how physics p42?

how was the paper

What was the ans to how to induce emf in the coil?

 

[demon29]

God knows

 

[urvi kapoor]

Lol.. And what was your distance..last ans

 

[demon29]

I left that 1

What was the ans to how to induce emf in the coil?

i dont know if m right bt i wrote:
1. move the coil across solenoid
2. move the solenoid across coil
3.use alternating current in the solenoid

the 1st and 2nd answers look about the same to me but maybe i`m wrong.
i wrote rotate the solenoid instead

what was P output for the last Q?

 

[rabos1]

No I'm more worried. Seeing the votes make me cry. You guys found it average?? I found it soooooo hard.. so worried.. :'( didn't do a lot of parts..

 

[Dolly96]

Lol.. And what was your distance..last ans

I got 70 km

ya they are similar but it was just about changing the magnetic flux so may be they will award mark for it

I wrote increase the current
get a small coil
increase the turns

 

[nabeelah]

for section B how did you guys draw the circuit?/

 

[Ujjwal Basnet]

I wrote increase the current
get a small coil
increase the turns

well i am afraid u did it wrong all of these would increase the emf induced maybe..but it wont induce emf

 

[Ujjwal Basnet]

for section B how did you guys draw the circuit?/

i just drew thermistor and a resitor in series connected randomly to a op amp

 

[Sheeya]

yeah yo

well i am afraid u did it wrong all of these would increase the emf induced maybe..but it wont induce emf

ur right. it can't induce emf, but only increase it

 

[nabeelah]

i just drew thermistor and a resitor in series connected randomly to a op amp

yeah i've also draw something like this
but some are saying that the drawing should not include an op-amp!

 

[Dark Blade]

There was no op-amp, it was a simple potential divider circuit. We were only provided with a thermistor, resistor of 2.5 kilo ohms and a 4V power supply.

but some are saying that the drawing should not include an op-amp!

well may be they are right but i dont know how to vary the voltage without the use of an omp amp so i drew it
