well, i cook potatoes in microwave

 

[ibadsiddiqi]

I checked. Gamma rays and X rays are used for detecting flaws and cracks while infrared and microwaves are used for cooking and heating purposes.

 

[Silent Hunter]

so its correct ????????????????????

 

[ibadsiddiqi]

yup its correct. I can bet an A* on it!!

 

[jojo381]

guys wat was the answer to the mcq in which it was said the factor that donot effect the induced e.m.f of the conductor????? was it resistance or length of conductor.?????...i opt length of conductor.....!!

 

[ibadsiddiqi]

i selected resistance

 

[Usman17]

it was definitely resistance...!!

 

[ibadsiddiqi]

There was an MCQ which asked the best material to be used as tooth filings or something like that. WHat did you guys write? I selected the one in which the material does not expand when heated.Is it correct?

 

[ibadsiddiqi]

@Usman17 yea thats what i thought. You are sure this is the correct answer right?

expands as much as teeth, otherwise, you will get your filling out on a hot day

 

[ibadsiddiqi]

aww. I selected that option but then i erased it..

the material which expands the same as the tooth. if it doesn't expand and the tooth does, the tooth will peel away from the filling leaving a loose tooth filling inside ur teeth.

 

[Chicharito]

It was 'Expands the Same amount as the tooth'

 

[Usman17]

Yup!!!!

 

[Silent Hunter]

yep

 

[no.mercy]

For the microwave one it was definitely microwave to cook vegeis
and for the emf question it was resistance has no affect
and the filling tooth question came from the past papers..

And regarding Paper 4 Physics did you all mentioned the parallax error/no worn out scale/zero error coz it asked how can u take an accurate experiment..note the word accurate experiment

 

[Silent Hunter]

wich question in physcs 4?

 

[no.mercy]

the focal length experiment in ATP...

 

[ibadsiddiqi]

@no.mercy
yea i did. mentioned every single thing in detail

 

[no.mercy]

gud gud
