RUBIDIUM IS MORE REACTIVE!!!! REACTIVITY INCREASES IN GROUP I DOWN THE GROUP!!!!!! anyway, rubidium and lithium arent in the reactivity series!!

thats resolved ..

i knowww...yar i was talking about water,...anyways everything is clear now.

i knowww...yar i wa talking about water,...anyways everything is clear now.

yup! sorry, read the initial discussion, and jumped in, only to realise that you guys were beyond the finish line!

 

[a.abid]

I got ur point but it still doesnt make sense... according to ur reasoning we would get less magnetic lines, it doesnt refer ro strength of the magnet...

oh right I got it....so wat will be the answer for that?

it doesnt matter if its water or anything else!!!

thats the thing that I always do..

Lol hell no sensitivity is rise of liquid per rise in temperature and responsivenss is how fast thermometer responds to change in temperature

so greater the bulb, the slower the response right???

yeah i know.

As far as i would have written
Weak field lines would not have influenced bigger magnet cause its mass would be greater and required force to turn would be more.
I know my answers sounds lame, I cant frame it properly

yes

oh ohkay.

the strength of the magnetic field is dependent upon the distance between field lines! the further away the field lines are, the weaker the magnet!

it doesnt give clear idea...ques was y bigger magnets cant be effected by weak magnetic field... pic just shows that weak magnetic field doesnt effect big compass

yes but what if it is a weak magnet... it doesnt effect big compass at all ?

lol no it shows tht we cant know if the magnetic field existed between tht area ( b/w the area free of field and the area having magnetic field) we can c the magnetic field lines for specified area even (thts wat i meant wid localized points)

I did say ur answer as satisfactory... and yes u are ryt about da pic but ques y was big compass is not effected by weak magnetic lines..
Come on its not something to make fuss of

 

[ashiqbal]

And here goes a proper framed response for the query of why a smaller compass is used:

1. Cheaper/portable
2. a greater force is needed to turn needle of larger compass, so it will only detect field lines close to magnet (further away from magnet, it will be deflected by earth's magnetic field, so inaccurate results)
3. there would be a greater distance between the points, causing an inaccurate field line to be plotted (eg, it will be less curved, etc)
4. there would be distance between the field lines, indicating a weakness of magnetic, whereas it is caused by monstrosity of compass (this by far, is the lamest point )

weak magnetic field lines means weak magnetic field there thus weaker force or propulsion weak enuff tht it cant push the compass needle thus compass would show no magnetic field there (it will point likely as south seeking pole and north seeking pole on earth)

wat was required was 2nd point only
bdw wats monstrosity..??
