wat abt da direction of force on da beta particles. dere ws a question sumthin lyk dat, ryt?

i put into the page but all my friends said its out of the page

route of the beta particles? i put upwards

 

[natsume hyuga]

out of the page

I think u r right main to paper dekh kaay heyy sab kuch bhool giyaa thaa

dats wat i'm talkin abt. i put out of da page

Beta is into the page (which means towards the north, hence upwards and the current flows to the left not the right as you will use the right hand rule because you don't know the current if they were asking for the force then you will use the left hand rule.)

Guyz how much do u think a ranking can score for example the top on a certain city?

 

[ismaillfc]

what is the process which the waves go to point P?

 

[Ahmedboombox]

Diffraction

 

[ismaillfc]

Diffraction

but diffraction makes the waves curved so they can't reach point P? don't we have to replect the wave so it will be able to reach P?

 

[ismaillfc]

Diffraction

reflect**

 

[Ahmedboombox]

No , the waves are passing through a gap ( the straight waves hit on obstacles) making them bend and therefore diffract check your book the chapter about waves.

diffraction.

 

[natsume hyuga]

also what was the question abt the change of state ?

 

[bluefa1con]

dat ws 2.4V, i guess

no it was 6 V

 

[Muhammad Nihal]

evaporation

beta particles were outwards

 

[bluefa1con]

yes the wave were defracting
