?

the ans shld b either 1 or 4.

so there are 2 answers?

the question is a little bit cacat,they should put find the possible ELEMENT of R. subset is like..set...isn't it?

woah...so hardcore also...shud complete physics by tomoro cause on Wednesday afternoon (after add maths), we'll be tired and we cant study..i think

Yeah la . and yet havent i memorize all the nilai moral
shyt yeah .

Some consider 0 as a perfect square but some not, because some ppl definite perfect square as square of a POSITIVE INTEGER. If not wrong, the syllabus in our text book doesn't include 0 as a perfect square. The answer should be B.

hey guys tell me vhat to study, i just finish 2005 to 2009 paper 2 mathematics , all of it , should i do paper 1 math , study agama or physics?? i dont know which to pick now

and u mean 4 is not a perfect square?

according to the question, it only needs perfect square that is below 8. Thus the perfect square that meet this requirement is 1 (1^2) and 4 (2^2)....the next perfect square is 9 (3^2) and cannot be included

we have the whole afternoon on Monday to memorise the nilai

physics....it's a lot
