This is what my graph looks like... Different from yours :'( Dang.

Ferrari_RoXz SG

Ya, i confirmed with the textbook. Normal Television is radio waves. But satellite television is mircowaves. Heng sia, last min change answer! Too bad my 1st question units wrong.

My focal length I saw 1.9 cm leh. But I scared go put 2cm. Hope its correct.

Occam's Razor SG

ok, I cfm-ed its microwaves not radio waves :(

Twenty8 SG

me2 cfm is microwaves.but i wrong ><

seow SG

lol i put 110N

慈しみ SG

Ouch, one mark. Wrong le. >< didin't take note of the satellite thing.

eagle SG

actually satellite tv can function both with radio waves and microwaves

it is just that the method used for broadcasting is different from normal TVs

so how.? cannot be that they accept both answer.

only possibility is when they set wrongly.

eagle SG

why cannot accept both answers

there are still wrong answers mah... i.e. if someone go and put infra red or UV, confirm wrong

Theguiltshow SG

So they may accept both radiowaves and microwaves? I wrote the former... :(

And for the circuit question I made a really careless mistake and wrote P = IV then I = V/P so I got 0.5A instead of 2A. Will I still get marks for that? Because of this, I also got my combined resistance question wrong. But method correct for that.

That's... what, 5 or 6 marks gone?

But I think the paper was okay.

I'm so upset over my careless mistake sigh :'(

Vendettus SG

6.Heating curve (draw), then recall Q

Dang, I didn't draw a curve... Haha, I drew straight lines instead. Two marks... gone.

Wrote radiowaves instead of microwaves, another two marks gone.

That's what happens when the paper is easy. No longer is it 'survival of the fittest'.

ECF perhaps?

Theguiltshow SG

It's the survival of the most careful haha. Sadly I am not one of those. Oh well.

The radio waves question is 2 marks?? O_O For the heating curve is it decreasing gradient first then straight line (change of state = same temperature) then increasing gradient? (all curves except straight line)

MyPillowTalks SG

i wrote 110g instead of 0.11kg die lar

Maith SG

HAHAHAHA so easy! :DDD

the only qn i dunno is the vector one \:

i put 5N,dunno correct or not

Maith SG

i wrote 110g instead of 0.11kg die lar

same lol,but my teacher say maybe can :D

Vendettus SG

HAHAHAHA so easy! :DDD

the only qn i dunno is the vector one \:

i put 5N,dunno correct or not

5N is correct.

13Warriors(2) SG

My focal length put 2 cm sia... hope can get correct.

eagle SG

i wrote 110g instead of 0.11kg die lar

as long as they did not state that it must be in SI units, it is correct

MyNameisNas SG

physics o lvl

this is how my graph looks like...

Maith SG

5N is correct.

serious? hahaha i use pythagoras find sia! :D
