hey, could you please help me with question 2 part d(ii) Nov 2007

 

[applepie1996]

sorry apple pie i meant 6

b)i)since alpha and beta are both of different charge they will deflect in opposite direction
beta has less deflection cuz of smaller charge
ii)alpha has smaller deflection as it is heavier than beta
iii)beta less deflection because higher speed and alpha speed slow so more deflection

c)i'll do it and tell

 

[Rakayz]

a)it is lagging pie/3 times so u start the drawing lyk dat and den intensity calculation??????
b)λ = ax / D this is the formula u shuld noe it by heart
540 × 10–9 = (0.700 × 10–3 x) / 2.75
=2.12 x 10^-3 m
=2.12 mm
c)i)the brighter fringes become brighter as more thickness to deflect through and darkness doesn't increase so no change
ii)increase in gap soo more place for light to place through so more fringes hence separation between them decreases

Thanks! but i dont know y i always face difficulty in waves :'(

 

[raamish]

help quickyly please: How to take out terminal p.d Is there a formula for it
If the current of a wire increases, why does it short b/c its resistance should decrease right because current is increasing. And does I and R have inverse relationship and can anybody give examples as when to use it
