how was physics p1?

qdtimes2 SG

i put D for qn 34

TIB657M SG

Q38 shoud be B because Since Ammeter deflects to the right, it is anti-clockwise. Thus, the pole which goes into Q is N (as stated on the question). The pole which is out of end P is S.

Placing N-pole in Q will make it a south pole.

Placing S-pole in P will make Q a south pole as well.

Qn 11 can't be C, what kind of potential energy does it convert to?

I think overall i got 4 wrongs

opps , sorry, i left that out. haha

it should be

kinetic- > heat.

lol that means i got 2 huh >_>

that sucks man . =.=

okay. Q4. pls lay out working plz. can't be B. Moi ans ish C.

Q10 moi ans is B (how can it be C???)

Q11 B (comfirmed)

Q15 (need help)

Q20. Should be C cannot be B! (moi reason. how can the reflected ray be bending out of the normal ???. B is possible cuz total internal reflection may be v. small [optical fibre], convinced by the beginning of the reflected ray.)

Q28, my fav. Answer should either be A or D. no other answers.

anyway, i think i will get oni 30/40

For Qn 20, look at the ray as it passes out of the glass block. It bends towards the normal, when it should be bending away.

Qn 15 is 8g - <1700J/(340J/g)>

Can't explain Qns 10 and 28 since i got them wrong

yiha093 SG

10 -

same height same pressure, enuff said ~.~

28 . read direction carefully and examine the function of a diode.

the phrase' passing a current through the battery in the opposite direction to that when it is discharging'

'it' refers to the battery . and the direction of the battery discharging is from + to - . hence my A.C needs to go in the direction to '+ ' of battery. hence i need find a diode which allows current to flow to '+' . which is A .

lol. read trhis

guy cried because of that air/vaccuum question . lmao
