Wouldn't die lah. 1 mark only. so kiasu meh ?

i wan is fact..i also kia su..it just said mercury la...so confuse me..i changed it from 90 cm Hg to 20cm Hg...i wan learn thing la.

spm passed ady

In that case, your teacher has the ultimate power to give exam marks. Your answer is correct.

hey
for moral esei
my school teacher advise us to use this format:
N ( 3 in 1 sentence)
P ( 2 in 1 sentence)
C
C
P ( 2 in 1 sentence)
C
C
P ( 2 in 1 sentence)
C
C

this format is done in one paragraph
IS this format acceptable?

if my teacher give me wrong?

90cm Hg.

at point X,i think is 90cm Hg.coz normally when we calculate pressure at a point,we always add atmospheric pressure.when in vacumm,the pressure is 0 so it is 70cm+20cm...tat is what i think la....correct me if i am wrong

As I say, just donate that 1 mark lah ... Tuhan tau you r right

abiotic factors of sustainability in microorganisms >> classification and features of kingdoms

My mind has a low reading and writing speed; I didn't touched kingdoms at all back then.

dun want.. 1 mark also important la...hope the skema is my ans correct..cause it just said mercury..not said total pressure

question no 1 and 2 pls !

1. 10/4=2.5m/s
2. 340x5=1700m

All in one paragraph? I don't think so. And for the nilai, I would advise you not to cramp 3 in one sentence. Its best to write one nilai in each paragraph, following by its respective huraian and contoh.

i duno this ques. help me.

When a footballer kicks a ball which is at rest, a force of 20N is applied in 0.5 s. The impulse that is given to the ball is ?

use the impulsive force formula.....

All in 1 paragraph..Cannot separate..But nilai must be separate..

N
P (2 kata kunci)
C
C
N
P (2 kata kunci)
C
C

At x or at any place same level of x, the pressure is the same.
Say at the left side of x, we can do a equation which looks like this
Total Pressure(at left of x)=P(atm)+P(20cmHG)
Unfortunately, we dont know the atmosphere pressure. Therefore, we can do equation for x
Total pressure(at x)= (70cmHG)+P(20cmHG)
since at same level, pressure is the same, pressure=90cmHG

i know i have to use the impulsive force fromula. but what is the value of m?
