Discussion for physics P12

[umair1161]

Hey guys! How was all your papers?? i have some doubts of my own....if anyone can answer them then that would be great.....so here goes:

The capacitor question (discharge and recharge)....what was the answer??

The circuit in which we should place the ammeters and voltmeters.....what was the answer for that??

the last question regarding the neuclion number......

the density of the liquid??

the frequency order for those waves......

and the waves required for the television to recieve from satelite.....

Thanks and even u can post your doubts here!

Hey man I did paper 12 too!
here is what i wrote.
I wrote C (discharge and charge) for that question
For the circuit question it was A. they were all ammeters because they were all connected in series
I wrote the nucleon number as P because it said it was a nuclide
The density of the liquid was A, 0.875 because 8 cm^3 water evaporated and there was a difference of 7 grams on the scale so density=Mass/Volume
I wrote Infrared>Visible light> UV for the frequency
The answer for that one is radio waves for the satellite.
Hope I helped. I'm positive all these answers are correct. Hope we both do well

 

[AbhishekTSS]

I wrote discharge because when the switch was changed the circuit for the battery was not complete so the capacitor cannot charge.

Hey abishake im from ois to

 

[AbhishekTSS]

Oh really? what's your name? what grade? How did you do?

 

[Matthew725]

What did you guys put for the answer regarding the women's heels and pressure. I'm aware it should be the smallest one. So was the answer A?

 

[AbhishekTSS]

Yes. It was A because the area is smallest so the pressure is greatest.

 

[vishalgodhani]

i

Yes. It was A because the area is smallest so the pressure is greatest.

wrote B

 

[humdono]

The answer for that one is radio waves for the satellite.

microwaves are used for satellites not radiowaves

What was the answer for the three bulbs and one getting removed I said it gets dimmer and wb the circuit breaker

 

[Igcse giver]

guys what about work and power graph?

 

[lol_foreva]

What was the answer for the three bulbs and one getting removed I said it gets dimmer and wb the circuit breaker

it does get dimmer, as for the circuit breaker itz in the live wire and it breaks the circuit

 

[lol_foreva]

guys what about work and power graph?

power increases as work done increases

 

[lol_foreva]

guys wat bout, the accleration question(greatest speed and shortest time) and wat bout the weighing scale ? is it 500 N?????

 

[hamza budhani]

for weiging scale its waz 500n and for acceleration it htink its C

 

[lol_foreva]

p

for weiging scale its waz 500n and for acceleration it htink its C

phew! for the weighing scale!
are u sure bout th acceration

 

[hamza budhani]

which question waz acceleration im not sure

 

[lol_foreva]

which question waz acceleration im not sure

um.... wer they are dropiin a ball through sections of air,and timin it.......
J,K,L and M

 

[hamza budhani]

people r sayn it D

 

[lol_foreva]

N

people r sayn it D

NOO!!!!!!!!!!!!!!!!!!!!!!!!

i put A
