Physics P1 and P2 Discussions

so for ur kind information, computers and robots malfunction sometimes

I dont....never have

 

[Hijab]

yes that is the correct answer...

 

[mohdumar]

so for ur kind information, computers and robots malfunction sometimes

overheating in socket were the words

 

[thementor]

overheating in socket were the words

proved correct again....

if a large current passes only plug and lead would be affected bcoz the appliances are getting the right supply. large current passes thru lead plug not thru appliances

 

[Kamihus]

Look like im gonna get 32 or 33 in MCQs in physics

 

[danial 234]

dont be sad. have hope in Allah

 

[Saad Mughal]

Look like im gonna get 32 or 33 in MCQs in physics

Still, better than me.

 

[Kamihus]

dont be sad. have hope in Allah

Still hoping for A* InshaAllah but I don't know how i got those MCQs wrong

 

[thementor]

M.C.Q's were more wierder than P2's questions.....im hoping for 36...and if it goes well then 37 in M.C.Q's

 

[thementor]

do
esnt matter as long as the answer is correct!

agreed

 

[Zuhsid]

exactly....becoz when one lamp has been broken resistance has reduced. allowing more current to flow..the current passes through the voltmeter instead of going directly through the lamp(filament broken)..using V=IR, resitance has reduced...so voltmeter reading decreases

i Also thought that the resistance will decrease.... but the voltmeter has a very humungous resistance (search it), that is why we no current flows through it when connected in series...... so due to the broken filament, it became in series, so overall resistance increased!!

Guys about that fuse one, remember there is a fuse present in the plug as well, which vil blow wen large current passess through it

Fuse is in appliances and plugs. The thing is that each plug of each appliance is getting the required current not larger but all together, the current passing through the socket is very high.

1) resultant one which shows the resultant line of two forces
2) wasnt it 25m distance
3) this ones correct
4) correct
5)i wrote the same too
6)correct
7)correct
8)correct
9)correct
10)correct
11) i guess mine is wrong cox i marked nucleus is dense with positive charge
12)yar there were option of pd qstn : A. it decreases B. it increases C. it remains 0v D.it remains 12v
13) wrong fuse doesnot blows its the socket one
14)correct
15) idk this i wrote GPE-KE-Heat
16) 'm not sure about mine
17)correct
18)correct
19)correct
20) it was the gain or loss of energy question
21)correct
22) the question of moment of sound and spring side by side one
23)correct
24) i wrote increase decrease
25)correct
26) oho it was the wave motion question of chosing which showed ripples
27)correct

2) I dun think so, sumwhere between 50 i guess
11) nope, in that case, alpha particles wud have been deflected
12) that LDR one? i wrote pd decreases
20) Particles cum close n they lose energy
22) Sound produces longitudinal, spring produces transverse waves
26) ripple tank ofcourse

Ques just said that they were plugged in n large current flows. It was not mentioned whether they were working alryt or not.

 

[Shadow]

Wat was the answer to that LDR mcq?

Well, that's what it means.

 

[Saad Mughal]

Wat was the answer to that LDR mcq?

Voltage decrease as when light shines on LDR its resistance decreases.

 

[Mohammad Farzanullah]

Wat was the answer to that LDR mcq?

i did A that the voltage decreased!
but i m not sure because at the last moment, i forgot the functioning of LDR
